Need more than one plant for proper pollination?
Hi milkweed fans,
I have a tiny backyard, and would like to try just one of each kind of milkweed, if I can make room for them all.
However, From http://www.fs.fed.us/database/feis/plants/forb/ascspe/all.html
"Most Asclepias spp. are self-incompatible, requiring crosses between genetically different individuals to produce viable seeds...."
This sounds like I need more than one plant, for each type of milkweed. Or, can A. tuberosa help to pollinate A. incarnata, for example?
If I do need at least two of each type, for future propagation potential, does each plant have to come from a variety of pods/parents, and not a single milkweed pod source, to avoid genetically identical siblings and sterile seeds the next generation?
