I haven't yet heard some really good reasons why seeds of rare and endangered species should not be grown by hobbyists. ====================================================================== The seed exchanges I was thinking of when I said that seeds of endangered plants shouldn't be offered on them are the ones that have over 5000 seed offerings each year. The seeds go out in order of the request being received, donors first. There is no guarantee that the people receiving the seeds will be able to grow them. NARGS (North American Rock Garden Society) will not list seed of endangered plants. I don't know what happens if such seed is donated. Perhaps it is given to a botanic garden, which is what happens when CITES listed plants are discovered by Customs inspectors. ACGBC (Alpine Garden Club of British Columbia) makes a point of not publishing names of seeds if they don't have enough to meet expected demand. If they receive a donation of only a few seeds, they will give them to someone who has already demonstrated success with similar seeds. This policy is in place for all seeds, not just endangered ones. The seedlists of specialized societies is the place for seeds of rare plants. If I had a rare plant, I would first distribute it locally, since it had already shown it could be grown successfully in my area. (This would also give me a good chance of getting some back if mine died.) Later I would send seed of it to a specialist list. Only after it was well-established would I send seeds to a large general list. -- Diane Whitehead Victoria, British Columbia, Canada maritime zone 8 cool mediterranean climate (dry summer, rainy winter - 68 cm annually) sandy soil
