By the way the plant name Streptocarpus means "twisted fruit." If fertilization is successful the seed pod(fruit) grows long and slender- generally right before seeds are fully ripe, the pod will twist. You have to keep an eye on it because the twist will start to split open. That's when you need to wrap the pod in tissue or even end wrap from a beauty items shop and set it in a safe place (not near fans or drafts) so you can safely harvest the seeds .
