Regional Picks: Plants for Wet Soil – Northeast

Fine Gardening - Issue 136

1. Cinnamon Fern

Cinnamon Fern

Name: Osmunda cinnamomea

USDA Hardiness Zones: 4 to 8

Size: 3 feet tall and 2 feet wide

Conditions: Partial to full shade; moist, acidic soil

This tall, northeastern native fern forms large clumps of graceful, arching fronds. An attractive contrast appears in midseason when the shorter, cinnamon-colored fertile fronds spike up amid the green foliage. These rusty spikes are covered in fuzz, which hummingbirds readily use to line their nests in summer, and persist on the plant through winter. Fiddle­ heads from the cinnamon fern are edible but must be cooked.


2. Greenhead Coneflower

Greenhead Coneflower

Name: Rudbeckia laciniata

Zones: 3 to 9

Size: 5 to 10 feet tall and 3 feet wide

Conditions: Full sun to partial shade; moist soil

Yellow petals surround a thimble-shaped greenish center on this showy wildflower. The yellow color is softer than traditional black-eyed Susan (Rudbeckia fulgida and cvs., Zones 4–9), so it’s easier to find companions in the garden. Greenhead coneflower is tall but doesn’t require staking. Long blooming (summer through fall), it makes a great cut flower.


3. Bunchberry


Name: Cornus canadensis

Zones: 2 to 7

Size: 6 inches tall and indefinite spread

Conditions: Partial sun to full shade; moist, acidic soil

You can tell this deciduous ground cover is a member of the dogwood family just by looking at it. The star-shaped white flowers appear in early summer and have a sweet scent. The blooms are followed by clusters of shiny red berries, which are an excellent food source for birds. In fall, the foliage turns a brilliant red. Bunch­berry makes an excellent ground cover in wet spots as well as under evergreens; it just needs adequate water while it is first getting established.


4. American Cranberry

American Cranberry

Name: Vaccinium macrocarpon

Zones: 2 to 7

Size: 6 inches tall and indefinite spread

Conditions: Full sun; moist to wet, acidic soil

An evergreen shrub, American cranberry can be successfully used as a ground cover in wet areas or as an elegant accent along the edge of a pond. The tiny leaves line 8- to 10-inch-long vines that look like branches. The delicate pink flowers are barely noticeable in early summer, but you can’t miss the bright scarlet fruit that follow. Your cranberries will be larger than what you see sold in the grocery store. They ripen as the plant’s foliage turns purple in fall, and they taste sweeter after the first frost.
