Black Satin Blackberry is a very productive, vigorous plant with large, firm, berries which have a sweet, delicious flavor. It will require some support for its limber, self trailing vines. It is a midseason producer, with crops ready in July in most areas. These berries are a favorite for jams, jellies, pies and just eating fresh. They keep well. This is a self pollinating, but are more productive when planted with another variety. Hardy to 15 degrees below 0 (and if you ever get that here in Phoenix your blackberries will be the last thing you are thinking about).
