I may be able to get my hands on some Purple Fruited Edulis pollen (We have a Public Consevatry here) if I can, how long will it stay Viable for? Would like to see if I can get some fruit on my Edulis Flav
If the pollen is well dried and kept dry, it should last for weeks to even months if refrigerated. However, when crossing the purple and yellow forms, the yellow is always used as the pollen parent. If the two parents are the pure species, it may not work. However, if the purple form has some flavicarpa in its makeup, it possibly will work, so you should give it a go and see what happens.
