They require summer tipping, unlike red raspberries, because individual canes will grow to unmanageable lengths. Black raspberries bear their fruit in late June through July, and are the most winter tender of the raspberries. Purple raspberries initiate new canes predominantly from the crown, but may sucker between plants as well. They are grown essentially as black raspberries are, and have intermediate cold hardiness. Gold raspberries also are available, although they are not widely grown.
Eastern blackberries can be thorny and erect, or thornless and trailing.
Because of their trailing growth habit, they require trellising. Thorny types often have excellent fruit quality, but the thorns are brutal. They do not require trellising. Tayberries were bred by crossing a blackberry with a raspberry. The flavor of the fruit reflects this parentage, and many people feel that a ripe tayberry is the most flavorful bramble of all.
