We don’t normally think of hollies as being flowering tress but of course they are, as members of angiosperms (a.k.a. the magnoliophyta) they are flowering plants. Their flowers are not nearly as showy as their fruit, however, consisting of tiny, yellow flowers. Holly flowers are generally greenish white and as you can see in this picture, on this particular holly they are grouped along the stem in. They have four petals and this holly, like most species of Ilex is dioecious, meaning that there are separate male and female plants. This one is apparently male, as it has flowers each year but never has fruit.
