This little known but most welcome newcomer pushes up bright spikes of deep violet blue flowers over a very long period on compact fragrant leaved plants. It will grow anywhere but thrives best in a hot, well-drained position.
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.
