Ceratostigma plumbaginoides (hardy blue-flowered leadwort) is a member of the Plumbaginaceae family. This perennial exhibits a clump forming growth habit and is characterised by its deciduous foliage. It has a hardiness rating of hardy (cold winter [-15 to -10ºc]) and is hardy throughout most of the UK, even in severe winters. May not withstand open or exposed sites or central/northerly locations, with many evergreens suffering foliage damage and plants in pots being at increased risk.
When fully mature, Ceratostigma plumbaginoides can reach an ultimate height of 0.1–0.5 metres and a spread of 0.1–0.5 metres. For optimal growth, it prefers an east–facing or south–facing aspect and a sheltered position. It thrives best in chalk, clay, loam, or sand soil types and should be placed in full sun.
