Asclepias cordifolia is a species of milkweed commonly called heart-leaf milkweed or purple milkweed (a common name shared with another milkweed, Asclepias purpurascens). It is native to the western United States (California, Nevada, Oregon). Heart-leaf milkweed was valued by the Native American Miwok tribe for its stems, which they dried and processed into string and rope.
Heart-leaf milkweed is a perennial that grows to a height of 24", 60cm, with dark red-purple flowers. The large opposite leaves are cordate, or heart-shaped. The plant grows in open or shaded woodland, often on rocky slopes and in mixed coniferous forest. The milkweeds are named for the milky sap which exudes from the plant's stem. It blooms from May to July.
Monarch butterfly caterpillars are commonly found on all the milkweeds, including the heart-leaf milkweed. Even after the caterpillar has metamorphosed into a butterfly, the alkaloids they ingest from the plant are retained in the butterfly, making it unpalatable to predators.
Seeds are very rare and in limited supply!

I got these pretty quickly and in perfect order. I can't wait to see what they look like once I plant them. I have another colour and they were so pretty I had to try these. I have used this seller a few times now with great success, and will again. Everything I have ordered has been of good quality!

I happened across Ferri Seeds website when I Googled a particular plant I’d been looking for. I was impressed by their selection of all types of seeds and their good product descriptions along with detailed germination instructions. I found the site and ordered on a Saturday. On Sunday I got a notice that my order had been shipped! The seeds were in my P.O. box on Friday. Such amazing service. It’s too early to comment on germination rates — I’ve just started the stratification process today.

Ferri Seeds offered a hard to find seed on their website. I placed the order but had questions about product and delivery. Customer service contacted me right away. My questions were answered right away. I was kept updated on delivery progress. The seeds were exactly what I wanted. My husband is a very serious gardener. I will do more business with Ferri.
