This uncommon plant is endemic to southern California, where it grows in shady forested areas near streams in the mountains. It bears a dense array of many small white flowers, each with five tiny pointed sepals and five larger oval petals and reaches up to a meter tall on a thin wiry stems.
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.
