Nursery contributed plant descriptions

Of all the species of Eucalyptus, E. erythrocorys has one of the most unusual bud-caps. Like other species it lacks petals, relying instead on the tuft of colored stamens for floral showiness. The stamens are initially concealed under a bud-cap, which is pushed off by the developing stamens as they mature. E. erythrocorys is known as the red-cap gum because the bud-caps are scarlet in color. They also have a wonderful rough texture and ridges that form a cross. The red color of the caps contrasts nicely with the yellow burst of stamens that emerges when they are shed. The tree is of modest proportions, reaching a height of about 20-25 feet. It has sickle-shaped green leaves, a white trunk, and branches which are reddish at the tips. It is not widespread in nature, occurring only in a small area of Western Australia a little north of Perth.
One of the most beautiful Eucalyptus in my opinion. The flowers have interesting red buds which pop open to reveal luscious yellow-green stamens that arrange themselves into four clusters. The flowers are large (2-3”) & bloom for a long time (Fall-Spring) & look fantastic in a vase. This tree is native to Australia where it can be found growing in sandy soil & receives rainfall equivalent to that of Los Angeles. So it is fairly drought tolerant & does best with well-draining soil. Growing 25-30' tall & wide & generally multi-trunked, this tree is also fast growing. The curving blue-green leaves are another attribute to an already stunning plant. Would make a showy addition to any garden. Loved by hummingbirds!
