December Garden To-Do List

Spotlight Special Strawberry Purple Wonder™

The first ever purple strawberry was introduced last spring at the Philadelphia Flower Show. The color and flavor is a breeding breakthrough. Incredible purple fruits are extra sweet and delicious. June-bearing plants are tidy and attractive, with beautiful fully-lobed, bright green leaves. Expect bountiful fresh pickings in summer. Because the plants do not produce many runners, they are particularly appropriate for container gardening. A one-of-a-kind strawberry for discriminating berry aficionados. Bred by Dr. Courtney Weber at Cornell University. Patent pending. “Purple Wonder is sweet and aromatic, with outstanding strawberry flavor,” said Courtney Weber, Cornell small fruits breeder and associate professor of horticulture. “But the color is something you won’t be able to find in any grocery store. “The color develops all the way through the fruit, which might surprise consumers accustomed to supermarket fruit with color mostly on the surface,” said Weber. “And letting the fruit ripen on the plant just makes the berries sweeter.” The berries and their purple juice can also be used to produce deep colored preserves and strawberry wine, and Purple Wonder’s high antioxidant content gives them a healthy boost. Available exclusively through


Here is our comprehensive garden task list for gardens in the greater DC metro region for December 16-January 15. Your additions to this list are most welcome: • Keep watering your poinsettias and give them plenty of light. Ensure they are away from drafts and that the pots drain freely. • Last chance to plant bulbs or if you have waited until the ground is frozen, pot them up for forcing indoors. • Gather holiday greens. Some, like holly and boxwood, benefit from being pruned by growing thicker. • Feed birds and provide them with a fresh water source. • Check houseplants and any plants you brought indoors for the winter, for insects. • Provide some special protection to tender or early flowering plants like Camellias. • Stake newly planted large trees or shrubs to protect them from winter winds. • Check any summer/tropical bulbs, corms, tubers and bare-root plants in storage for rot or desiccation. • Apply scale and dormant oil treatment to evergreens. • Spread ashes from wood fires on your vegetable beds. • Keep succulents and cacti on the dry side. • Water your cut Christmas tree daily. • Gently remove layers of snow from evergreens with a broom. • Start organizing your pile of incoming garden catalogs. • Keep an eye out for bark damage from rabbits and deer. • Spray broadleaf evergreens with anti-desiccant to prevent dehydration. • Use the branches from your Christmas tree as bedding mulch or as a wind-break. • Keep watering newly planted trees and shrubs as needed. • Cover strawberry beds with straw or pine needles. • Prune stone fruit trees like cherries, plums, and peaches. • Clean, sharpen, and store your garden tools. • Reduce fertilizing of indoor plants (except Cyclamen). • Set up a humidifier for indoor plants or at least place them in pebble trays. • Continue to rotate houseplants to promote even growth. • Attend a local garden club meeting. • Start new indoor plants from cuttings -- try an easy one such as violets. • Check the plants under tall evergreens and under the eaves of the house to see that they have sufficient moisture. • Weed. Weed. Weed. • Pick a budding gardener on your gift list to give some inspirational garden books and magazines then watch them blossom. • Store your fertilizer and seeds in rodent-proof containers. • Do any filling and grading around your yard. The soil will settle during the winter months. • Vent cold frames on sunny days. • Avoid walking in frozen planting beds. • Remove and destroy gypsy moth egg masses. • Clean your gutters. • Prune maples, dogwoods, birch, elm, and walnut -- if needed. • Bonus Tip: Some alternatives to de-icing salts include sand, beet juice sugars, light gravel (grit), or non-clumping kitty litter. Using de-icing salts around driveways and sidewalks can harm your garden plants and turf. Have a wonderful holiday season!

This year, we are holding dual Seed Exchanges one week apart on opposite sides of the Beltway. We urge you to attend the one closest to you. One exchange will be held in the Visitor’s Center Auditorium of the Brookside Gardens, 1800 Glenallan Ave., Wheaton, MD. The other will be at Green Spring Gardens 4603 Green Spring Road Alexandria, VA.

