First time I planted it, lasted for a bit, but then, dead...dunzo! Chalked it up to 'operator error.' Then read posts that everyone else struggled with it... so bought it again and experimented. Split it up into various spots with more protection... lasted longer, but then died again.
Third time, I decided to go rogue with almost complete shade. Consistancy of moisture (not too much, but constant moisture like the painted ferns prefer) also helps. Dont let the soil dry out.
Here's another pic where I planted a little piece in a shade bed (just to see if it would survive the winter). This is North side of house and the emerging bleading hearts grow 4-5ft tall, completely covering everything in this bed...ignored and left completely to the elements. It's just showing new growth.
Definitely try it again, and test this method. If anyone has a green thumb, its you!
