Cornus kousa Scarlet Fire (Kousa Dogwood)
Scarlet Fire Dogwood, Cornus kousa 'Rutpink'
Prized for its unique rich fuchsia flowers, Cornus kousa Scarlet Fire (Kousa Dogwood) is a small deciduous tree with 4 seasons of interest. In spring, a profusion of deep pink to fuchsia, star-shaped flowers, 4-5 in. across (10-12 cm), cover the tree, creating a striking floral show. Lasting 6-8 weeks, their non-overlapping and pointed bracts give them a very distinct shape that along with their striking color sets this dogwood apart from other Kousa dogwoods. The blossoms give way to large pinkish-red, strawberry like fruit in summer, which persist into fall, unless devoured by hungry birds. In summer, its canopy of layered branches, clad with ovate, dark green leaves, with purple tinges in new growth, provides shade and beauty. In the fall, it offers spectacular bright color when its foliage turns attractive shades of red and orange. In winter, its exfoliating, mottled, tan and gray bark adds interest to the landscape. Noted for its disease and pest resistance, cold and heat tolerance, plant this flowering tree is as a specimen or in small groupings for a dramatic effect. This Kousa Dogwood cultivar was developed in 2016 at Rutgers University.
