The following is for info. only:

(Plant Patent 16,309. Cultivar: KN-30-8.) Venus is the Dogwood we've all been waiting for. Not only are its blooms enormous and lovely, but it is superbly disease resistant, demonstrates fine winter hardiness, is drought tolerant, and has a low-branched, full habit that keeps it colorful right down to the ground. And as the fastest-growing Dogwood, it will grow up, fill out, and bloom spectacularly, all within a very few seasons.

These shamrock-shaped blooms are fully 6 inches wide and wonderfully symmetrical, with 4 huge petals surrounding a tiny green center. Float them in a bowl of water, or cut an entire branch and display in water for splendid spring color indoors. A fully-blooming tree is an unforgettable sight!

But the blooms are just part of Venus's beauty. The foliage always looks fresh and healthy, thanks to terrific resistance to Dogwood Anthracnose and Powdery Mildew. And the habit of this 20-foot-tall, 20- to 30-foot-wide tree is a bit out of the ordinary. Instead of sending up a bare trunk, it is branched low to the ground, and has a rounded, symmetrical outline.

Best of all, this Dogwood has superior winter hardiness so it can flourish farther north than many others, AND it is wonderfully drought-tolerant for the thirsty south and southwest. If you have had to pamper your Dogwoods to help them through climate crises, Venus will be your first truly low-maintenance specimen.

Bred by Dr. Elwin Orton, Jr., of Rutgers University, Venus is an interspecific hybrid. One part is C. kousa x nuttalli (the Pacific Dogwood), while the other is C. kousa. The result is an all-weather performer, far more gardenworthy than older varieties.

As an additional note, this selection is a hybrid between C. kousa and C. nuttallii.

A wonderful new Dogwood produced by Dr. Elwin Orton, Jr. of Rutgers University. Flowers are very large, 6 inches or more on established trees.

With some dogwood trees, the blooms come first and the leaves come later, but with this cultivar, the flowers and leaves arrive at the same time. It will grow in a variety of light conditions from full sun to shade. It reaches a height of 30'.

This tree is so new, it's pretty hard to come by. It's worth the hunt, though.


This plant has been said to grow in the following regions:

Winnetka, Illinois
