This cultivar Hylotelephium telephium 'Purple Emperor' is a succulent perennial whose original parents are native to Eurasia. Hylotelephium telephium subsp. maximum 'Atropurpureum' was one parent, although the other is still a mystery. Its common name 'Purple Emperor' was named after a rare Eurasian butterfly Apatura iris. This cultivar was first spotted as a seedling by Graham Gough, of Marchants Hardy Plants, growing in his parents' garden in East Sussex.
It is a fast growing, compact, deciduous, herbaceous perennial which grows >50cm tall and has broad, plum-black leaves which are whorled in threes at the top of each erect dark red stem. Rounded clusters of small, pale purplish-pink flowers develop in late summer. These heads of tiny flowers are very attractive to bees, butterflies and hoverflies.
