'''''Fragaria''''' × '''''vescana''''' is a [[Hybrid (biology)|hybrid]] [[strawberry]] [[cultivar]] that was created in an effort to combine the best traits of the [[Gardengarden Strawberrystrawberry]] (''Fragaria'' x× ''ananassa''), which has large berries and vigorous plants, with the [[Strawberrywoodland strawberry]] (''Fragaria vesca''), which has an exquisite flavour, but small berries. [[Plants of the World Online]] considers it an [[unplaced]] taxon – "names that cannot be accepted, nor can they be put into synonymy."<ref>{{Cite web |title=Fragaria × vescana Rud.Bauer & A.Bauer {{!}} Plants of the World Online {{!}} Kew Science |url=http://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:939019-1 |access-date=2024-06-09 |website=Plants of the World Online |language=en}}</ref>

This cross cannot take place naturally. ''Fragaria'' x× ''ananassa'' has eight sets of [[chromosomes]] whereas ''Fragaria vesca'' has only two sets. Repeated attempts to cross these resulted in [[infertility|sterile]] offspring.

Researchers treated tissue from a ''Fragaria vesca'' plant with [[colchicine]] to create a [[mutant]] plant with four sets of chromosomes. This mutant was then crossed with a ''Fragaria'' x× ''ananassa'' plant, and vigorous fertile offspring were obtained. The offspring were found to be [[polyploidy|decaploid]], (having ten sets of chromosomes).

''Fragaria'' × ''vescana'' is not yet commercially important, but remains under development. While the plants are vigorous like their ''F.'' × ''ananassa'' parents, and the berries have the excellent flavour of the ''F. vesca'' parents, the berries are still quite small.

==''F.Fragaria'' x× ''vescana'' cultivars==

The following decaploid strawberries were released by the Swedish breeding program at Balsgård:

* ''' 'Annelie' ''' (1977)

* ''' 'Sara' ''' (1988) — 'Annelie' x× [('Sparkle' x× ''F. vesca'' 4x4×) open pollinated]

* ''' 'Rebecka' ''' (1998) — ('Fern' x× ''F. vesca'' 4x4×) x× ''F.'' x× ''ananassa'' F861502

German ''F.'' x× ''vescana'' cultivars:

'''Annelie''' (1977)

* ''' 'Spadeka' ''' (1990?1977)

* ''' 'Florika' ''' (19901989) — ('Sparkle' x× ''F. vesca'' semperflorens'Semperflorens' 4x) x× Klettererdebeere'Klettererdbeere H.Hummi'
