Stellar Nova™ Dogwood

A Modern Brilliance in Flowering Trees

The Stellar Nova™ Dogwood, botanically known as Cornus x 'Rutstar', represents a revolution in ornamental breeding. Developed by Dr. Thomas Molnar at Rutgers University, this vigorous hybrid combines the elegant spirit of the native flowering dogwood with the rugged resilience of the Kousa species. While many dogwoods struggle with the sweltering heat of midsummer, Stellar Nova™ is a "workhorse" in the landscape, maintaining dense, dark green foliage that resists curling and scorching even when temperatures soar.

Dramatic Late-Spring Bloom

As the early spring blossoms of other trees begin to fade, Stellar Nova™ takes center stage. In late May, it erupts in a canopy of extra-large, bright white floral bracts. These blooms are noted for their high reflectivity; Dr. Molnar describes them as being visible "from a thousand feet away" because they practically glow in the sun. Because it blooms slightly later than traditional varieties, it serves as the perfect partner to pink-flowering dogwoods like 'Scarlet Fire™', creating a synchronized and high-contrast seasonal display.

Four-Season Appeal and Versatility

Growing to a mature height of 10-15 feet with a tidy spread of 10-12 feet, this tree is perfectly sized for modern residential lots. Its upright habit makes it an ideal specimen for a front yard focal point, a courtyard accent, or a refined addition to a flowering border. When autumn arrives, the dark green leaves transition into a rich display of reddish-purple tones before falling to reveal a graceful, sculptural branching structure that provides winter interest. Best of all, this hybrid is sterile, meaning it focuses all its energy on its magnificent flowers and foliage rather than messy fruit production.
