Butterfly weed questions: transplanting, propagating in water
Butterfly weed (Asclepias tuberosa) doesn't transplant because it has a long taproot that it doesn't like having disturbed: is this true?
Some butterfly weed grows in a nearby small field and I'd like to add some to a wildflower area in my backyard.
If it's true that butterfly weed doesn't transplant well, what does this mean? 50% fatality rate? Forget it, don't bother? It can be done if you dig deep down and get a good length of taproot?
I also read that butterfly weed can be propagated in water.
If this is true, what do I need to do? Cut a stem off near the ground, strip the lower third of its leaves and then stick it in some water until I see roots start to grow out the bottom, then plant it?
If this will work, does it matter if the stem is already flowering at the top or is going to flower soon? (My thinking is would that take up too much of the plant's energy and make it hard to grow new roots at the bottom?)
Thanks in advance for any suggestions or insights.
