POLYGONUM BISTORTA 'SUPERBA'
In stock
Description
Sizeable, cool pink "bottle-brush" heads are produced over an extended period during May and June over strong clumps of broad basal leaves. Graham Stuart Thomas says, "Useful and beautiful" and indeed its Latin name is most appropriate.
Sowing Advice
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.
