Strumaria forms green seeds very quickly after flowering, much like Acis autumnalis. and the Strumaria seeds fall when green. Acis seeds ares released when they are brown-black and ready to plant. photos of Strumaria in fruit now Oct 19, 2014. https://flickr.com/photos/32952654@N06/… do Strumaria seeds need a period of further maturation on the soil surface under cool or warm conditions before sowing or can they be sown immediately and watered in?
