11. Armstrong Gardens

“I have purchased Asclepias Fascicularis, Asclepias Tuberosa, and Asclepias Curassavica at various Armstrong Gardens locations in the Los Angeles area. I have purchased Tropical milkweed that had instar 4 caterpillars munching on the milkweed – which gave me good assurance that no pesticides are used. You have to be careful though – if you get a milkweed that was not grown in California – like for instance Ascelepias Linaria that was grown in Arizona – out of state growers are required by regulations to treat everything even milkweed with pesticides before it can be sent to California. I had a detailed discussion with one of those growers. So it is best to stick with milkweed that came from local growers like “Monrovia” or other small local growers. Armstrong has readily given me the phone number of their milkweed growers so I could talk with them and see if they use pesticides.”
