— Why this matters
Native Plants for Zone 4b: A Working List — and why it matters in Vermont.
Most planting plans in Vermont are written from regional ‘Northeast’ lists that include zone 5, 6, and 7 species — half of which die in our winters. This is the curated short list of plants we use repeatedly because they actually thrive in zone 4b, on Chittenden County soils, with the wildlife we share the place with.

— Frequently asked
What clients want to know.
Is zone 4b really that different from zone 5?
Yes. The bottom of zone 4b is -25°F; the bottom of zone 5a is -20°F. Five degrees doesn’t sound like much, but it determines whether a plant lives or dies in a hard winter. We’ve seen plants rated ‘zone 5 with protection’ fail in their second Vermont winter even with mulch and burlap.
Do you use only natives?
About 60-70% native species in most plans. Cultivars and well-behaved exotics have a place — particularly for specific design goals (autumn color, long bloom periods, structural form). But natives are the foundation of everything we do.
What about pollinators specifically?
Continuous-bloom strategy from April (bloodroot, wild columbine) through October (asters, goldenrod, eutrochium). Specifically called-out plants for native bees, monarchs, hummingbirds, and the broader pollinator community. We count documented pollinator species in our gardens — typically 12-20 native bee species in established plantings.
What about deer pressure?
Significant in Chittenden County. Our deer-resistant palette: alliums, salvias, lavender, ornamental grasses, ferns, baptisia, monarda, sedums, achillea, peony. Deer-loved (avoid in unfenced areas): hostas, day lilies, tulips, most of the ‘easy’ cottage garden palette.
Where do you source plants?
Vermont nurseries first — Bagley Pond Perennials (Pittsford), Walker Farm (Dummerston), Greenheart Garden (Williston), Claussen’s (Colchester for natives). Out-of-state for specific items only. Plants grown in Vermont conditions perform better than southern-grown stock.
What if I want plants from a Pinterest board?
We’ll evaluate them honestly. Most Pinterest ‘beautiful garden’ images are from zone 6 or 7 climates with very different growing conditions. We’ll tell you which plants on your wish list will work in Chittenden County and which will disappoint. Then we’ll suggest substitutions that achieve the same visual goal with plants that actually live.
