Delaware landscaping FAQ

What climate zone is Delaware for plants?
Delaware spans USDA zones 7a (northern DE including Wilmington and Dover) to 7b (coastal areas including Rehoboth Beach and the southern coast). Zone 7a means average minimum temperatures of 0-5°F; zone 7b means 5-10°F minimums. This makes Delaware quite mild for the Mid-Atlantic — you can grow many plants typically associated with Virginia or even the upper South. The coastal zone 7b areas have very mild winters relative to inland Mid-Atlantic states.
What are the best native plants for Delaware landscaping?
Top Delaware native plants: Trees — American holly (state tree), tulip poplar, sweetgum, American beech, serviceberry, redbud. Shrubs — inkberry holly, wax myrtle, Virginia sweetspire, oakleaf hydrangea, buttonbush, native azaleas. Perennials — cardinal flower, joe-pye weed, ironweed, wild bergamot, black-eyed Susan, swamp rose mallow. Grasses — switchgrass, little bluestem, river oats. Coastal specifics — bayberry, beach plum, beach grass, seaside goldenrod, saltmeadow cordgrass.
How do I landscape a Delaware beach property?
Beach property landscaping in Delaware requires salt-tolerant, drought-tolerant natives: (1) First 100 ft from ocean: beach grass, native dune sedge, beach plum, rugosa rose — nothing else will survive salt spray. (2) 100-300 ft: bayberry, wax myrtle, seaside goldenrod, native grasses. (3) 300+ ft: wider selection including native hollies, red cedar, and native groundcovers. Use sand-based soil amendments, avoid clay-heavy soils near coast, and mulch with gravel/stone rather than wood chips (which blow away). Never remove existing dune vegetation.
What trees are recommended for small Delaware yards?
Small trees for DE yards (under 25 ft): serviceberry (multi-season — spring flowers, summer berries, fall color), redbud (April magenta blooms), American holly (evergreen year-round interest), native plum (spring flowers, edible fruit), native fringe tree (May white fringy flowers), and native witch hazel (winter blooms, can be kept small). All are Delaware natives that support wildlife. For very small yards (under 50 ft wide), consider multi-stem shrubs like native hazelnut or native spicebush as tree substitutes.
How do I deal with Delaware's clay soil?
Clay soils are common in northern and central Delaware. Improvements: (1) Raise beds 8-12" for vegetables. (2) Amend with compost (4-6" tilled in) for shrub and perennial beds. (3) Choose clay-tolerant plants: native swamp rose mallow, Joe-Pye weed, buttonbush, cardinal flower, and most oaks. (4) Install French drains in chronically wet areas. (5) Avoid compacting wet clay — install stepping stones or mulched paths. (6) Soil test first — most DE clay is near-neutral pH (6.5-7.0), good for most plants.
What is Delaware's most famous garden?
Delaware's Longwood Gardens (Kennett Square, PA, just over the border) is one of the world's great gardens. Closer to home, Winterthur Museum and Garden in Wilmington is a premier example of American naturalistic garden design — Henry Francis du Pont's 1,000-acre estate features the famous Azalea Woods walk in April-May. Mount Cuba Center in Hockessin specializes in native plants of the Piedmont and is a must-visit resource for Delaware gardeners seeking native plant inspiration.
