These are produced by grafting genetically different parents, different [[cultivar]]s or different species (which may belong to different genera). The tissues may be partially fused together following [[grafting]] to form a single growing organism that preserves both types of tissue in a single shoot.<ref>{{cite journal |author1=Norris, R. |author2=Smith, R.H. |author3=Vaughn, K.C. |name-list-style=amp| title=Plant chimeras used to establish de novo origin of shoots | journal=Science | year=1983 | pages=75–76 | volume=220 | doi=10.1126/science.220.4592.75 | issue=4592 | pmid=17736164|bibcode=1983Sci...220...75N |s2cid=38143321}}</ref> Just as the constituent species are likely to differ in a wide range of features, so the behavior of their [[Anticline#Anticline terminology|periclinal]] chimeras is like to be highly variable.<ref>{{cite book |last1=Tilney-Bassett |first1=Richard A.

Well-known examples of a graft-chimera are [[+Laburnocytisus 'Adamii'|''Laburnocytisus'' 'Adamii']], caused by a fusion of a ''[[Laburnum]]'' and a [[Broom (shrub)|broom]], and "Family" trees, where multiple varieties of apple or pear are grafted onto the same tree. Many fruit trees are cultivated by grafting the body of a sapling onto a [[rootstock]].<ref>{{Cite web|url=https://extension.unh.edu/resource/growing-fruit-grafting-fruit-trees-home-orchard-fact-sheet|title=Growing Fruit: Grafting Fruit Trees in the Home Orchard [fact sheet] {{!}} UNH Extension|website=extension.unh.edu|date=17 January 2018|language=en|access-date=2020-02-23}}</ref>
