Editing Four-leaf clover (section)

==Multi-leaved cultivars==
There are some cultivars of white clover (''[[Trifolium repens]]'') which regularly produce more than three leaflets, including purple-leaved ''T. repens'' "Purpurascens Quadrifolium" and green-leaved ''T. repens'' "Quadrifolium".<ref>Lord, Tony (ed), ''RHS Plant Finder 2006–2007'', (20th edition), Dorling Kindersley, London, 2006, p. 743. {{ISBN|1-4053-1455-9}}</ref> 

Some clovers have more spade-shaped leaves, rather than the usual rounded ones. This may be a genetic mutation. Some other genetic mutations in clovers include a rusty color on the leaves. ''Trifolium repens'' "Good Luck" is a cultivar which has three, four, or five green, dark-centered leaflets per leaf.<ref>[http://www.killerplants.com/weird-plants/20030710.asp Killerplants.com] {{webarchive|url=https://web.archive.org/web/20081011052758/http://www.killerplants.com/weird-plants/20030710.asp |date=2008-10-11 }} (photo)</ref>
