Tuberosa Milkweed

Asclepias tuberosa

Also known as 'Butterflyweed', it's a host plant to the Monarch, Queen and Soldier butterflies. When blooming, they get beautiful fire-orange flower clusters that attract bees, many butterfly species and your occasional hummingbird. Being a Florida Native, they are also highly drought tolerant once established.

How to care for Tuberosa Milkweed

Light. Full sun.

Water. Water regularly until it is established, which can take a while. After that it tolerates long dry periods. Soggy soil causes crown rot.

Soil and feeding. It grows in sand or loam, including poor, dry soil, at acidic to neutral pH. Good drainage is essential.

Size. Upright clumps about 2 ft tall and up to 1.5 ft wide.

Pruning. Deadhead spent flowers for more blooms. Remove seed pods before they split if you do not want seedlings.

Problems to watch. Aphids cluster at the tips; knock them off with a strong spray of water every 2–3 days for a week. Its deep taproot makes it hard to transplant.

Good to know. A Florida native and larval host for monarch, queen and soldier butterflies. The sap irritates skin and eyes, and eating the plant causes stomach upset; wear gloves and keep pets away.
