See also the species specific Ceratostigma plumbaginoides Growing Guide.

Ceratostigma tends to flower from summer to autumn. It has pink or deep blue blooms, and has beautiful red or bronze leaves when flowering.

Due to their small size, leadwort and plumbago make ideal plants for rockeries, or as a fill in plant for stone walls.

How to Grow Ceratostigma

Ceratostigma require cold to germinate, so should therefore be sown out before the last frost of spring, or in the autumn. Seeds should be covered.

Ceratostigma prefers to grow in partially shaded or sunny parts of the garden.

They will grow in most soils, though best results will be got in an organic soil.

If you want to grow Leadwort or other Ceratostigma species from seeds indoors first, then they should be imbibed by first placing the seeds (within soil) in a black bag, then placing in the fridge for five or six weeks.

Seeds should then be sown out at a temperature of 15 Celsius (59°F). Plants normally take about one to three months to germinate.

Caring for Ceratostigma in the Garden

Ceratostigma seedlings should be transplanted in early spring. Use a spacing of 30 to 45 cm (12 to 18 inches).

Hardy species of Ceratostigma can also be planted out in the autumn.

Plants should be regularly watered, but do not drench them. They should be cut back in the autumn.
