IMO Starfish is a very neat pepper, not because of its taste( the taste is not bad but nothing special, I would reccomend it as a powder),
but because of its ease to grow. Once I planted one in a pot of about 3 liters, and still gave a lot of fruit( seems to be an umbillicatum trait).
One guy I know has(or had ) a Starfish TREE, I guess it was about 2.5 meters high with a very nice stem and crown.
