From:Portland, OR Region: Northwest Topic: General Botany Title: Looking for leaves of milkweed plants for experiment Answered by: Nan Hampton
I am an undergraduate chemistry student at the University of Portland and want to perform an experiment using milkweed leaves. How would I get milkweed leaves at this time of year? Any help you can provide is greatly appreciated.
Other possibilities are the greenhouses of public gardens such as Leach Botanical Garden and the Berry Botanic Garden in Portland, the Oregon Garden in Silverton or University of Washington Botanic Gardens in Seattle. Since you are doing a university research project, it might be possible that they would be able to furnish you with a few young plants if they are growing them in their greenhouses. There are other botanical gardens in or near Portland that you could locate by Googling "botanical gardens Oregon".
Finally, since both A. speciosa and A. syriaca are listed as caterpillar and nectar hosts for the monarch butterfly (Danaus plexippus) you might check with Monarch Watch and the Monarch Butterfly Website for sources of milkweed plants. Additionally, the Oregon Zoo in Portland has a butterfly exhibit, Winged Wonders, and might possibly have a supply, or know of a supplier, of milkweed.
