Cultivar of a North American native species; the base species, Asclepias incarnata, is native to wet meadows, marshes, and streambanks across eastern and central North America. While the white flower color is a horticultural selection, the plant retains the full ecological value of the species.
WILDLIFE & INSECTS
Butterflies
- A host plant for Monarch caterpillars, and an important nectar source for adults. It also attracts Queen, Swallowtail, and Skipper butterflies.
Bees
- Highly attractive to bumblebees, leafcutter bees, and other native pollinators seeking deep, nectar rich flowers.
Other Insects
- Supports milkweed beetles, aphids, and predatory wasps, contributing to garden balance and food web health.
- The white blooms may be even more visible to pollinators in low light conditions, enhancing late day foraging.
SPACING & LANDSCAPE USE
Spacing Recommendations
- Plant 2 - 3 ft apart to allow upright clumps to mature and attract pollinators.
Landscape Placement
- Ideal for rain gardens, pollinator meadows, pond margins, and moist naturalistic borders. Use as a vertical accent in sunny or semi shaded areas with rich soils.
