Kentucky’s Nursery and Greenhouse Industries:

Employment and Product Forms

is the second in a series of articles reporting results from the Green Industry Research Consortium’s survey of the U.S. nursery and greenhouse industries. The most recent survey was conducted in 2014 in all 50 states, reflecting 2013 data. Drs. Alan Hodges, Charles Hall and Marco Palma took the lead on this survey and published the results in the Southern Cooperative Series Bulletin #420, Trade Flows and


Marketing Practices with the U.S. Nursery Industry, 2013 (available at http://www. The Kentucky data have been extracted from SCS Bulletin #420, and additional computations have been made from the original data. This article summarizes employment data and the type of products sold.

Employees The average number of employees

of responding Kentucky firms was 4.5 permanent/fulltime employees and 4.1 temporary/part-time/seasonal employees. Although the percentage of responding firms in various annual sales categories was similar to the national average, Kentucky’s average employment per firm was lower than the regional and national average (Table 1). Approximately 54% of the 1,100 employees engaged in Kentucky nursery

ents reported reducing their permanent employees by 9% and decreased temporary employees by 17% over the five years from 2004 to 2008. By comparison, respondents had increased their permanent employees by 11% and temporary employees by 14% over the previous fiveyear period, 1999–2003. Nationally, there was little change in number of employees per firm between 2003, 2008 and 2013 surveys. Data from

an economic-impact assessment of the green industry as a whole revealed total, direct employment was 1.86 million jobs for the U.S. and 22,147 jobs for Kentucky.

Plant types sold Approximately 16% of total sales by Kentucky grower respondents were from deciduous shade or flowering trees in 2013, compared to 12% in 2008 and 42% in 2003 (Figure 1). The vast majority of

and greenhouse crop production in 2013 were permanent employees, compared to approximately one-third in 2008. H2A employees were not significant for survey respondents in 2013. The absence of a few of the larger firms from the survey data could have skewed these numbers. Kentucky respondents to the 2003 survey averaged 7.2 permanent employees and 6.2 temporary employees at that time. On the average, Kentucky respond-

deciduous shade trees are produced by six field nurseries in Kentucky. It could be possible that a significant portion of the deciduous tree production was missed in 2008 and 2013 due to sampling error or lack of response. The percent of total sales for deciduous shrubs, evergreen trees, broadleaf evergreens and bedding plants increased in this recent five-year period. The percentage of total sales reported for roses, herbaceous perennials and vines/ground covers decreased since the last survey; however, the random sample for the survey in 2013 may have missed the larger producers of herbaceous perennials, as the authors’ observations in the field did not note decreased production. Bedding plants, flowering annuals and vegetable, fruit and herb transplants, represented 8.6% of sales in 2003, 17.5% in 2008 and 22% in 2013.

Given the fact that overall sales increased between each of the five-year survey periods, the increased percentage of sales from bedding plants is even more impressive. This growth is likely from the expansion of larger greenhouse operations as well as an increased number of smaller growers adding “color” to their product mix. Roses were 1.2% of sales in 2003, 12.7% in 2008, but only 6% in 2013. New continuous-bloom, low-maintenance landscape roses such as the Knock Out® rose and the presence of the rose rosette disease contributed to the up-and-down nature of the production of this crop in the past 15 years. Herbaceous perennials increased from 6.6% of sales in 2003 to 12.2% in 2008 and were back down to 6% in 2013. Kentucky industry respondents reported that 33% of plant sales were from native plants of all types in 2013,

which was much more than reported for 2008 (3.9%) and 2003 (11.6%). This is somewhat in line with the Appalachian region (26%) and higher than the national average (17%). On average, respondents in the Appalachian region and nationally also reported an increase from 2008 to 2013 in the percentage of native plants sold. Some of this is possibly due to acknowledgement of the number of traditionally grown plants that are actually native as well as an increased demand for native plants to meet the demand for restoration and conservation projects and, possibly, garden-center customer demand. It is important to note that total sales increased during this period, so a decrease in the percentage of sales from a given plant type may not reflect a decrease in production of that plant type but perhaps increased sales of other plant types.

Average percentage of total annual sales by product form for Kentucky respondents in 2003, 2008 and 2013.

