"Large Yellow Loosestrife" has been a cottage garden favourite since ancient times. Perennial roots produce stiff spikes of funnel-shaped golden flowers which appear throughout the summer and early autumn. A superb, long-lived cottage garden flower that also does well by water!
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.
