William Curtis, The Botanical Magazine — 68
“ Like most of the Houseleeks it is best kept in a pot, or it will grow well and appear to great advantage on a wall or piece of rock-work; the more it is exposed to the sun, the more colour will enliven its stalks and foliage, and the more brilliant will be its flowers; the latter make their appearance in July.It is propagated by offsets which it sends forth in abundance.It is no uncommon practice to treat this beautiful species of Houseleek, as a native of a warm climate ”
