milkweed

Question

does milkweed spread other than by seeds. last year i got 2 seedlings from several i started. one died, the other matured but didn’t bloom. this spring about 2 inches from where the seedling that died was i have another plant growing, and where the one plant matured i now have several at various stages of growth. if it spreads by runners or whatever can it be divided, should it be divided and if so when?

Answer 1

Common milkweed spreads by rhizomes (underground runners or roots) which is why it can be such an aggressive spreader.
Milkweed has a long tap root and does not do well in trying to transplant or divide.
