At Kirstenbosch they make a beautiful display flowering with the pink diascias and white osteospermums of the Drakensberg. Anchusa capensis is easy to propagate from seed, which can be sown almost any time of the year. For a spring display, sow the seeds late summer and for a summer display sow the seeds in winter. Sow the seeds in a seed tray filled with well-drained soil and cover them with a thin layer of sand. Place the tray in the shade and water well.
Germination is usually very good and within a week or two.
The seedlings can be potted up as soon as they are big enough to handle and grown on before planting in the garden.
