I recently had success growing, fruiting (and eating) fruit from a passiflora edulis 'Possum Purple' vine, and now want to try my hand at citrus. The space is an office windowsill with full southern exposure. A look at the Logee's site lists all sorts of citrus plants. Could anyone with a comment let me know which have been the most successful plants for this type of environment? I'm hoping to find varieties than can either be cut back when they get too big, or stay dwarf-ish to begin with.
