help Raspberry (Rubus idaeus) FAQ
Are Rubus idaeus raspberries native to North America?
Rubus idaeus is native to Europe and temperate Asia, although it is now cultivated far beyond that range. The closely related red raspberry native to much of North America is generally classified as Rubus idaeus subsp. strigosus.
Why is a raspberry called an aggregate fruit?
Each raspberry consists of many small drupelets clustered around a central receptacle. When a ripe Rubus idaeus fruit is picked, the receptacle remains on the plant, leaving the berry hollow inside.
Do raspberry plants produce fruit in their first year?
Traditional summer-bearing Rubus idaeus cultivars fruit on second-year canes called floricanes. Primocane or autumn-bearing cultivars can produce a crop near the tips of first-year canes, usually later in the growing season.
How should Rubus idaeus canes be pruned after harvest?
Spent floricanes should be cut to ground level after they finish fruiting because those canes will not bear again. Healthy new primocanes are retained to supply the following season's crop, unless the plant is an autumn-bearing type managed as a single annual crop.
