I am wondering why this interesting, cold hardy, beautiful and excellent rockery plant is absolutely ignored. Is there a secret?
Last year I easily germinated seeds and grew the seedlings into a fine clump by the end of the season (the seedlings pot was planted in the rockery as a whole in May). I am confident it will make it well over the winter, and maybe even produce a few flowers. Meanwhile, someone else already knows why is it such a ‘secret’ species please?
