Although kinnikinic is native in my area, these are cultivars from the garden centre that seem to contain genetic material from more than 200 miles away.
I heard this about wild collecting kinnikinic and manzanita. I used to work in a nursery where we collected wild seed and germinated it. These went through several repottings before being sold and seemed fine. I'm hoping that because this is a nursery plant it is more tolerant.
