This rare and strikingly attractive, strongly aromatic plant, comes from the mountains of central and southern Europe and bears jaggedly cut, glossy green foliage, and creamy umbels turning lime green. In late spring it produces large numbers of yellowish-white, sweetly fragrant flowers, which in turn form large, intriguing heads of sizeable, twisted seeds.... And yes, what a brilliant name!
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. Plant out in a well-drained, sheltered position.
