Calluna vulgaris 'County Wicklow' is a compact form of Scotch heather valued for year-round evergreen texture and a long season of color from budded, spike-like flower racemes. You can use it as a low edging shrub, in rock gardens, and in masses where its fine, scale-like foliage reads as a soft mound even when not in bloom.
Give it sun for best flowering, with some afternoon shade helpful in hotter sites. Mature size for this selection is typically around 10-12 inches tall, with a low, spreading habit that fills in over time. Flower color is commonly in the purple to lavender range, and plants can also show bronzy tones in colder weather.
Plant in consistently acidic, well-drained soil. Avoid heavy clay and standing water, and aim for an organic, sandy or loamy mix if you are amending. Water regularly the first season to establish a strong root system; once established, heather handles short dry spells better, but it still performs best with even moisture and good drainage.
Light pruning after flowering helps keep plants dense. Shear lightly, staying in green growth and avoiding hard cuts into old wood. A winter mulch can help protect roots in colder climates and reduce heaving during freeze-thaw cycles.
