Ulex minor
dwarf gorse
Western Europe (Britain, France, Iberia)
Overview
Ulex minor, dwarf gorse, is a low, spiny, evergreen shrub in the pea family (Fabaceae) growing 4-39 inches (10-100 cm) tall, usually forming a spreading, somewhat sprawling mound. Like other gorses it has no true leaves on mature growth; instead the green stems and weak, soft-tipped spines under 0.4 inch (10 mm) long carry out photosynthesis and give the plant a dense, prickly texture. From July to November it bears small yellow pea flowers about 0.3-0.4 inch (8-10 mm) long, scattered along the stems, later in the year and with softer spines than common gorse (Ulex europaeus). The flowers ripen into short, hairy pods that split to fling out the seeds. It grows on dry, acidic, sandy heaths and is largely confined to lowland heathland in western Europe, where it is a characteristic plant of late-summer heath alongside heather. As a legume it fixes nitrogen through root nodules and copes with poor, infertile soil. One limitation is its need for acidic, free-draining ground and full sun, so it fails on chalky, heavy, or shaded sites.
Native Range
Ulex minor is native to western Europe, from southern Britain through western France to the Iberian Peninsula, where it grows on lowland acidic heaths. It is largely restricted to sandy, free-draining heathland soils.Suggested Uses
Used in heathland restoration and on dry, acidic banks and informal wild plantings where its spiny, nitrogen-fixing growth suits poor sandy soil. The late flowers give nectar for bees, and the dense growth shelters heathland birds and insects.How to Identify

Reaches mature size in approximately 3 years
Bloom Information
Flowering runs from July to November, peaking in late summer and autumn, later than the spring flush of common gorse. The small yellow pea flowers are scattered along the green spiny stems and are visited by bees. Short hairy pods follow and split explosively in dry weather to scatter the seed.

Care & Maintenance
Care Guide
Ulex minor grows in full sun on dry, acidic, sandy, free-draining soil of low fertility, and as a nitrogen-fixing legume it asks for no feeding. It is hardy in roughly USDA zones 7 to 9 and keeps its green spiny stems through winter. It fails on chalky, heavy, wet, or shaded ground, which limits it to open heathland conditions. On heaths it is maintained by periodic cutting or controlled burning that keeps the heath open and renews young growth. It is raised from seed, which germinates more readily after scarification. Mature plants resent transplanting because of a deep root system.Pruning
Old, leggy plants are cut back hard in spring to bring fresh growth from the base, as gorse regenerates well after cutting. On heathland it is managed by rotational cutting or burning. Light trimming after flowering keeps individual bushes compact.Pruning Schedule