Washington Gardener Magazine’s 8th Annual

Seed Exchange Details

If You Have Seeds to Bring and Swap

Please package them in resealable plastic zipper or wax sandwich baggies. Put an average of 20 seeds per baggy — more for small seeds like cleome, fewer for large seeds like acorns. Then label each baggy with a white sticker (such as Avery standard 5160 address label sheets) giving all the information you have on the seeds. If known, include the plant's common and scientific names; its soil, sun, and watering needs; and, its origins — where and when you collected the seeds. If you don't know all the information, that's okay, just try to provide as much as you can. Yes, you can bring unused or opened commercial seed packs also.

What If I Don't Have Any Seeds to Swap?

Come anyway! Even if you don’t have any seeds to trade, you are welcome to attend! We'll have plenty of extra seed contributions on hand and many attendees will be there just to learn, network, and prepare for next year's seed collecting.

Education Program

from each of the category tables (if desired). After the initial seed swap is complete, attendees are free to take any of the left over seeds and to trade seeds with each other. Dividing of packets is encouraged and extra baggies with labels will be on hand for that purpose.


What Types of Seeds?

Expert speakers from the local gardening community will give short talks on seed collection and propagation tips. There will be ample time for individual Q&A throughout the program with the featured speakers, and invited experts as well. (Note: This schedule is subject to change.) 12:00-12:30 Registration check-in 12:30-12:40 Introductions 12:40-1:20 Gardening talk 1:20-1:40 Gardening talk 1:40-2:00 Gardening talk 2:00-2:15 Snack break and room reset 2:15-2:30 Seed swap preview time 2:30-3:00 Seed swap 3:00-3:30 Photo Contest winners 3:30-4:00 Door prizes and closing talk

How Do We Swap?

As you check-in, staff will collect your seeds and place them at the appropriate seed category tables. You will be assigned a random seed swap number. There will be a short period for attendees to preview all the seeds brought in and available for swapping. Then, you will be called in by your number to pick a seed pack

Seed swap categories will include natives, edibles, herbs, exotics, annuals, perennials, and woodies (trees/shrubs). If you can presort your seeds in advance into whichever of these seven major categories fits best, that would help us speed up the process on the swap day.

Door Prizes! Goodie Bags!

All attendees will receive a goodie bag at the seed swap. The bags include seeds, publications, and garden items donated by our sponsors. In addition, we have some incredible door prizes to give away especially for area gardeners. If your organization would like to contribute seeds or garden-related products for the goodie bags and door prizes, please contact Kathy Jentz at 301.588.6894 by January 21.

Holly Shrubs and Trees

The Versatile Landscape Beauty by Kathy Jentz

The Holly is one of the most adaptable plants for your landscape. It is a good filler in a shady areas. It attracts birds to your garden. It provides color in the gray winter. It can make a great property line screen or as a trimmed hedge. It can be used as a specimen tree or focal point in your yard. With so many different kinds and new cultivars being constantly introduced, the Holly is a true versatile beauty. If you are choosing a holly for your home landscape, “Natives are among the best choices,” says Bill Kuhl, proprietor of McLean Nurseries on Satyr Hill Road in Baltimore, MD. McLean is a holly lover’s paradise. Kuhl bought the nursery in 1972 from Helen McLean, who the ‘Miss Helen’ holly was named for. Her husband, Stewart McLean, started the nursery in 1946. He recommends the American Hollies (Ilex opaca). Many cultivars originated in Maryland including the aforementioned ‘Miss Helen’ and ‘Satyr Hill’, an famous introduction of McLean Nurseries. “Our holly ‘Satyr Hill’ has got a lot of attention in the nursery world as a fine holly to grow,” Says Kuhl. “It has had very favorable response and is grown in nurseries in North Carolina and New Jersey.” It is especially suited to our Mid-Atlantic climate. Winterberry (Ilex verticillata) is also very popular. Kuhl notes that the aptly named ‘Maryland Beauty’ winterberry does very well for gardeners here. “It is nice because they hold the fruit well into the winter time,” Kuhl explains. McLean Nurseries sells holly plants, but also does a great business in cut greens for the holidays. Kuhl recommends using cut Winterberry branches for simple outdoor seasonal décor. “Just stick them in an outside urn, window box, or planter and they make a nice sculptural display and lasting for several weeks,” he explains. When purchasing new hollies for your home landscape, don’t plant them too deep and don’t plant it right next to the house. Give it space to fill out properly. Know enough about the particular variety to choose the right plant for right location. Kuhl commented, “I just visited a private 6

