USA Official State Tree of Missouri

Flowering Dogwood

(Cornaceae Cornus florida)
Adopted on June 20, 1955.

 

On June 20, 1955, the flowering dogwood, Cornaceae Cornus florida,  became Missouri's official tree. The tree is small in size, rarely growing over 40 feet in height or 18 inches in diameter. The dogwood sprouts tiny greenish-yellow flowers in clusters, with each flower surrounded by four white petals. The paried, oval leaves are olive green above and covered with silvery hairs underneath. In the fall, the upper part of the leaves turns scarlet or orange and bright red fruits grow on the tree.

 

White flowers bloom in spring. Dark green foliage changes to red in fall. Red berries remain on tree late in fall.

 

Flowering dogwood (Cornus florida) is one of America's most popular ornamental trees. Known to most people simply as dogwood, it has other common names, including boxwood and cornel. The species name florida is Latin for flowering, but the showy petal-like bracts are not in fact flowers. The bright red fruit of this fast-growing short-lived tree are poisonous to humans but provide a great variety of wildlife with food. The wood is smooth, hard and close-textured and now used for specialty products.

 

State arboreal emblem.
10.040. The flowering dogwood scientifically designated as Cornus Florida L. is declared to be the arboreal emblem of Missouri and the state department of agriculture shall recognize it as the official state tree and encourage its cultivation on account of the beauty of its flower and foliage.
