Milkweed for monarchs
-
Asclepias fascicularis
Monarch butterfly on Asclepius fascicularisThis California native milkweed is critical in the life-cycle of the monarch butterfly whose larvae feed on the foliage. It is a virtually carefree perennial that has light green narrow leaves on 3' stalks, with clusters of pinkish white flowers in summer. It is dormant in winter. Milkweed performs best in full sun with well draining, moist or dry soil. It tolerates clay soil, flooding, and drought. It is an outstanding choice for natural and butterfly gardens.
Milkweed is poisonous if taken internally and considered invasive in some areas.
