Click for larger photograph.Introduction: Butterfly Weed is spectacular in almost every way. Native. Non-invasive. Easy to grow. Butterfly Weed is irresistible to butterflies. Excellent as a dried flower and in arrangements. Both orange and white varieties are available. Butterfly Weed is a food source for Monarch Butterfly caterpillars as well as many other species of butterflies. Considering milkweed is the sole source of food for Monarch Caterpillars, and considering that urban and suburban development is eroding naturally occurring habitats, planting Butterfly Weed is a way to help.

Experts Know: One of the great perennials, Butterfly Weed emerges late in spring; do not disturb soil around the dormant plant. Due to the long taproot, Butterfly Weed is difficult to transplant. Once established, leave in place.Let the pods that develop after flowering mature, as new seeds will be dispersed.

Pests: Aphids may be an issue, but they generally won’t do lasting damage to the plant. Considering Butterfly Weed is a host for numerous butterflies, caterpillars, bees, and other insects, it would be irresponsible to use sprays to control Aphids should they appear. I have grown Butterfly Weed for years, and the best thing to do is not hand-wring over it. This plant is tough.
