Title: Companion plants for irises
Answered by: Nan Hampton
There are several of possibilities for companion plants for your iris, depending on whether they are growing in a flower bed or growing in a wet boggy area. Many native irises [e.g., Iris brevicaulis (zigzag iris) and Iris fulva (copper iris)] grow in marshy areas in the wild, but they also adapt to growing in traditional garden flower beds.
First, here are some suggestions for plants with contrasting color and foliage for a regular well-drained (but with moist soil) flowerbed:
Aquilegia canadensis (red columbine)
Asclepias tuberosa (butterfly milkweed)
Asclepias incarnata (swamp milkweed)
Stachys coccinea (scarlet hedgenettle)
Physostegia intermedia (slender false dragonhead)
If your irises are growing in a semi-aquatic or aquatic area, then here are other suggestions:
Marsilea macropoda (bigfoot waterclover)
Bacopa monnieri (herb of grace)
Hydrocotyle umbellata (manyflower marshpennywort)
Saururus cernuus (lizard's tail)
Pontederia cordata (pickerelweed)
