Sempervivum heuffelii 'Bros' is a cold hardy succulent from the Crassulaceae family, native to mountain regions of southeastern Europe. This alpine succulent has adapted to rocky alpine terrain and grows as a frost hardy perennial outdoors. It needs little ongoing attention once established.
'Bros' forms tight, geometric rosettes with thick, fleshy leaves in crimson red tones that deepen in full sun. The rosette grows in a clustering habit, gradually spreading into a dense mat of offsets that fills containers, troughs, and rock garden gaps. Leaf edges show fine ciliation, adding subtle texture to the bold, saturated tones of each rosette.
It produces flowers typical of the genus, though blooms are secondary to the foliage display. 'Bros' is pet safe, so you can display it freely on low shelves, patios, or anywhere curious cats and dogs roam. It does produce pollen and can carry allergens, which is worth knowing if you have sensitivities in the household.
Move it outside to a sunny balcony, rock garden, or container for summer and autumn. It survives up to ten days without water and tolerates dry heated indoor air. You can leave it outdoors through autumn and into winter across most of the United States.
