Cornus x rutgersensis hybrids

This exciting new hybrid series has been developed at Rutgers University in the U.S.A. as a result of crossing 
C. florida and C. kousa by Dr. Elwin Orton.

The trees have a vigorous habit to about 6m in 20 years and are all very floriferous. They all have a central leader and tend to branch almost from the ground.

They are resistant to anthracnose and flowers last for several weeks. Bright red autumn colour is an added bonus!

They have performed superbly well here and seem to truly combine the best of both their parents.

Cornus rutgersensis Aurora CORNUS 'Aurora'
Uniformly white flowers from top to bottom, often so densely flowered that the foliage is invisible! The flower bracts are large, and overlapping with rounded edges.

CORNUS 'Celestial'
Originally named 'Galaxy', it is of erect habit but with nicely spreading limbs. The rather cupped flowers have a green tinge to them when they first open, then flattening out and turning to a brilliant white.

CORNUS 'Constellation' 
As hinted at in the name, this one gives a more star like, airy effect as the bracts are distinctly separated. Upright in habit, becoming taller than it is wide, it is well suited to a smaller site where a solid tree would be overpowering.

Cornus rutgersensis Ruth Ellen CORNUS 'Ruth Ellen' 
This is the first of the Rutgersensis to bloom and the lovely flowers last for ages. The white bracts mature to pink and look rather like handkerchiefs hung out to dry.

CORNUS 'Stardust' 
This selection has more resemblance to its florida parent than the others in the group. Thus it can become heavily branched from low down, becoming wider than tall. The white bracts do not overlap as they develop, though they do mature to pink.

CORNUS 'Stellar Pink' 
The beautiful creamy bracts are flushed with pink from the tips on this selection make it most attractive. Very profuse flowering every year. Strong, upright habit makes this a brilliant introduction.

CORNUS 'KN30-8' (Venus)TM
This is the first release of the next generation of hybrids from the Rutgers University. In contrast to those above, it is a product of C. kousa x C. nuttallii, supposedly resulting in the largest flowers of all the dogwoods at up to 15cm across. That will be something to see for sure, though I should temper my enthusiasm by reminding you that a display of that magnitude will be dependant on appropriate growing conditions and weather.
