I know nothing about the zoning survival for these. I did grow seedlings of the 3 main shades over the last 2 years. Planted out the seedlings into the garden (zone 10) when they were about 6 months old. These went dormant this summer and are now coming away well. Why I mention that is that as yours have not gone dormant at all, would they need hardening off slowly before introducing them into the garden? Ina Crossley.