Product forms Containerized plants comprised 79% of total sales in 2013, compared to 57% in 2008 and 39% in 2003 (Figure 2). This percentage is similar to the region average. Tennessee nurseries marketed a much higher percentage as bare-root plants than Kentucky or other states in the region. This is consistent with the reported increases in that 10-year period for bedding plants, roses, herbaceous perennials and others that are primarily grown in containers. This also includes an observed increase in pot-in-pot (inground containers) production of trees and shrubs in the industry during that period. Balled-and-burlapped plants averaged 15% of survey respondents’ sales in 2013, down from 49% in 2003. These findings are consistent from our observations in terms of the range of individual producers; however, they differ somewhat from our assessment of a relatively small number of large nursery operations that account for a significant portion of the production and may not have responded to the survey. For these nurseries, a significant portion of their sales comes from field-produced trees. Personal observations also showed a decrease in field-grown tree sales and reduced re-planting following the recession of 2008–2009. The share of total plant sales as bare-root plants was 25% in 2008, 1% in 2013 and less than 1% in 2003. Advancement of several hybridizers of herbaceous perennials (daylily and hosta, in particular) in Kentucky could account for the increase in bare-root plants sold as well as the increased mail-order sales and sales of herbaceous plants from 2003 to 2008. Increased container sales between 2008 and 2013, coupled with personal observations of Kentucky operations of a trend toward more production and marketing a higher percentage of herbaceous perennials in containers, could explain the decrease in bare-root plant sales from 2008 to 2013. 2 Nur sery Views • S pr ing 2016

Economic Impacts

of the Kentucky Green Industry By Dewayne L. Ingram, Ph.D., Horticulture, University of Kentucky; and Alan Hodges, Ph.D., Food and Resource Economics, University of Florida

Nurs ery Views • Spri ng 2016


green industry — comprised of firms engaged in the production and use of landscape, floral crops, related supplies and equipment and the design, construction and maintenance of landscapes — has a significant impact on Kentucky’s economy. Green-industry enterprise owners, managers and employees should be aware of their economic impacts, and policy makers and other state leaders need to know the importance of this industry when potential laws, regulations and resource allocations are considered. The Green Industry Research Consortium is a group of horticulturists and economists conducting a multistate research project through the Agriculture Experiment Stations at land-grant universities throughout the U.S. Drs. Alan Hodges, Charlie Hall, Marco Palma and Hayk Khachatryan, project team members, published a paper in 2015 entitled, “Economic Contributions of the Green Industry in the United States, 2013.” The data for this report were compiled principally from the Impact Analysis for Planning (IMPLAN) and several other current, national economic databases and


reports. The study results for Kentucky are summarized here. At the national level, the U.S. green industry in 2013 was estimated to generate $136.44 billion in output (revenue) and to employ 1.60 million people in full-time and part-time jobs. The total economic contribution of the industry, including regional multiplier effects in other sectors of the economy, was $196.07 billion in output impact, 2.04 million jobs, $82.47 billion in labor earnings and $120.71 billion in value-added contribution to gross domestic product (GDP). Since 2007–08, green-industry contributions in 2013 increased by 4.4% for employment and 2.7% for GDP in inflation-adjusted terms. Growth in the industry was highest for wholesale and retail trade, while production and manufacturing declined. Some terms used in the report — particularly output, output impact and value added — require some explanation. Total output or revenue is basically total sales throughout the revenue stream; except for retailers, it represents the gross margin (sales less cost of goods sold) to avoid double counting with wholesale

sales to retailers. Value-added impact by the industry is a measure of the net contribution to the U.S. gross domestic product, calculated as total sales (output) minus the intermediate sales in the supply chain (cost of inputs to the sector). The industry groups related to the green industry that were evaluated in this study included production and manufacturing, horticultural services and the wholesale and retail trades. The production and manufacturing group included nursery and greenhouse production and lawn and garden equipment manufacturing. The horticultural-services group encompassed the landscape-services and landscape architectural-services sectors. The wholesale and retail-trade groups accounted for green industry-related sales and economic impacts from 12 sectors, including: • wholesale establishments that distribute horticultural products (durable and nondurable) to retailers and end users • lawn and garden supply stores, building material and supply stores and homeimprovement centers (e.g., Lowe’s and Home Depot) • florists

impact of $559.3 million to Kentucky’s economy in 2013. The nursery and greenhouse crop-production sector was comprised of 67 employer firms, with revenues (sales) of $92.3 million, directly supported 1,100 jobs and had an overall employment impact of 1,136 jobs and a

value-added impact of $6.3 million to the state’s economy in 2013. The landscapeservice sector, excluding landscape architectural services, was comprised of 1,111 firms, had revenues of $545.5 million, supported 9,191 jobs directly, had an overall employment impact of 11,026 jobs

