Only about 1/4 of my seeds germinated (and I did have them under a humidity dome). Not sure if was the seed or my technique, although I didn't have great success last year, either. I managed to get 4 plants started, so that will have to be satisfactory for this year.
A friend of mine has kept on going through the winter by rooting a cutting (!) Who knew? May try that at the end of this season.
