The Bring Back The Monarch Campaign Website and Xerces Society Website appear to advocate the purchase and planting of native milkweed seeds (and plug type transplants) that had been farmed by commercial nurseries located dozens to many hundreds of miles away:http://monarchwatch.org/bring-back-the- ... -suppliershttp://www.xerces.org/milkweed/
In other words, someone in Colorado can get on the phone and order speciosa milkweed seeds from a California nursery. Likewise someone in Los Angeles can order speciosa and fascicularis milkweed plug transplants from a northern California nursery.
But I've noticed our native California milkweeds vary alot in characteristics such as height, leaf, stem, flower and seed pod shape, texture and toughness, etc over short distances of as little as 50 miles. And since milkweed patches are stationary rather than migratory, this means they are locally adapted which also means they are almost certainly genetically distinct.
So these milkweed restoration projects will likely cause the mixing of genetically distinct strains or ecotypes of our western speciosa, fascicularis and eriocarpa milkweeds.
This made me wonder: Is this mixing of distinct milkweed populations a good thing? Why or why not? Or should we invoke the precautionary principle and promote the purchase and planting of only locally farmed milkweed seeds and plug transplants?
