Ceratostigma plumbaginoides

GardenAward

Hardy plumbago

Perfect for a rockery

A small, bushy, hardy plumbago growing to 30cm (1ft) in height with a similar spread. Herbaceous rather than shrubby it dies down in winter producing a mound of stems and fresh green leaves each year which are studded with sapphire blue flowers from midsummer. An ideal plant for the small garden or the front of a sunny border. The flowers are very attractive to butterflies.

Where?

Plant in full sun at the front of a border, in gravel, alongside paving or in a pot. The warmer the situation, the more prolific the flowers.

How?

Any well-drained soil. Good on poor soils and chalk and ideal for gravel, gaps in paving or on stone walls. Cut back to the ground in winter.

The seeds were brought back by a soldier as the British army moved into Beijing - so the story goes

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
