The Chinese Catalpa is smaller than other Catalpa species, generally only reaching 30 feet. It produces attractive yellow-white flowers in the spring, but they are not as ornamental as those of other Catalpa species. Its coarse winter trunk and branches are bold and striking; picturesque, but can be too coarse for many urban landscapes. Best […]

Franklinia is a small tree or large shrub that was originally discovered in 1773 by John Bartman (Royal Botanist for North America appointed by King George III) and his son, William. Together, they found a small group of the species growing along the Altamaha River in Georgia, and since then no other wild populations have […]
‘Shasta’ is a prolific bloomer and handsome plant that has strong, horizontal branching. The Doublefire Viburnum is fertile and more commonly used in the landscape than the sterile Japanese Snowball Viburnum (Viburnum plicatum f. plicatum). The white flowers are reminiscent of a lace doily with sterile showy flowers at edge surrounding the non-showy fertile flowers. […]
‘Purpureus’ is known for its purple-pink fruiting panicles. Can be pruned to low framework each year to promote plant coloration which occurs best on vigorous stems. Misty fruiting panicles give the species its name. The fine-textured hairs on the fruit pedicels and peduncles change colors, being best when tinted smoky purple to pink. […]
A striking specimen tree flowering later than the Flowering Dogwood (Cornus florida) and differing in having pointed bracts. The variety chinesis has larger flower bracts (up to 2.5″ long) than the straight species. Better adapted in cultivation than C. florida in much of the Midwest. For best flowering, place in full sun. Quite resistant to […]
A reliable bloomer that is common in commerce. Flower color does not always combine well with some other flower colors. Flower color bleaches out in high pH. Can be subject to winter burning of foliage in exposed sites near the limits of its range, but this cultivar can tolerate extreme heat and extreme cold (to […]
‘Spectabilis’ is a well-known and high quality Forsythia variant that has been around for many years. It is a very vigorous grower and prolific bloomer with bright yellow flowers that smother the branches early in the spring. ‘Spectabilis’ flower buds have better cold hardiness than many cultivars, but flower buds can be killed by severe […]
‘Flaviramea’ has yellow twigs that are especially prominent in winter. High susceptibility to canker. Grows well in a variety of situations, including wet soil. Easy to transplant. Relatively trouble-free. A three-year pruning cycle improves form, vigor, and winter stem color effect. Cutting all stems 6-12" from ground in late winter has similar effect. Best in […]
