butterfly weed (asclepias tuberosa) which I have had on house south side for 12 years and has done wonderfully except this year it came up, about 10 inches, then withered and died. Too much rain? Some bug? Any suggestions?
Asclepias tuberosa, butterfly weed is a native prairie plant that tolerates poor dry soil and is drought tolerant. It grows best in full sun. Well draining soil is essential especially in the winter. It is late to emerge in the spring and is usually long lived once established.
This spring has been cool and wet and if the drainage was not ideal the plant may have declined. Check the soil moisture/drainage in the area. Also, mulch should be no thicker than two inches and kept away from the base of the plants.
