Blackberry bushes prefer well-drained, slightly acidic soil that is amended with compost or other organic matter, but blackberry bushes are hardy plants that can withstand a poor soil conditions. This bush produces abundant fruits with full sun exposure, but withstands partially shaded areas well.
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 thorny, erect branches that are reddish-green and medium-green leaves with deeply serrated leaf margins. In spring, white or pink blossoms appear on the branches. The flowers have five petals and are about 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 over the course of spring and summer, allowing for successive harvests. Each berry has dozens of drupes, which forms a berry that is 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 it leaves and is dormant until the following spring.