• general merchandise stores with garden departments (e.g., Walmart and Target) • non-store retailers such as mail-order or internet retail sales • other retail establishments that offer horticultural goods as a minor sideline, such as food and beverage stores The activity of independent garden centers and garden chain stores are captured in the data for lawn and garden supply stores. Kentucky’s green industry in 2013 directly supported 18,821 jobs and generated $1.12 billion in value-added impacts and $1.98 billion output impacts to the state’s economy, based on direct output (sales) of $1.52 billion. The total output impact was $96.6 million for nursery and greenhouse crop production, $797.6 million for landscape and horticultural services (including landscape architecture), $255.0 million for lawn and garden equipment manufacturing, $211.0 million for the wholesale trade sector and $622.9 million for retail trade sector. Valueadded impacts to the economy by industry segment were $66.3 million for crop production, $493.0 million for horticultural services, $57.7 million for equipment manufacturing, $135.1 million for wholesale trade and $368.3 million for retail trade. The sales, output impacts and value-added impact are presented for all Kentucky industry sectors in Figure 1. Of the total employment impact of 25,753 full-time and part-time jobs in the Kentucky green industry in 2013, the largest impacts were for horticultural services (11,208), wholesale trade (1,076) and retail trade (8,212), followed by crop production (1,136) and manufacturing (793). Direct jobs in the green industry and total employment impacts, including indirect and induced jobs generated in other economic sectors through the multiplier effect, are presented by the various industry groups in Figure 2. The two industry sectors most recognized as part of the green industry — nursery and greenhouse crop production, and landscape services — together had 10,290 direct jobs and an overall employment impact of 12,162 jobs, with $656.8 million in total sales and value-added

and generated a value-added impact of $482.8 million for the economy. Lawn and garden equipment manufacturers in Kentucky generated $197.0 million in total sales, the 13th-highest state in the U.S., with 417 employees and an output impact of $255.0 million. Although sales from Kentucky’s nursery and greenhouse crop production were less than for the lawn and garden equipment manufacturers ($92 million vs. $197 million), crop production accounted for more than twice the number of jobs (1,100 vs. 417), while landscape services accounted for 22 times the number of jobs (9,360 vs. 417) and more than ten times the earnings impact ($356 million vs. $30 million) of equipment manufacturing, due to the labor-intensive nature of crop production and landscape services. The wholesale and retail trade industry group is comprised of eight individual sectors as described above. Of the total Kentucky green industry, the wholesale and retail trade industry group represented 41% of direct jobs, 45% of the value-added impact and 42% of the output impact. Wholesale establishments are those that distribute horticultural products to retailers, including plants, chemicals, fertilizers and other supplies and various types of lawn and garden equipment. The wholesale trade represented 4% of Kentucky green industry jobs, 12% of value-added impact and 11% of output impact. Similarly, for the U.S. as a whole, wholesale trade represented 4% of greenindustry jobs, 12% of value-added impact and 12% of the output impact. In Kentucky, output of durable and nondurable horticultural goods by the wholesale and retail trade industry group totaled $669.2 million in 2013, which supported 7,944 jobs directly in the industry and a total employment impact of 9,288 jobs, generated value-added impacts of $502.5 million to the economy and resulted in an overall output impact of $834.3 million. The retail-sector firms are those that sell directly to consumers. The retailer sectors accounted for $496.0 million in output and supported directly 7,182 jobs. In fact, retail trade represented 38% of all Kentucky’s green-industry jobs and


31% of the output impact to the economy in 2013, compared to 26% and 18%, respectively, for the U.S. In the Appalachian region, the retail trade represented 27% of the green-industry jobs and 18% of the output impact. The importance of the retail sector to jobs and output impact in 2013 was greater than in 2008 for both the U.S. and Kentucky industries. The retail trade group had 3 times the output impact in 2013 as the wholesale trade in Kentucky, while the retail trade had only 1.5 times more output impact than the wholesale trade in the U.S. It appears that in Kentucky, as well as the region and nationally, growth in the retail sector outpaced growth in the cropproduction sector. The total value-added contribution of the U.S. green industry to GDP was $120.71 billion, including labor-income impacts of $82.47 billion, other propertyincome impacts of $28.91 billion (in the form of interest payments, rents, royalties and corporate profits) and impacts on business taxes paid to local, state and federal governments of $9.30 billion. The total value-added contribution of

the Kentucky green industry to the commonwealth’s economy was $1.12 billion, including labor-income impacts of $740.3 million, other property-income impacts of $284.8 million and business-tax impacts of $94.4 million (Figure 3). Landscape services and lawn and garden equipment stores had the greatest contributions on Kentucky labor income and property income impact. Florists had the thirdhighest impact on labor income but had little impact on property income. The Kentucky green-industry retail sectors — lawn and garden supply stores, including home-improvement and independent garden centers — represented 73% of the output impact (Figure 4) and 55% of the jobs in these sectors. This type of firm represented 59% of the U.S. green-industry retail-sector output impact. Unfortunately, the available data would not allow the separation of independent garden centers within this sector. General merchandise stores, including bigbox stores such as Walmart and Target, represented 8% of the Kentucky greenindustry retail-sector output impact, while florists represented 15%. Non-store

