Leionema sp. 'Colo River’

First discovered in the early 1960s, this species was not rediscovered until 2000, when Tony Rodd, a botanist formerly of Royal Botanic Gardens, Sydney, was undertaking willow removal on the Colo River, and noticed a small population of these shrubs while having lunch.

It shows considerable horticultural potential and we are trialling it in a range of soils.
