Asclepias General Information
Asclepias, Whorled or Horsetail Milkweeds are best in sunny locations with sandy soils. Almost needle-like foliage appears in whorls of 3-6 at each node. Milkweed is a nectar source for Monarch butterflies and also a host plant for them to lay their eggs. Plant in groups to attract more butterflies.
Asclepias Plant Care
Low maintenance. Can be slow to establish but is long-lived once it takes hold. Late to emerge in the spring. If desired, divide and cut back in spring when new growth starts, being careful of long taproot. Be aware that Asclepias is slow to recover once moved or divided. Remove spent flowers to encourage rebloom and prevent self sowing. Allow some spent flowers from 2nd bloom to remain on plant to form ornamental fruit for late season interest.
