The crown and the roots of the plant are perennial, but the canes that grow from the crown are biennial (they live for only two years). Most raspberries and blackberries grow fruit only on canes in their second (last) year of life. A few types produce a small crop of fall berries in their first year, but the big harvest comes in summer from the two-year-old canes.
Raspberries spread and produce canes from roots, too, but blackberries only grow canes from the crown.
While some raspberries and blackberries can grow into thickets without needing support, if you have limited space you should consider training the plants on to a trellis. Cane-berries need to be pruned annually to ensure good fruit production and minimize plant diseases.
We grow and propagate all the listed cultivars, but they rotate in availability year to year and the availability of some plants is limited. If you are unable to add an item to your cart it is likely that the quantity you ordered is not available.
