I bought some Tortoise Berry seeds from Trade Winds a few years ago. I had a poor germination rate, less than 25%, and I then proceeded to kill the seedlings over the period of three or four months. I believe I was watering them too much, and/or they were in a potting soil that retained too much moisture. I have not seen anyone offering seeds besides Trade Winds, and they have not offered any, to my knowledge, in a few years.
