Blackberry Bush - Rubus fruticosus is hardy in zones 3 through 9
Thanks to the sweet, edible berries the plant produces in mid-to-late summer, and the blackberry bush is a popular addition to gardens. The berries are used to make jams, pies, wines, and a variety of other dishes. The blackberry bush reaches heights of three to five feet and has a three to five-foot spread. Blackberry bushes grow well in Hardiness Zones 3 through 9.
Blackberry bushes prefer well-drained, slightly acidic soil amended with compost or other organic matter, but blackberry bushes are hardy plants that can withstand poor soil conditions. This bush produces abundant fruits with total sun exposure but withstands partially shaded areas well.
Blackberry Bush is drought-resistant
Blackberry is drought-resistant, and the bush is an attractive addition to butterfly gardens. Birds and bees are also attached to blackberry bushes, and the plant has delicate white flowers that provide ornamental value to mixed borders and privacy screens. When left undisturbed, blackberries form thickets, making the bushes suitable for ground cover—pruning the bushes after the last harvest in autumn controls growth and increases overall berry production.
The blackberry bush has thorns, erect reddish-green branches, and medium-green leaves with deeply serrated leaf margins. In spring, white or pink blossoms appear on the branches. The flowers have five petals. They are 1/2 inch in diameter. After the blossoms fall off, drupes appear. Blackberry drupes are initially green before turning red for a short time. The berry gradually becomes dark purple as it ripens.
Some blackberry plants produce drupes several times throughout spring and summer, allowing for successive harvests. Each berry has dozens of drupes, which form a berry similar to a raspberry in shape, size, and texture. The seeds are located inside the tiny drupes that make up each berry. In autumn, the blackberry bush loses its leaves and is dormant until the following spring.
