Asclepias incarnata - Swamp Milkweed
Asclepias incarnate is also called Swamp or Rose Milkweed and is an essential plant for monarch butterflies & caterpillars as well as many other pollinators. It is best grown in moist to wet soils in full sun, but it also does perfectly well in average well-drained garden soil provided it has regular moisture. The 3'-5' plants form stately clumps with upright stems and long narrow leaves. Price is for a 4.5" Quart Pot. Available after 4/15.
(note Asclepias incarnata 'Cinderella' (a nativar) is also available at the nursery in gallon pots for 11.95)
