I also am interested in provenance, and always try to keep track of seed donors and the places wild seeds came from. Some seed exchanges that used to publish detailed information (altitude, soil, name of mountain, etc) have stopped doing so. I think this is because of the danger of endangered plants' locations becoming known. I disagree with the policy. Seed of endangered plants should not be offered on seed exchanges, and many plants are in no danger of being over-collected, so publishing their locale will not be a problem. -- Diane Whitehead Victoria, British Columbia, Canada maritime zone 8 cool mediterranean climate (dry summer, rainy winter - 68 cm annually) sandy soil
