Little Yellow Flowers on my Purple Wave Petunias
I cannot find anything on the web about this. I have to assume that the seeds are something I can replant. Curious as to why my purple petunias are putting out little yellow flowers with the pods, the pods are splitting open and tiny black seeds are all over. I thought that after the regular flowers dried up there was supposed to be seeds but they just dry up and I pull them off and throw them away and more nice puple flowers just keep coming. It's mid summer here now and they are doing quite well.
Can I remove these flowers and pods and keep the seeds till next spring and replant after I get them started?
I thought I would just shake the seeds out of the pods and put them in a small glassine envelope and keep them in a plastic pill container. Any comments about this?
Should I just sow them early after the last frost?
