Helianthemum nummularium 'Wisley Pink'

Perennial sub-shrub cultivar of the Cistaceae family, obtained and selected in the gardens of the Royal Botanic Gardens of Wisley, in England, from which it takes its name. Like most cultivars of the genus, it is derived from selections or hybridizations from the European type species and its varieties.

It forms a bushy and spreading clump, 20 to 30 cm in height, with well-branched stems bearing foliage of small narrow, gray-green, slightly tomentose leaves, which provide a discreet and matte background highlighting the delicacy of the flowers.

These are of a very soft pale pink, almost pastel, with an orange center surrounded by yellow stamens, carried in loose and generous clusters. The particularly tender hue of this cultivar distinguishes it from the more intense pink forms of the genus; some flowers may appear almost whitish when fading, further accentuating the airy effect of the bloom.

In cultivation, flowering extends from May to July, with a possible partial resurgence if the plant is lightly cut back after the first wave of flowers.

It thrives in well-drained soil, poor to moderately fertile, in full sun. A light cutback after flowering helps maintain the compactness of the clump and prolong its longevity. Perfectly hardy in our climates.
