These are very high quality seeds professionally hand gathered from selected genetically superior trees in Bonny Doon, California, seed zone 097, at an altitude of roughly 1,000'. These seeds have been machine "upgraded" - that is to say the heavier seeds that are more likely to contain a viable embryo have been separated from the lighter non-viable ones. Redwood seeds generally have a very low germination rate, but you can expect a germination rate of close to 50% under ideal circumstances for these. Detailed germination instructions provided.
