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.
