The basil will turn brown and it is very much like collecting coleus except the seeds are bigger. It can be time consuming but for that one, I now just cut the dry stalk in a paper bag, then run my fingers along the stalk to release the calyxes (?) and store it that way. Later, I might put it in a plastic ziploc once it is fully dry. You can spend forever cleaning the seed and chances are you will never use it all. Same with coleus. Coleus you have to sit there and keep rolling the chaf between your fingers over a white plate. The seeds will drop out. Very slow. Can take days. I wonder how people with sieves do it.
Amaryllis, I did many years ago. Pretty easy and obvious is all I remember. I think that was pretty straight forward.
There is no one rule for all plants. Sometimes it is a matter of getting to know the plant and sometimes you can't get past checking the plant everyday, waiting for the right time before the plant disperses it in its way.

Ok, getting better, got basil, amaryllis and kiss me kate!

How do you collect amaryllis seed? How do you keep them?

Dottee,

After they're successfully fertilized (either by hand with a paintbrush which I do about 5 times a day as long as there is a stamen and a pistol, or via nature!), you will notice that a bulge forms at the base of the flower. So if you have 4 flowers, you probably will get 4 buldges, or seed pods. I just leave them alone and let the flower drop off in it's own good time and evenutally you will have nothing but a stalk with the seed pod on top. After about 3 or 4 weeks of looking at the pod, you will notice that it turns brown and springs open reavealing the seeds. I just spread them out on a plate to dry for a day or two and then put them in baggies.

Is this the same method for collecting HOSTA seeds?
I was told something about acid free paper and stopped trying. Is Brown paper acid-free or did I misunderstand something?
