What with more than twice our normal rainfall the several weeks, we have probable found places in our landscape where water pools or where the soil stays wet.

I thought about this recently when at Cardno Native Plant Nursery in Walkerton, Indiana, for the annual open house. Among the programs was one on native plants for the landscape, which included those for rain gardens and swales.

We may not have a rain garden or swale, but we may have wetter areas of the landscape where plants struggle. Here are some recommendations from Cardno, along with a few others, for native plants that can handle a moist environment.

For sunny areas:

  • Gayfeather (Liatris spicata) gets 2-4 feet tall and has spikes of purple flowers in mid summer. Butterflies and bees like this plant. Tolerates what’s called dry down, when the area drains the soil dries out. Gayfeather is a lovely addition to cut flower arrangements, too.
  • Cardinal flower (Lobelia cardinalis) has vivid red flowers that hummingbirds love. Gets 1-4 feet tall, and does best in areas that stay moist. Blooms in early summer. Tolerates rabbits and deer.
  • Blue flag iris ( versicolor or I. virginica) has slightly fragrant blooms in late spring and early summer. Gets about 2 feet tall and wide. Prefers rich, organic soil. Tolerates dry down and deer.
  • Swamp milkweed (Asclepias incarnata) has fragrant white, mauve or pink flowers atop 4-5 foot tall stems in mid to late summer. Supports monarch butterfly caterpillars and tolerates deer.

For shady areas:

  • Great blue lobelia (Lobelia siphilitica) tolerates full sun but seems to do better when given a little shade. It gets 2-3 feet tall and has stalks of blue flowers mid summer to fall.
  • False Solomon’s seal (Smilacina racemosa or Maianthemum racemosum) has white or cream colored flower on arched stems in spring. In fall, it sports red berries, which are great for use in flower arrangements. The plant gets about 2 feet tall.
