A Little Slow to Start, but Now Prolific

4 out of 5 stars Jul 14, 2021
Sowed 4 rows of these, and they took quite a while to germinate. About a month, if memory serves. About half of them didn't germinate, but then the ones that did, now that they've survived, have spread and continue to spread very prolifically, which is fine and good. Intending to let them go to seed and self grow to fill out the space they've been allotted. Growing well now.
