Redbud is the name for a group of trees and shrubs native to Asia, North America, and southern Europe. Redbuds are particularly beautiful early in spring when they are covered with delicate blossoms, each about 1 inch (2.5 centimeters) long. The flowers, which may be pink, purplish-pink, or white, reach full bloom before the leaves appear. Redbud trees have smooth, reddish-brown bark and heart-shaped leaves. The trees bear many seeds in flat, thin pods. The seeds are a valuable source of food for animals.
