With its clusters of creamy white flowers, this must be one of South Africa's prettiest indigenous perennials. Growing in small clumps, the countless flower heads stand on long, naked stems above the finely divided, almost fern-like leaves, which form opposite each other along the lower part of the stems, gently moving with the slightest breeze. On warm summer days, butterflies cover these filigree mounds for this is one of their favourite nectar plants. A long succession of beautiful flowers appears from early spring to the middle of summer.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
