“Heart Leaf Milkweed”

Gorgeous, large, loose umbels bear rich, shiny violet–purple petals sexily contrasted by creamy-white “horns”. How pretty! Plus it has rich purple stems, purple spherical buds & fabulous, large, bluish waxy leaves. To 2’ tall & 3’ across- it blooms in late Spring thru Summer & of course, is highly important as a food source & larval host (queen larval too!) to our beloved western Monarch butterflies. Native to much of California , Nevada, & Oregon (including the shore line of Martinez – for you locals), long-lived & carefree “Heartleaf Milkweed” is highly drought tolerant & needs no Summer water once established. It’ll go deciduous sometime after bloom but reliably reappears each Spring. Excellent for out-of–hose- reach areas, parking strips, CA Native or dry gardens. It's not fussy about soil but does appreciate good drainage.
NOTE: Due to CA agricultural regulations, we are required to treat all Asclepias plants with BT, a non-toxic and naturally occurring biological larvicide, to help combat the Light Brown Apple Moth (LBAM). Effects can last up to 2 weeks after application. If you are planning to introduce Monarch caterpillars to this plant, we recommend letting it establish for one season before doing so to ensure it is large enough to provide sufficient food.
