Ceratostigma

Ceratostigma Plumbaginoides (Plumbago larpentae)
Leadwort

Planting:

Set plants 15 to 18 inches apart. Ceratostigma will grow virtually anywhere, in good soil or poor, in sun (preferable farther north) or shade, heat or cold.

Maintenance:

We recommend a light winter mulch. As plants spread rapidly, frequent dividing may be necessary; this is best done in spring.

Zones:

Zones 5 to 9.