home in northern Baltimore County with several mature ‘Miss Helen’ hollies which had been growing there for 3035 year. They are doing beautifully and are all in the 20foot range.” When caring for your new hollies, be sure they have adequate water, especially when young. Apply just 2-3 inches of mulch – too much mulch can block off air to the roots and suffocate them. In addition, you don’t want tall grass growing up either inside or at the drip line as it will out-compete the holly’s shallow feeder roots and cause it to decline. If you are growing hollies to enjoy the berries, be aware that Robins love to devour them — which is fine, unless you had planned to use those berries in cut arrangements. Kuhl says the flocks of Robins stay all year long now, whereas a decade ago that was not the case. They generally do not strip the berries until after the holiday season in any case. Despite their deer-resistant reputation, hollies can also suffer extensive deer damage. The new leaf growth and lower branches are nibbled on. The deer rub on the trunks and tear up branches and bark. “You can protect them by fencing or other barriers until the young plant are large enough to withstand the deer browsing and molesting,” instructs Kuhl. “Watch out for vines getting in there,” cautions Kuhl. “As your hollies mature some vines can get inside them and cause damage. Keep an eye out for them and get them out before they get too big.” The biggest complaint that holly owners have is that they produce no berries. To produce a good crop, you must have both female and male hollies in close proximity and they must bloom at the same time. “People get confused because some female holly cultivars have male names,” explains Kuhl. “Females have berries and males have the pollen — preferably of the same species. You need to be a bit more careful with hybrid selection, especially with Winterberries. Some are late bloomers and need to be matched together.” If you are fortunate enough to be near some neighbors with established male hollies or where they are growing wild, then you can just purchase a few female hollies of your choice. Otherwise, you need to purchase at least one male holly for every 10 females. “It can be complicated,” comments Kuhl. “Plan it out first — talk to your local nurserymen, master gardener, or garden center.” For more information on growing hollies, visit the Holly Society of America’s web site at or consult the excellent book, Hollies – The Genus Ilex by Fred C. Galle (Timber Press). Kathy Jentz is editor of Washington Gardener Magazine.

Magazine Excerpt: Gunston Hall: Home of George Mason by Cheval Force Opp

Driving the 30 minutes to George Mason’s Gunston Hall, I enjoyed watching the urban landscape of highways and shopping malls ease into meadows and woods. The Mason Plantation was the center of a small universe for his close family. Mason; his wife, Ann Eilbeck Mason; their children; and nearly 100 slaves all depended on the plantation for their necessities. Like others in that time, the plantation’s site was chosen in no small measure for access to the Potomac River, since the poor roads made land travel time-consuming and uncomfortable. Had George Mason and his family traveled the 22 miles to visit me in Dunn Loring, VA, the trip would have taken the better part of their day. Of course, since George Mason IV is considered one of our colonial “Founding Fathers,” I would have done the courteous thing and put him, his wife, and nine kids up for the night, along with their driver, servants, and horses! Along with Monticello and Mt. Vernon, Gunston Hall’s landscape was famous in the 18th-century. Unlike Monticello and Mt. Vernon, conservators do not have the advantage of any surviving garden plans. So, without documentation, what guides restoration? Over the last 10 years, researchers have uncovered the original elements of Mason’s vision using archaeology. Supporting their investigations are the writings of George’s son, John Mason. John in his later years wrote “Recollections” describing the plantation remembered from childhood. Like his contemporary, George Washington, Mason was a surveyor and this linear thinking is reflected in the layout of his landscape and house situated on a bluff overlooking the Potomac. His plan fixes the mansion as the dominant element within a formal structure of roads, walkways, gardens, and trees. A twelve-foot-wide carriage road leads straight away from the Palladian...
