Rubus fruticosus is often referred to as Blackberry, after the dark-coloured, edible fruits or Bramble, after the sharp thorns. It is a common and vigorous, deciduous shrub species from the family. Blackberry plants produce large thorns and have a scrambling habit. They are often regarded as a weed in many public areas due to their invasive nature. However they are great for wildlife, providing ample food and shelter to many species. Flowers are white to pale pink in colour, appearing from later spring to early summer. The fruits of Bramble plants are black in colour and sweet when ripe. Blackberry fruits are often used in jams and pies, but despite common knowledge, these fruits aren't true berries! Botanically, Blackberries are an aggregate fruit. Aggregate fruits are made up of smaller units, termed drupes, which contain single seeds. This is different from a berry, which is made up of distinct tissue layers, developing from specific parts of the flower. Usually, one ovary forms from one flower, resulting in the botanical definition of a berry. There are several very similar species and cultivars of this hardy plant that are designed to be less invasive as well as not bearing thorns and holding more fruits.
