Raspberries are an important commercial fruit crop, widely grown in all temperate regions of the world. Many of the most important modern commercial red raspberry [[cultivar]]s derive from [[Hybrid (biology)|hybrids]] between ''[[Rubus idaeus|R.&nbsp;idaeus]]'' and ''[[Rubus strigosus|R.&nbsp;strigosus]]''.<ref name=rhs>Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan {{ISBN|0-333-47494-5}}.</ref> Some botanists consider the Eurasian and American red raspberries to belong to a single, circumboreal species, ''Rubus idaeus'', with the European plants then classified as either ''R.&nbsp;idaeus'' [[subspecies|subsp.]] ''idaeus'' or ''R.&nbsp;idaeus'' [[Variety (botany)|var.]] ''idaeus'', and the native North American red raspberries classified as either ''R.&nbsp;idaeus'' subsp. ''strigosus'', or ''R.&nbsp;idaeus'' [[Variety (botany)|var.]] ''strigosus''. Recent breeding has resulted in [[cultivar]]s that are thornless and more strongly upright, not needing staking.{{cn|date=October 2023}}

The black raspberry, ''[[Rubus occidentalis]]'', is also cultivated, providing both fresh and frozen fruit, as well as jams, preserves, and other products, all with that species' distinctive flavor.

Purple raspberries have been produced by horticultural hybridization of red and black raspberries, and have also been found in the wild in a few places (for example, in [[Vermont]]) where the American red and the black raspberries both grow naturally. Commercial production of purple-fruited raspberries is rare.                   

''Blue raspberry'' is a local name used in [[Prince Edward County, Ontario]], Canada,<ref>{{cite book |last=Woolfrey |first=Sandra Marshall |url=http://www.sandrawoolfrey.ca/wp-content/uploads/2010/07/countydisc241.pdf |title=A Country Mouse with one paw in the Village:Growing up in Prince Edward County |access-date=23 October 2021 |archive-date=21 September 2013 |archive-url=https://web.archive.org/web/20130921055635/http://www.sandrawoolfrey.ca/wp-content/uploads/2010/07/countydisc241.pdf |url-status=live }}</ref> for the cultivar 'Columbian', a hybrid (purple raspberry) of ''R.&nbsp;strigosus'' and ''R.&nbsp;occidentalis''.<ref>{{cite book |last1=Hedrick |first1=U.P. |url=https://www.biodiversitylibrary.org/item/30382#page/10/mode/1up |title=The small fruits of New York |last2=Howe |first2=G.H. |last3=Taylor |first3=O.M. |last4=Berger |first4=A. |last5=Slate |first5=G.L. |last6=Einset |first6=O. |publisher=J.

Both the red and the black raspberry species have albino-like pale-yellow natural or horticultural variants, resulting from presence of recessive [[gene]]s that impede production of [[anthocyanin]] pigments.<ref>{{cite journal |journal=Frontiers in Plant Science |volume=7 |last1=Rafique |first1=Muhammad Z. |last2=Carvalho |first2=Elisabete |last3=Stracke |first3=Ralf |last4=Palmieri |first4=Luisa |last5=Herrera |first5=Lorena |last6=Feller |first6=Antje |last7=Malnoy |first7=Mickael |last8=Martens |first8=Stefan |title=Nonsense Mutation Inside Anthocyanidin Synthase Gene Controls Pigmentation in Yellow Raspberry (''Rubus idaeus'' L.) |date=19 December 2016 |doi=10.3389/fpls.2016.01892 |doi-access=free |pmid=28066458 |hdl=10449/36981 |hdl-access=free }}</ref> Fruits from such plants are called golden raspberries or yellow raspberries; despite their similar appearance, they retain the distinctive flavor of their respective species (red or black). Most pale-fruited raspberries commercially sold in the eastern United States are derivatives of red raspberries. Yellow-fruited variants of the black raspberry are sometimes grown in home gardens.

Red raspberries have also been crossed with various species in other subgenera of the genus ''Rubus'', resulting in a number of [[Hybrid (biology)|hybrid]]s, the first of which was the [[loganberry]]. Later notable hybrids include the [[olallieberry]], [[boysenberry]], [[marionberry]], and [[tayberry]]; all are multi-generational hybrids. Hybridization between the familiar cultivated red raspberries and a few Asiatic species of ''Rubus'' has also been achieved.
