On their first encounter with this plant in our gardens, many people crave it. Strikingly lined and marbled, white-veined prickly leaves support many large heads of perfumed purple flowers. Best in poor soil where it can out-perform most others, but in good soil can tower frighteningly above you!
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.
