Nature Play:

Growing Curious Minds Through Outdoor Discovery How Huntsville Botanical Garden inspires curiosity, creativity and lifelong learning through nature.

By Rebecca Turk, VP of Learning & Public Engagement

Many adults remember childhood afternoons spent building forts, making mud pies, catching fireflies or racing leaves down a stream. Today, those simple moments of discovery often require more intention as busy schedules and technology compete for children’s attention.

As Huntsville continues to grow, so does the need for places where families can connect, explore and learn together outdoors. At Huntsville Botanical Garden, nature play is more than an activity—it’s a philosophy that shapes how children experience the Garden and how families create lasting memories.

Every youth education program, interactive landscape and future expansion is rooted in that philosophy: children learn best by exploring the natural world through curiosity, creativity and hands-on discovery.

Fall tasks and timely guidance for a healthy In The Garden home garden.

Spring tasks and timely guidance for a healthy home garden Fall is the perfect time to prepare your garden for the seasons ahead. Weed pressure is significantly lower than during the peak growing season, but winter weeds are beginning to germinate, so stay ahead of them with mechanical or chemical control methods.

Cool-season vegetables started in late summer can be planted in the landscape and harvested until hard freezes arrive later in the year. As warmseason turfgrass begins to go dormant, raise your mower blades and discontinue your fertilization schedule.

Fall is also one of the best times to plant trees, shrubs and perennials, as cooler temperatures and seasonal rainfall encourage strong root growth.

Even with regular rainfall, monitor new plantings and water as needed during dry spells to help them become established. If your houseplants have spent the summer outdoors, now is an ideal time to bring them inside. Similar indoor and outdoor temperatures during early fall make the transition easier and help reduce stress on the plants.

When many people picture a botanical garden, they imagine beautifully manicured flower beds bursting with seasonal color. While those formal display gardens are certainly part of the experience, they are only one piece of the story. At Huntsville Botanical Garden, every landscape is intentionally designed to serve a different purpose. Some spaces inspire beautiful home landscapes, others preserve important plant collections, some provide hands-on learning opportunities, and others showcase the natural beauty of North Alabama. Together, they fulfill one mission: connecting people to plants.

Gardens That Inspire One of the most recognizable types of public gardens is the ornamental display garden. These spaces are designed to captivate visitors through beautiful plant combinations, seasonal color and thoughtful design.

Many are influenced by English landscape gardens, which emphasize flowing lines, diverse plantings, trees, shrubs and perennials to create landscapes that feel both natural and inviting. Unlike formal European gardens that rely on strict symmetry and geometric

layouts, English-inspired gardens embrace color, texture and seasonal change.

Some of the best examples at Huntsville Botanical Garden include the Floral Promenade, the Four Seasons Garden and the landscapes surrounding the Propst Guest Center. While visitors may not recreate these spaces exactly, they offer endless inspiration for color combinations, plant pairings and design ideas that can be adapted for home gardens.

Celebrating North Alabama’s Natural Beauty Not every space at Huntsville Botanical Garden is highly manicured—and that’s intentional.

These landscapes demonstrate the beauty and ecological value of native plants while supporting birds, pollinators, and other wildlife. They also show visitors how native species can be incorporated into home landscapes to create beautiful gardens that benefit local ecosystems.

More Than One Kind of Garden A successful botanical garden is not defined by a single style of

protecting native ecosystems.

The contrast between cultivated gardens, educational spaces, living collections, and natural areas is intentional. Together, they create a richer experience than any one garden style could provide on its own.

The next time you visit Huntsville Botanical Garden, look beyond the flowers. Each garden tells a story, and every path offers a new way to connect with plants.

What Determines Autumn Leaf Color?

By Vânia Pereira, Ph.D., Curator of Living Collections

As temperatures begin to decrease and signs of autumn appear, social media fills with photographs of yellow, orange and red trees. Yet here in North Alabama, many trees remain green while autumn appears well underway elsewhere. This often leads to a common question: Why haven’t the leaves changed yet?

The answer lies in an elegant and complex combination of plant biology, chemistry and weather. Leaves do not simply “die” and change color. Instead, trees undergo a carefully regulated seasonal transition that allows them to conserve valuable nutrients before winter dormancy. The timing and brilliance of autumn color depend on everything from daylight and temperature to rainfall and tree species. Understanding this process helps explain not only why leaves change color, but also why North Alabama’s fall display often arrives weeks later than in more northern states.

primarily blue and red wavelengths of sunlight while reflecting green light, which is why healthy leaves appear green.

As long as environmental conditions remain favorable, trees continually produce new chlorophyll to replace older molecules damaged by sunlight.

This constant renewal keeps leaves green throughout the growing season and allows trees to maximize energy production.

Although chlorophyll dominates what we see, it is not the only pigment present in leaves. Other pigments remain there all summer, but their colors stay hidden beneath chlorophyll’s vibrant green.

