Quite an incredible plant for the back of the border, we had never previously heard of this plant or family! Tall, strong, fabulous, arching, cane-like stems sprout large, pendulous, terminal sprays of creamy-yellow-green flowers, and are clad in palmate leaves resembling the famous drug! This is perhaps the tallest herbaceous perennial you can grow, and is yet another reliable "baffle-the-expert" plant.
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.
