Butterfly Weed is a perennial plant native to Florida, as well as eastern North America. It can grow over 3 feet but tends to stay around 2ft. Around the 2nd or 3rd year, A. tuberosa will bloom clusters of yellow/orange flowers that attract butterflies/pollinators. Although the the larval host plant for the Queen and Monarch butterflies, A. tuberosa does not have high concentrations of the milky sap, making it a last choice for the Monarch to lay her eggs, if other milkweeds are around. Butterfly Weed prefers dry/sandy soil and full sun, and does very well, here in Central Florida. Butterflyweed can adapt to almost any Florida soil type, as long as its well draining. Save the well amended areas for the fruits and veggies. Butterflyweed needs regular watering throughout it's early days, but is very drought tolerant when established. Direct sow in the Fall to let the seeds over-winter for a Spring and Summer bloom. If planting seeds in the Spring or Summer, the seeds need 2-4 weeks of cold/wet stratification, and are only planted about 1/4in deep. The Butterflyweed makes a tap root up 4-6 inches long, that it will regrow from, year to year. Be aware of the large roots if transplanting.
