A striking tree for its interesting bark and massive framework. Widely adaptable to soil, trouble-free, and drought and pollution resistance. Easily transplanted. May be less hardy when young and rapidly growing. Fruits smell like turpentine when crushed (or stepped on). This tree is demonstrating invasive characteristics in suburban and urban fringe forests. It escapes intended […]
Well adapted to different light (even shade) and soil conditions, especially to dry situations. Relatively trouble-free, and one of the most fragrant of the mockoranges. None of the mockoranges have much landscape interest after the season of bloom. Becomes leggy if not pruned. Pruning should be done after flowering (flower buds form on previous years […]
Waxy gray berries were used by early settlers for making aromatic candles, and occasionally still are used for this purpose. Especially good plant for full sun and sandy soils, but grows well on many soils. Tolerates half shade. Relatively salt-tolerant. Forms colonies via suckers. Fixes nitrogen in the soil. Dioecious. Use female plants (when known) […]
Especially useful in wet soils. One of the most beautiful of trees, with habit comparable to Quercus palustris, but usually more irregular, and with a greater number of more slender main limbs. Silvery-gray, picturesque branching; strong horizontal accent. Difficult to transplant due to taproot; use container-grown plants when possible, or at least plants dug with […]
A good, trouble-free small shade tree worthy of greater use. Very graceful with many drooping branches that create a rounded habit. Best on drier slopes, and is usually found in native ecosystems. Slow growing, and difficult to transplant. Does not tolerate periodic flooding (as does Carpinus caroliniana) or salt. […]
This plant gets it common and scientific name from its sour-tasting leaves. The genus name is derived from the Greek word “oxys”, meaning sour, and “dendron”, meaning tree. Honey produced from the pollen of Sourwood flowers is considered valuable. The attractive, slightly fragrant flowers are often prolifically produced, especially in full sun, and are effective […]

'Jitsuge Tsu-nishiki' has large, intensely pink, double blossoms. These plants do best in a deep, fertile, and well-drained soil, with some protection from strong winds. In colder climates, some winter protection is beneficial […]

This cultivar is slightly susceptible to apple scab and powdery mildew and slightly to moderate susceptible to fireblight. Tends to […]
More tolerant of different sites than Taxodium distichum (Common Baldcypress). Prefers moist sites and can grow in water. Japanese beetles will feed on foliage. Does not like chalky soils with high pH. […]
The Russian Arborvitae is a low spreading, groundcover conifer that was discovered in Russia in 1921. It is generally easy to grow and can be a good substitute for Juniper in part shade situations, although it is best in full sun. This plant is not tolerant of extreme heat. Seeds of this plant can remain […]
