Ceratostigma plumbaginoides, the Hardy blue-flowered leadwort, is originally from western China. It’s a deciduous, low-growing woody perennial with spreading roots. It will grow to approximately half a metre tall, with its branches spreading out to cover a similar area. It forms a mat of simple leaves, which usually give fantastic autumn colour, and produces clusters of rich blue flowers in late summer and into autumn. It is a good plant for border edges and can also do well in containers due to its small habit. It likes a fertile, moist but well-drained soil and a fairly sheltered position, although it is generally hardy. It is happiest in full sun, but also quite good in shadier spots. Once it has become established, it is also quite drought-tolerant. It can be pruned after flowering in the autumn. You can find it near the South Lodge in the Parks.
