Apples and peaches and other common fruit trees have complete bisexual flowers. But kiwi is not the same, they are functional dioecious plants - male plants only stamens, can only produce pollen; and functional female plants, although both pistil and stamens, but these stamens are only furnishings Only, can not produce qualified pollen, these appearance of the bisexual flowers are only female flowers only. Therefore, all kiwi must be male and female plants with each other in order to truly achieve the results of flowering.
