Ageratum seeds are very small and can hardly be seperated from the chaff. The seed is under the chaff, but to get viable seeds, you must wait until the pods are dried well. If you check them every day, you might be able to remove a lot (but not all) of the chaff. Just collect the seeds together with the chaff.
I do agree. They do go everywhere. I have some tiny ones in the crack of my concrete patio. My problem is that I can't identify many flowers from weeds when they are just coming up. Ageratums are unique and easy to identify but the others are difficult to ID.
I reaaly have tried collecting them, but May go out in a bit with a plain envelope and see wht goes on. Been getting a little rain and is finally clearing up, so I'll give it a try and let you know what happens. How about that? Got to start making labels for the seed swap too. Too early for some seeds but I am watching. Are you?
Well, I've been busy in the garden the last months. I grew a lot of new species. And now I'm busy gathering seeds.
About the Ageratum, just give them away with the chaff, I even sell them with the chaff, because I still didn't find out how to seperate them properly. Ageratum is just setting seed here, I'm going to try it again and if I'm lucky, I'll let you know.
Red -- If I grow it, I am compelled to collect the seeds. I have pretty ordinary flowers, but I am a good seed collector and saver. I just keep my seeds in those amber plastic perscription bottles, labeled, in a cookie tin, and in the fridge.
I haven't gotten any tiny ziplocs jet for swaping. But I don't think there will be much a request for the type of seeds I have. I gave hundreds of seed packages away in the spring locally just wrapped in computer paper.
It might be wetter here, especially in spring. Every spring it takes weeks before the ground is workable here after the snow melted. I never had a volunteer of Ageratum, although I grow them a lot. Sowing them indoors is always very succesful for me.
I know this is an old post, but I happened on it on 11/12 so I know others will also. There is a good picture of Ageratum seeds on GardenWeb. I don't know if I am allowed to put that link on this site, but you can get there easily, just google saving seeds of ageratum and the link will be in the list. You can even print the pic out. Hope it helps someone.
