Hamamelis virginiana, American witch hazel, is a native shrub or small tree that blooms in the autumn with wild looking yellow flowers.

Flowers

American witch hazel, Hamamelis virginiana, flowers grow in tight clusters of 1 to 4 at leaf axils.

The flower has 4 petals which are narrow crinkled ribbon-like, less than an inch long, and extend outward in a non-orderly manner.

Cluster of flowers: It is difficult to get a photo of a single flower with only its 4 petals.

The wild array of of bright yellow petals is a welcome when most flowers in the woods are gone.

Flower buds continue to open in October through November.

In the photo to the left, are flower buds with yellow petals peeking out of the sepals and bud scales. The bud scales are the outer shorter, darker tan covering on the bud. Next, the longer light tan coverings are the sepals.

The cluster stalk which is about 1/4 inches long emerges from the edge of a leaf scar. The flowers are sessile (stalkless) on the cluster stalk

Flower closeup: The flower has 4 petals. The flower pistil has 2 carpels, each with one ovary, one style, and one stigma. Two stigmas are easily visible. There are 4 fertile stamens and 4 nectar bearing staminodes. Also the flower has 4 sepals that are recurved (curved backwards). The stamens are immature here.

The pollen sacs have exited the mature anthers and some are releasing pollen

This microscope photo shows a staminode just in front of a petal. The staminodes contain nectar glands which attract insects for pollination.

Fruit

American witch hazel has a very unusual reproduction process. Flowering and pollination occurs in the fall and then development stops and the flower overwinters dormant. Development restarts in May arround the time when the leaves start and arround that time fertilization also occurs. This delay can be as long as 7 months. After fertilization, the fruit develops reaching maturity in late August and remains on the plant even while the plant is blooming.

The calyx, sepal cup, is about 3/16 inches across. After pollination in the fall/winter the petals and stamens wither but the calyx continues through winter.

Flowers are pollinated in the fall. However, fertilization, fruit and seed development occurs the following year in the spring. June photo of developing fruit in the summer.

Leaves and Plant


The leaves are simple, alternate, oval shaped about 3-6 inches long with wavy edges. The base of the leaves vary from heart shaped to rounded and is asymmetrical. The leaves turn yellow in the fall. Leaf buds do not have scales.

Asymmetric leaf base: Note that in this leaf the left side extends past the right side.

Stellate hairs. The external surfaces of the flower scales and sepals are densely covered with stellate hairs and the leaves have some also. It is easier to see that the hairs are stellar on the leaves. The microscope photo shows a stellate hair

The shrub/small tree grows to be about 15-30 ft. tall is multistemed and has spreading branches.
