Gardeners' Notes:

We were given a clipping as a gift. I kept it pot-bound for awhile before transferring to our yard. Not sure if it was the humid, sweltering heat that got to it, but it didn't survive. :(

I'm going to try again, but maybe with a seedling. Not sure if these are sold in the Michigan area or not.
