'''''Acer triflorum''''', the ('''Threethree-flowered Maplemaple'''), is a species of [[maple]] native to hills of northeastern [[China]] ([[Heilongjiang]], [[Jilin]], [[Liaoning]]) and [[Korea]].
 
It is a [[deciduous]] [[tree]] that reaches a height of about {{convert|25|m}} but is usually smaller.<ref name=xu>Xu, T.-z., Chen, Y., de Jong, P. C., & Oterdoom, H. J.

It has yellowish-brown [[exfoliation (botany)|exfoliating bark]] that peels in woody scales rather than papery pieces like ''Acer griseum''.<ref name=gelderen/>
 
The [[leaf|leaves]] have a {{convert|2.5|–|6|cm}} [[Petiole (botany)|petiole]] and three leaflets; the leaflets are {{convert|4|–|9|cm}} long and {{convert|2|-|3.5|cm}} broad, with serrated margins, the central leaflet the same size as or slightly larger than the two side leaflets. The [[flower]]s are yellow, produced in small [[panicle|corymbs]] of three small flowers each, hence the name. The [[samara (fruit)|samaras]] are {{convert|3.5|-|4.5|cm}} long and 1.3–2&nbsp;cm broad, hairy, the nutlet with a woody shell.<ref name=xu/><ref name=gelderen/>
 
Even more than its relatives, three-flower maple has spectacular fall colour that may include brilliant orange, scarlet, purple and gold. It is one of the few trees to develop good fall colour in shade.<ref name=ncsi>[{{Cite web |url=http://www.ces.ncsu.edu/depts/hort/consumer/factsheets/trees-new/acer_triflorum.html |title=NCSi factsheet: ''Acer triflorum''] |access-date=2006-11-27 |archive-url=https://web.archive.org/web/20120205021147/http://www.ces.ncsu.edu/depts/hort/consumer/factsheets/trees-new/acer_triflorum.html |archive-date=2012-02-05 |url-status=dead }}</ref>
 
==Cultivation==
Line 28 ⟶ 22:
It grows at a slow to moderate rate and prefers moist, well drained soil; growth is often [[shrub]]-like in cultivation. It is relatively tolerant of drought and clay compared to its close relatives. It does not tolerate wet or over-compacted soil.<ref name=ncsi/> [[Plant propagation|Propagation]] is similar to that required for ''Acer griseum'' and the number of viable seeds is likewise very small.<ref name=gelderen/>
 
In [[Great Britain]], the largest specimens are up to {{convert|13|m|ft|0|abbr=on}} tall, and {{convert|60|cm|0|abbr=on}} trunk diameter (Tree Register of the British Isles). It has gained the [[Royal Horticultural Society]]'s [[Award of Garden Merit]].<ref>{{cite web|title=RHS Plant Selector - ''Acer trifolium''|url=httphttps://appswww.rhs.org.uk/plantselectorPlants/plant?plantid=4360292/Acer-triflorum/Details |accessdate access-date=723 JulyFebruary 20132020}}</ref> In the [[United States]], mature specimens can be seen at [[Arnold Arboretum]] in Boston, Massachusetts.
