Re: Raja Puri hardiness?
Well it does depend like I said what state you live in. One state could be a warm zone 6 and the other gets cold ya know. living in zone 5 Ohio only hardy one I know of is Musa Basjoo. I never protected mine for the five years they were planted there. So there is a handful that will live in the 6-7 without portection or being dug up?
You could try the new stuff Dave Frankco has out.
Mulch them very well
Build a hoop house over them
Wrap bubble wrap around them and place chicken wire around them and add hay or leaves all around them.
Some people have used insulation to wrap them.
