Shrubby
Cinquefoil Potentilla
fruticosa (Rosaceae)
This small,
bushy, deciduous shrub carries its clear-yellow flowers in abundance
over a long period from late spring to mid-autumn. Its twiggy stems
seldom grow much above 1.0 m in height and it has dark-green,
pinnate leaves, up to 4 cm long, composed of five or seven narrow,
oblong leaflets. The saucer-shaped flowers with a prominent centre
appear singly or in groups, each up to 1.6 cm across and male and
female flowers are carried on separate plants, although they are
difficult to distinguish from one another. The females produce
single-seeded fruits are in a clustered head.
Shrubby
cinquefoil is found on rock ledges and at the margins of lakes and
rivers, but is local to only two upland areas in northern England.
There are numerous garden cultivars.
This is a
valuable, versatile, free-flowering and long-flowering plant can be
useful for the border, for rock or gravel areas in a water garden,
or it can be used to make a low hedge. It prefers full sun in order
to flower well and a light, free-draining soil, although it is
tolerant of a wide range of soils. The plant does require moisture
and flourishes best where rainfall is dependable. Regular spring
pruning of the older shoots will keep the bush more compact. It can
be propagated from 10-12 cm cuttings of late summer shoots potted in
sandy compost in a propagator, or under polythene, or in a cold
greenhouse.
The flower
is visited by small insects including picture-winged flies.
