I use FAA (for 1 liter: 900ml 70% Ethanol; 50ml Glacial Acetic Acid; 50
ml Formalin). I will either keep the flowers in the FAA or transfer to
70% ethanol after a few weeks. As the solution evaporates, I always top
off with 95% ethanol. The flower structure remains pretty well, but the
colors bleach quickly. If anyone knows better solutions that are safe,
I would appreciate hearing about them.
