The Ceratostigma plumbaginoides is an ideal addition to any garden. With its beautiful blue flowers and compact habit, it is sure to attract attention. This hardy perennial thrives in full sun and can tolerate a wide range of soil conditions, as long as it is moderately fertile and well-drained. 
When it comes to caring for this plant, pruning is essential. In early or mid-spring, cutting back the flowered shoots to within 2.5cm of the old growth will promote healthy growth and blooming. After pruning, it is recommended to apply a generous 5-7cm mulch of well-rotted garden compost or manure around the base of the plant. This will help retain moisture and provide essential nutrients for optimal growth.
