Glens Falls sits in USDA hardiness zone 5b, which means winter temperatures can drop to -15°F to -10°F. This climate is perfect for hardy perennials and shrubs that thrive in cold winters and moderate summers. The key to success is choosing plants adapted to these conditions.
Perennials are the backbone of any Glens Falls garden. These hardy plants return year after year:
Purple coneflowers are a Glens Falls favorite. They bloom from mid-summer through fall, attract butterflies, and require minimal maintenance. Plant them in full sun with well-draining soil. They're drought-tolerant once established, making them perfect for busy gardeners.
These cheerful yellow flowers bloom reliably from July through September. They're incredibly hardy, deer-resistant, and thrive in poor soil. Black-eyed Susans pair beautifully with coneflowers for a classic cottage garden look.
Daylilies are nearly indestructible and come in dozens of colors. They tolerate partial shade, poor soil, and drought. In Glens Falls, they bloom from June through August and require almost no maintenance once established.
Perfect for shaded areas under trees, hostas add texture and color to your Glens Falls garden. They're cold-hardy, deer-resistant (mostly), and come in variegated and solid colors. Plant them in moist, well-draining soil.
Feather reed grass, fountain grass, and miscanthus add movement and winter interest to gardens. They're hardy, drought-tolerant, and provide beautiful texture throughout the seasons. Cut them back in early spring before new growth appears.
Lilacs are a Glens Falls tradition. They bloom reliably in spring with fragrant purple, pink, or white flowers. Plant them in full sun and prune after flowering to maintain shape. They're extremely hardy and long-lived.
Panicle hydrangeas are the most cold-hardy variety for zone 5b. They bloom from July through September with large flower clusters that turn pink and bronze in fall. Plant them in full sun to part shade with moist soil.
Spireas are compact shrubs with delicate flowers. Bridal wreath spirea blooms in spring, while summer spireas flower from June through August. They're extremely hardy and require minimal pruning.
Plant tulips, daffodils, and crocuses in fall (September-October) for early spring color. These bulbs are hardy in Glens Falls and provide welcome color after winter. Daffodils are deer-resistant, making them a great choice.
Spring (April-May) and fall (September-October) are ideal planting times in Glens Falls. Avoid planting during summer heat or winter frost. Spring planting gives plants time to establish before winter, while fall planting allows root development before spring growth.
Most Glens Falls gardens benefit from adding compost or quality topsoil. Amend heavy clay soil with organic matter to improve drainage. Well-draining soil prevents root rot and fungal diseases in our humid summers.
New plants need regular watering their first season. Once established, most perennials are drought-tolerant. Water deeply but less frequently to encourage deep root growth. Mulch around plants to retain moisture and regulate soil temperature.
In Glens Falls, mulch helps protect plant roots from extreme cold. Apply 2-3 inches of mulch around plants in late fall. Remove excess mulch in spring to prevent rot and allow new growth.
