Raspberries belong to the genus Rubus, which is a part of the Rose family. Cultivated raspberries have been derived mainly from two species, the wild red raspberry (Rubus ideaus) and black raspberry (Rubus occidentalis). Purple type is a cross between the black and red raspberry, and yellow type is a mutant red raspberry.
Raspberries' underground root stem and crown are perennial, and canes from underground buds are biennial primocanes (first year canes) and floricanes (canes in second year).
There are over 200 species of raspberries.
Raspberries can be grown from the Arctic to the equator.
Receptacle remains on plant when fruit is harvested leaving a hole at the bottom of the fruit.
Fruits are red, yellow, orange, purple or black.
60-70 pints of fruits can be harvested from 100 feet row.
Raspberries can be harvested from early summer through fall.
Raspberries are sold in pound units.
Average yield per acre in Illinois varies. For example, black raspberries yield 2,000 pounds/acre and red raspberries yield 4,000 pounds/acre.
