Editing Amelanchier (section)

===Garden hybrids===
Since classifications have varied greatly over the past century, species names are often used interchangeably in the nursery trade. Several natural or horticultural [[Hybrid (biology)|hybrid]]s also exist, and  many ''A. arborea'' and ''A. canadensis'' plants that are offered for sale are actually hybrids, or entirely different species. [[Amelanchier × grandiflora|''A''. × ''grandiflora'']] is another hybrid of garden origin, between ''A. arborea'' and ''A. laevis''. The cultivar 'La Paloma' has gained the [[Royal Horticultural Society]]'s [[Award of Garden Merit]].<ref name = RHSPF>{{cite web | url= https://www.rhs.org.uk/Plants/167959/i-Amelanchier-i-La-Paloma/Details

A taxon called ''[[Amelanchier lamarckii]]'' (or ''A.'' x ''lamarckii'') is very widely cultivated and [[naturalisation (biology)|naturalized]] in Europe, where it was introduced in the 17th century.  It is [[apomixis|apomictic]], breeding true from seed, and probably of hybrid origin, perhaps descending from a cross between ''A. laevis'' and either ''A. arborea'' or ''A. canadensis''.  While ''A. lamarckii'' is known to be of North American origin, probably from eastern Canada, it is not known to occur naturally in the wild in North America.<ref name=bean1>Bean, W. J. (1976).
