Asclepias californica * California Milkweed

California Milkweed grows in California's foothills and inland valleys in the lower 2/3 of the state. This photo was taken in May along the Kern River where Asclepias californica is quite plentiful. Seed was still young, mature seed would be more likely a little later in the season. The soil in that area is sandy well drained decomposed granite. There are a number of insect associations with milkweed that are quite interesting to observe as the milkweeds are quite toxic to most that might feed on it. Asclepias californica is a food and nectar source for the Monarch Butterfly and the Gray Hairstreak, and a great addition to the butterfly garden and the native wildflower garden.
