In older days, blackberry bushes were called bramble bushes.Flowers appear on the blackberry bush in late spring. The blackberry is unusual in that flowers and fruit may appear on the bush at the same time.
Blackberries spread rapidly. This is done with the assistance of birds and animals.
Blackberries contain tannic acid. This has been used over the years as an astringent tonicfor diarrhoea, dysentery, etc.
