I planted some this past year. It was the worst drought I have ever seen. However, it went in early and we had good rain up until June so it must have rooted itself pretty good. It all survived. This was in pretty good soil. If it was marginal soil, I think it probably would have died.If we stay in the drought what's the chances of the rhizomes living? Want to plant some as well but scared with the weather we have been in the past yrs?
