It's a rare wild capsicum. It's been around the Finnish and German forums for many years and others such as John F grow it too. The berries have 1-3 seeds in them at best (contrary to what it looks like in the picture). They have no heat.
It has no culinary use IMO. The flowers have yellowish / green markings. It's very rare, but only if you're someone into these wild ones. This is a second year plant for me. I just enjoy saying I grew a rare one I guess.
Somehow they don't look hot anyway. They look great, but very much like some berry, but that's what chili "peppers" are, that just shows how wild this variety really is. Considering their size it's not surprising that they hardly contain any seeds.
