Creeping Cinquefoil Potentillareptans
Creeping Cinquefoil is a perennial weed, more common on neglected lawns and turf in the UK. It is rarely a problem on well maintained lawns. It spreads by creeping stems which root at intervals.
The leaves are distinctive with five different segments with toothed edges. The flowers are yellow, again with five large fleshy petals which are visible from June to October.
