I purchased two of these along with one of the bright green leaves from the little cutie series. The dark ones grew very quickly and have flowered multiple times. I planted them in morning Sun with some late afternoon shade. The green one isn’t growing as quick. Although, it too has bloomed numerous times. The green one is smaller per the specifications. The two dark leaved ones seem to be growing larger then 8 inches in width. I haven’t measured but by just looking, I know they are slightly wider. I would say about one foot.
