Crug Farm say: An exciting find in the wilds of northern Vietnam, when we happened across a colony of this remarkable small species with narrow leathery leaves which were dark purple below, a trait that does not seem to show in many plants when young. Also remarkable on account of the dark blue fertile flowers (pink in alkaline soil) in the persistent inflorescences subtended by large sterile sepals which are white flushed blue on ageing. Best grown with some shelter from cold in a sunny to lightly shaded situation, in a moisture retentive drained fertile soil. This identity may well be modified.
