Hopefully someone may have some of these seeds to trade. I have a variety of other species of Justicias or tell me what you would like. I have harvested over the last couple of days, Tecoma stans, Duranta erecta, Jatropha curcas, Nerium oleander, peach Canna indica, Dwarf red Canna indics plus some others. Presently forming seed is Megaskepasma erythrochlamys or Brazilian red cloak..
No help now but you tell me how to collect these seeds & I'll get them to you when they are available. I can get beautiful cuttings but I never see any seed. Must be one of those that you have to catch just right.
