Late last summer, I collected some bloodroot seeds from some clumps that were growing on the grounds of a local zoo. I planted them in some small plastic containers and left them outdoors all winter, where they were sometimes covered with snow, and were subjected to several cycles of freezing and thawing. I live in Western Massachusetts, and bloodroot is a native wildflower here. Now the seeds are just starting to germinate. The seedlings are very delicate and tiny. Has anyone else on this forum ever grown bloodroot from seed ?

I've done this several times in the past. Once, many years ago, I was successful in growing a little bloodroot seedling that I planted in a shady garden at my workplace. I left that workplace the following year, and don't know if the seedling survived or not.

Over the past few years, I've attempted several times to grow bloodroot from seed. I've collected the seed, planted them in little containers, and left them outside for the winter. The seeds germinated the following Spring. But the seedlings are tiny and delicate, and have never lived past a week or so. I'm hoping for this current group of seedlings to survive and grow.

Watching your progress
good luck

Well, it's been a bit over a month since my original post, so here's an update.
About 20 or so little bloodroot seedlings germinated in early April in the small plastic container that I'd planted them in last Fall. I waited until late April to transplant them into individual little paper cups. I think perhaps I transplanted them too early in the past, which was why they didn't survive. Anyway, that was several weeks ago, and about a dozen of them are still alive and growing in the little paper cups. Some are in the shade and others are in the sun. So far, they're doing quite well. This is the longest that I've ever been able to keep them alive. In the past they didn't survive the transplanting. Right now, I'm hoping that the squirrels, chipmunks, or rabbits don't eat them ((they've already eaten a few of them). I hope that at least a few of them will survive until they can be planted out in the Fall.

for the up date

you might try a sprinkle if cayenne pepper on or near the small plants
It keeps critters off my tasty young plants.
