I dug these up this past weekend. I think the plants were 7-8 feet tall when an early frost got them.

They look pretty dead! Was this supposed to be their second year?

BBeth,

This species is perennial (roots can lie dormant through winter) but not at all hardy here in Z6A. I did not bother trying to dig them up back in the fall because I knew I'd just have to find something to fill the holes. Last weekend, I filled the holes with garden soil and 5 new seedlings.

I have overwintered this species in the basement before and they do come back. But these are so easy to grow from seed, I did not bother this year.

I am also growing this species and am still learning about it. I have heard from some people that it is a perennial but others say it is a biennial. I kept mine in the greenhouse this winter but let them stay cool without freezing. All the leaves dropped off, but now they are coming back to life.

Hi Kevin, I have seeds for this type and was wondering was that root system & those big stumps produced in just one growing season???
Also, what size pot did you need for overwintering?

Tks,
Erynne

BBeth,

Yes, that is what happened for me back when I overwintered them in the basement. Everything above the surface was already dying in the cold (but not quite freezing) weather. But the roots seemed fine. So I dug them up and potted them and put them in the basement. I put them back in the ground in the spring and they came right back.

I should clarify by saying that I have a full basement and it is climate controlled! It is certainly stays cooler than the rest of the house and I would estimate that it only gets down to 50F in the winter.

Erynne,

There are 5 stumps there in the photo. 4 of them are from just one season. The 5th was overwintered in a pot in the basement the previous winter.

I used a 12-inch diameter pot. But since the roots don't seem to grow during the overwintering, I think you'd just need to make sure that the pot bigger than the roots.

I also used a potting soil. But since the roots did not appear to be growing, I am not sure it was necessary.