retailers, such as mail-order and online vendors, represented 3% of the output impact of Kentucky’s green-industry retail sector in 2013 but only 1% in 2007. This would imply that sales of plants and garden supplies by mail order or internet sales have become more important to Kentucky in recent years. Nonstore retailers represented 9% of the U.S. green-industry retail-sector output impact in 2013 and 3% of retail sectors in the Appalachian region. The U.S. average output impact per crop-production firm was $2.07 million, while the Kentucky average was $1.8 million. The U.S. and Kentucky average output impact per firm for the other sectors are similar, indicating that Kentucky’s nursery and greenhouse firms are smaller than the national average but that landscape services firms and retailers are of similar size, which is generally expected because most of these firms serve a local area. Overall, the value-added impact of the green industry in Kentucky of $1.12 billion represented 0.60% of GDP in the state in 2013, as compared to 0.72% for the U.S., ranking Kentucky 41st among states. By way of comparison, the value added to the state’s economy by the green industry in Kentucky was greater than in West Virginia but less than in Tennessee, North Carolina, Ohio and Virginia. Previous studies in 2002 and 2007 reported total value-added impacts of the green industry in Kentucky at $651.1 million and $1.07 billion, respectively. The change, adjusted for inflation, for the period 2002 to 2013 was 44% or a 4% annual average. It should be noted that this period includes the great recession of 2008–2010. The Kentucky green industry is obviously an important element of Kentucky’s economy and is present throughout the state. The diverse nature of the industry limits its visibility compared to some industries; therefore, it is important to recognize and communicate these contributions. Data presented here can be used to engage governmental, business and agricultural industry leaders in conversations about the needs and opportunities for the industry. 2

Plant Profile


Katsura Tree Is Truly a Delight for Fall Color By Eric Garris, Bernheim Arboretum and Research Forest

Nurs ery Views • Spri ng 2016


our search for trees that bring fall color into the landscape, we often choose favorites such as maples and oaks. Often overlooked is a diminutive tree that provides good shade as well as spectacular autumnal foliage. The Katsura tree (Cerciophyllum japonicum) is a native of Japan and China, but it grows well throughout the central and midwestern U.S. in hardiness zones 4–8. The Katsura’s heart-shaped leaves emerge in the spring with a rosy tint. Flowers are produced on both male and female plants but are rather insignificant, resulting in small, 3/4" seedpods on female trees. In summer, the mature leaves give this tree a bluish hue, which contrasts nicely against surrounding landscapes. Reaching 30' to 40' in height with equal spread at maturity, it is an inter-

mediate-sized tree that should be planted in full sun to partial shade, and it is well suited in the landscape where space may be limited. Pruning is not necessary other than for form, if needed, when young. It does well in the urban environment and is tolerant to moderate levels of salts and other pollutants near roadways and island beds. Its roots are not prone to surfacing, making it ideal for planting closer in proximity to buildings and parking areas than larger canopy trees that may cause problems over time. There are no known pests or diseases, and once established, the Katsura requires no special care other than supplemental watering during periods of prolonged drought. Perhaps the most sensory aspect of the Katsura, apart from its eye-catching color, is its aroma. Cooler fall weather brings out the colorful yellow, burgundy

and orange tints in the leaves, while providing the scents of cotton candy and brown sugar to the air nearby. Bernheim Arboretum has a 50-year-old specimen that draws comments from visitors each year due to its spicy fragrance. There are several forms of Katsura that are of great interest in the industry, including weeping forms, ‘Pendula’ and ‘Amazing Grace’. Both are terrific cultivars and remain smaller than the species, reaching 15' to 25' with a graceful, mounding habit, making them ideal specimen trees for the collector’s landscape. Katsura ‘Red Fox’ is also noteworthy with beautiful deep burgundy spring growth. Available as both single and multistemmed tree, the Katsura is a superb addition to the woodland garden or urban landscape. 2

News from the KDA

Kentucky Commissioner of Agriculture

From the

Dear friends, As your new Kentucky Commissioner of Agriculture, I understand the importance of the nursery and landscape industry to our Commonwealth’s economy. I also understand the struggles the industry has been through over the past several years with the downturn in the economy. With that said, Kentucky’s green industry in 2013 still generated $1.52 billion in sales, supporting 18,821 jobs! The Kentucky Department of Agriculture is committed to our continued support of the industry. If you are a Kentucky Proud member, you may be eligible for a Kentucky Proud Promotional Grant. It would reimburse up to half of eligible expenses for advertising, marketing and reaching consumers at the point of purchase to promote Kentucky Proud products with direct Kentucky farm impact. The maximum reimbursement is $12,000 in 12 months, based on 10% of direct Kentucky farm impact. For more information on this grant, visit: KYP_GrantApplication.pdf. Please know that my door is always open. If my staff or I can help you in any way, don’t hesitate to contact us. Best wishes on another successful year! Sincerely,

Commissioner of Agriculture Commonwealth of Kentucky
