The Xanthorrhoea Johnsonii is a dramatic and spectacular species of grass tree native to Western Australia. It is a slow-growing perennial shrub with thick blackened trunks topped by a dense grassy clump of leaves. It takes decades to reach full maturity and can live up to 600 years. As the flower spike is the active growth point for the tree, after flowering, it is natural for the tree to remain dormant and not produce new leaves for months or even years. Xanthorrhoea johnsonii is an ideal choice for a courtyard, outdoor dining or entertainment area or around the pool. Rows of identical straight Xanthorrhoea johnsonii, like sentinels, are ideal in formal settings. To encourage continuous growth remove the flower spike as soon as it appears and feed the leaves and roots with seaweed fertilisers. Soil: Grows naturally in sand, loam or gravelly soils. Conditions: Open, sunny position. Size: Height 4m x width 1.5m
