Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Plants for wet soils in North Carolina
Answered by: Nan Hampton

QUESTION:

I'm looking for evergreen plants (shrubs or ground cover)that will tolerate wet conditions for the zone 8 area of North Carolina. The local garden centers here do not stock these types of plants, even though much of the soil around here is prone to wetness from overflowing streams, lots of rain, topography, etc! Thank you.

ANSWER:

Here are various evergreen plants that tolerate, or require, wet soils in North Carolina:

TREES/SHRUBS:

Chamaedaphne calyculata (leatherleaf)

Chamaecyparis thyoides (Atlantic white cedar)

Ilex glabra (inkberry)

Morella cerifera (wax myrtle)

Rhododendron maximum (great laurel)

Vaccinium macrocarpon (cranberry)

VARIOUS HERBACEOUS PLANTS:

Adiantum capillus-veneris (common maidenhair) is evergreen in mild winters.

Carex cherokeensis (Cherokee sedge)

Eleocharis montevidensis (sand spikerush)

Equisetum hyemale (scouringrush horsetail)

Gelsemium rankinii (Rankin's trumpetflower) and here are photos and more information.

Hydrocotyle umbellata (manyflower marshpennywort)

Maianthemum canadense (Canada mayflower)

Rhynchospora colorata (starrush whitetop)
