- Sterile is easy. Anyone with a pressure cooker can manage sterile. The
- hard part is WHAT germination media to use (what salts, how much sugar,
- what source of water, which agar or gelling agent....). The best I
- know of for Cypripedium species, Carson Whitlow, gets about 70% initial
- germination, and might get 1% big enough to survive the first winter
- after transplanting. Carson and I are still playing with his germination
- media, and it is amazing the difference between batches, when all you've
- switched is the (supposedly "inert") gelling medium. The media we're
- using are pretty different from the commercially available flasking media.

-
- Tropical genera that are popular with hobbyists (Cattleya, Laelia,
- Oncidium, etc.) are pretty amenable to flask germination. Of course
- part of the reason they ARE popular, is that they can be produced in
- large enough numbers easily enough to make the plants affordable.
- Even I can flask Cattleya, but I sure have no luck with Platanthera.
- Sigh.
