Im pretty sure this has come from a New Zealand purple seed but other than the color not much else is the same.... I do grow other castors (red &pink) but this is by far the tallest I've ever grown. In this pic it is at least 15-20 ft and it has gotten taller since Ive take the picture. It has not made any flowers or seeds so I can't give any pics of that. Can anyone tell me what kind of castor I have here?
Im really hoping it will make a few seeds before the frost gets it! I would love to grow it again.
