LainausMy questions - Anyone want to confirm the lack of self-compatibility? Will I have to assist pollination and if so how do I do that?

Joe,

I grown several dozen C. pubescens varieties and only know of one variety that will not self and one other that I am not sure about.  PI 387838 from Equador requires a 2nd plant and a "white"-flowered variety from the Canary Islands (thanks PeterM) might need a 2nd plant.

There is little doubt in my mind that bees and other pollinators greatly improve pod set, but just shaking the plant seems to work.  I prefer brushing the blossoms together if at all possible.
