Barberry

A massive genus of 450 species of evergreen and deciduous shrubs native to a huge portion of the Northern Hemisphera as well as South America, tropical and northern Africa. The berries on most Barberries are edible, though often quite small.
Prefers sun to partial shade on just about any moist, well drained soil including clay. Most are drought and urban tolerant. Deer do not generally eat Barberry.
Most Barberries can be reproduced from half hardened cuttings taken in late summer and the deciduous ones can also be propagated from softwood cuttings taken in early summer. Seed sown in spring isn't very reliable because Barberries hybridize easily and resulting plants are variable. If grown from seed it is recommend to plant the entire seed during autumn.

Berberis canadensis ( American Barberry )
The North American native Barberry which is similar to Berberis vulgaris however is native to Maryland, Virginia and North Carolina ( very rare and isolated to a few mountain & Piedmont Counties ). Generally a moderate growing, low to medium size, clonal deciduous shrub, it can reach a maximum size of 6.6 x 6 feet. Unlike most other Barberries, this one may spread by rhizomes and usually forms clumps under 4 feet in height. The botanical name of this Barberry is misleading, it is not native to Canada. It has recently been found on the serpentine rock outcrop at Soldiers Delight Environmental Area near Reisterstown, Maryland. This is especially of interest because other sources consider it now extinct in Maryland and Indiana and it is ranked as of Special Concern in Tennessee. It is also extirpated in Pennsylvania ( previous local occurance in western part of state ), Alabama, Missouri, Illinois and Kentucky. It is rare in Georgia, the Carolinas, Tennessee, West Virginia and Virginia. It is now a threatened species however was once much more common before being systematically being eradicated due to it being a host for black stem rust which infects wheat.
This plant is very attractive and can be used as an erosion control or barrier plant in non agricultural areas.
The narrow, bristly-tip tooth, obovate leaves, up to 3 x 1.3 inches ( usually less than 2 inches in length ), are bluish-green, turning to deep orange during autumn.

The light yellow late spring flowers are later followed by elliptical red berries up to 0.4 inches across.
The berries are considered edible however I have not tried them yet.
The stems are armed with spines, up to 0.5 inches in length, that are often 3-parted.
It is unfortunately prone to Barberry Rust eliminating this shrubs chances of ornamental use in most of North America due to the fact the same rust can also infect wheat and ruin crops.
Hardy zone 5 to 8 in full sun to partial shade. It is drought tolerant.

'Stearnii'
Bright red spring foliage.

Berberis thunbergii ( Japanese Barberry )
A rounded deciduous shrub native to Japan. Some records include: 10 years - 6.5 x 6.5 feet; largest on record - 10 x 17 feet. Excellent for use in hedging. Though commonly planted in North America, in the east it does have invasive potential in many areas. It has naturalized to as far as the Upper Peninsula in Michigan and Wiarton, Ontario.
The smooth, oval leaves up to an inch in length are fresh green above and blue-green beneath. The foliage appears early in spring. In mild climates, the foliage may persist very late in autumn or even until early winter. During the mild December of 2011, many Japanese Barberries still had leaves just a week before Christmas.
The pale yellow flowers are borne in small racemes during mid spring.
They are followed by shiny red fruits, up to 0.4 inches, during late summer persisting through winter.
The stems are armed with short single spines.
It is often used for hedging.
Hardy zones 4 to 8; it will grow further north into zone 3 however as in Winnipeg, Manitoba is will be reduced to a foliage perennial. Berberis thunbergii even survives in much of Alberta. Resistant to Black Stem Rust and is ok to plant in agricultural areas where wheat is grown. Very easy to grow, they are virtually immune to pests and disease. Tolerates poor dry soil, compacted soil, clay, urban conditions as well as shade ( except forms with colored foliage will revert to green if lacking sun ). While drought tolerant, plants installed during the growing season will need generous water until they have a chance to develop a root system penetrating deep into the earth. Japanese Barberries are best planted during mid autumn to early spring; plants installed during late spring or summer will often drop their foliage if hot weather quickly follows. As for pruning you can do just about anything you want to a Japanese Barberry; they can be sheared but are usually allowed to grow their natural shape with a selective cut here or there to shape them. Old overgrown plants can be cut back to near groundlevel during early spring for renovation.
Many of the dwarf varieties collect litter, especially during fall. Often even a leaf blower won't work in removing this since the litter ( dried Oak leaves etc ) lodges on the thorns. I will typically prune off the lowest 4 inches of branches completely and remove any self layers thus making it easier to reach or rake under to give a neat appearance or get a good clean sweep with mulch.
Cultivars can be propagated from softwood or semi-ripe cuttings taken during summer.
