Arizona milkweed (Asclepias angustifolia) - 75 seeds
Native only to the state of Arizona, this species of milkweed is found in arroyos, canyons, along stream beds, and on hilly slopes. It can be identified by its thin stem, narrow leaves, and small white flowers. Well-established plants appear to have many stems originating from a common root crown. This milkweed grows from a taproot and doesn't like to be moved once established. Arizona milkweed is also called narrow-leaved milkweed and talayote.
Arizona milkweed attracts monarch butterflies and other pollinators. It is deer and rabbit resistant. Planting more milkweeds, even in small urban pockets, can provide personal satisfaction and education while helping to counter increasing threats to monarch butterfly populations.
Milkweed plants are the sole larval host plant for monarch butterflies as well as an adult nectar source for various pollinators. If you grow it, they will come!

Remember that MILKWEED CONTAINS TOXINS. The monarch caterpillar intentionally eats milkweed to become distasteful to protect itself from predators, hence the bright warning colors they feature as adults (butterflies). After handling milkweed, WASH HANDS THOROUGHLY and do not get the milky sap into your eyes or mouth. NEVER ingest any part of a milkweed plant.
