Lithodora is a low, ground-covering perennial which remains evergreen in mild winters of zones 5 and 6, and fully evergreen in zone 7. Its prostrate, spreading branches lie on the ground and overlap edges of elevated beds, patios, and pots.
Description of the plant:
Heavenly Blue is a perfect name for this lithodora which produces a plenty of small, sky blue flowers from late April until early June, and sporadically throughout the summer. Leaves are thick, deep green, and the plant forms a neat cushion with partly erect twigs in the centre.This lithodora does best in acid soil unlike other varieties. It needs well-drained soil and full sun. It will look great in a rockery as well as an edging plant of a perennial border. We mix it with low, compact shrubs in borders mulched with pebbles. It can take windy locations that tend to dry out in summer – its thick leaves absorb enough water that the plant can use during dry spells of summer. Hardiness varies with soil conditions but usually lies between -25°and -27°C (USDA zone 5b-6).