The Chemistry Behind Fall Color As summer gives way to autumn, trees begin preparing for winter dormancy. One of the most important environmental cues is day length, or photoperiod. The shortening days of autumn provide trees with a reliable signal that winter is approaching. In response, many deciduous* trees begin shutting down photosynthesis.

Moisture also plays an important role. Trees receiving adequate rainfall generally maintain healthier foliage capable of producing stronger fall color. By contrast, prolonged drought may cause leaves to become stressed, turn brown prematurely or fall before vibrant colors develop. Early hard freezes can abruptly damage leaf tissues, shortening the color season before pigments fully develop.

“As the green pigment disappears, other pigments become visible. This color change is an active, highly regulated physiological process that helps trees prepare for winter.”

As a result, peak fall color in the Huntsville area frequently occurs from late October through midNovember. Rather than producing a brief burst of color, North Alabama often experiences an extended autumn season that unfolds gradually over several weeks.

Why Trees Change at Different Times Not all tree species respond to autumn in the same way. Each species has evolved unique physiological strategies that determine when leaves begin senescing—the natural aging process that precedes leaf drop.

More Than a Vegetable Garden The Demonstration Vegetable Garden at Huntsville Botanical Garden teaches, inspires and gives back—one growing season at a time.

By Cameron Oldham, Cultivated Areas Supervisor

Growing Knowledge The Demonstration Vegetable Garden inspires and educates home gardeners by showcasing practical ways to grow food successfully in our region. Rather than focusing on a single gardening method, the garden demonstrates several approaches visitors can adapt for their own landscapes.

Traditional row gardens, raised beds, square-foot gardens and other growing methods offer advantages depending on available space, budget and gardening goals. By seeing these techniques in action, visitors discover which methods work best in yards.

VOLUME 7, ISSUE 4

Many visitors walk through the Demonstration Vegetable Garden (DVG) and see rows of tomatoes, peppers, beans and seasonal crops. What they may not realize is that the garden serves multiple purposes. It is a teaching space, a testing ground for gardening techniques, a showcase of vegetables that thrive in North Alabama and a source of fresh produce for the community. Behind every harvest is a dedicated team of volunteers who bring the garden to life throughout the growing season.

Education is at the heart of the garden’s mission.

Visitors often ask which vegetables grow well in North Alabama, which varieties perform best and how to make the most of their growing space. The Demonstration Vegetable Garden helps answer those questions through real-world examples.

Throughout the season, the garden showcases vegetables commonly grown in the Southeast while also evaluating new varieties and seed trials to determine how they perform in our climate.

Volunteers rely on recommendations from the Alabama Cooperative Extension System,

the Southeastern U.S. Vegetable Crop Handbook and other trusted horticultural resources when selecting crops and varieties.

“For your own garden, choose vegetables that you and your family like to eat.”

– Susan Parker, Lead DVG Volunteer and Extension Master Gardener

Garden planning can seem overwhelming for both new and experienced gardeners, but Susan Parker’s advice reminds us that gardening starts with simple choices. The Demonstration Vegetable Garden follows that philosophy while introducing visitors to unique heirloom varieties and new plants worth exploring.

Each season provides opportunities to learn what grows well, experiment with new varieties and discover something different.

Learning By Doing The garden reminds visitors that successful gardening begins with simple steps. Choosing a sunny location,

paying attention to soil and moisture needs, and learning from both successes and setbacks all contribute to becoming a better gardener.

“Do not overthink or think all must be perfect just to start. Sow those seeds and dig the holes for the transplants you have already purchased.”

– Susan Parker Whether you’re planting your first tomato or expanding an established vegetable patch, the Demonstration Vegetable Garden shows that gardening is a continual learning experience.

Powered By Volunteers The Demonstration Vegetable Garden thrives because of its volunteers. Many bring decades of gardening experience to the space, including members of the Master Gardeners of North Alabama.

students and fellow volunteers. Their willingness to answer questions and demonstrate good gardening practices transforms the garden into an inviting learning environment.

Parker has led the garden for many years and coordinates nearly every aspect of its operation. She volunteers because the Demonstration Vegetable Garden provides opportunities to demonstrate, educate and share gardening experiences with the community. Her enthusiasm and knowledge help create a welcoming atmosphere where gardeners of all experience levels feel comfortable asking questions and learning alongside one another.

The Demonstration Vegetable Garden also models sustainable gardening practices. Composting, physical pest management and thoughtful garden planning help maintain the space while reducing unnecessary waste and chemical inputs. These demonstrations give visitors practical ideas they can adapt in their own gardens, whether they grow vegetables in a backyard, raised bed or small home garden.

“After retiring and moving to the area in 2024, I began volunteering at HBG, and it has been an ideal experience.

The Garden has enhanced my retirement with purpose, opportunities to learn, valuable friendships, and the joy of contributing to our community. What I give through volunteer service is returned through the fulfillment and connection I have found here.”
