It would be useful to include [North America] in the title.
True, I am new.
For what it’s worth, I wouldn’t collect Asclepias speciosa. The problem with it is that it’s an incredibly prolific spreader. If you introduce it to a landscape it will take over within a few years and be a detriment to the biodiversity. They also have a very narrow range of host species, so you’re providing for monarchs if they reproduce in your area but not the majority of your pollinators. Asclepias incarnata and Asclepias tuberosa on the other hand are miracle plants. The former helps to stabilise degraded river banks and ponds, the latter goes into general beds. Both are so fucking productive for pollinators that I try to incorporate them into any design I do. They should be going to seed by now wherever you are.
Beneficial natives spreading too prolifically is not on my current list of problems! Hopefully someone in their native range will adopt these seeds.
