Crassula sarcocaulis 'Alba' is the white-flowering form of Crassula sarcocaulis, the only truly hardy Crassula in the British climate. It will reliably survive most UK winters, usually losing some of its leaves in the coldest periods. It can withstand temperatures down to at least -12C and at these lows it starts to defoliate heavily before sprouting again from its woody tree-like stems in the Spring. It also regularly self-seeds and it is not uncommon to find hundreds of tiny Crassulas growing in and around the parent plant once the warmth of Spring has begun.

Endemic to the dry scrubland, high veldt grasslands and rocky montane slopes of Southern Africa, Crassula sarcocaulis 'Alba' forms a small woody multi-branched shrub that grows 50-80cm high. It favours free-draining pockets of soil and crevices in amongst the rocks. Crassula sarcocaulis 'Alba' is very drought tolerant but it is also extraordinarily tolerant of typically wet British conditions and will survive the winter even when wet. 

In July, it covers itself in a blanket of tiny white buds that open to exquisite - if somewhat odd-smelling - white flowers in cluster-like cymes at the end of each leafy branchlet.

This is the white-flowering form given to us by Tropical Britain customer, Ricky Berg. Thankyou, Ricky!
