Joe,

I never grew this plant (it's not exactly common, is it?) but that's a nice one - how long have you had it?

And for all those curious, as I was, it's from the Pedilaceae family (sesame), so open your hearts to it - I daresay you'd have to open your wallets to get one half as nice as that.

Here is a link that might be useful: Looky Here - Sesame in Vancouver

That should be Pediliaceae.
