Casuarina Cousin It (Casuarina glauca ‘Cousin It’) is a popular choice for Central Coast gardens. Insignificant flowers, with foliage plant, fine weeping form colouring. As a Central Coast garden centre based right here in Erina Heights, we know what thrives in our warm, humid summers and mild, coastal winters. It prefers full sun to part shade and low to moderate, drought tolerant once established. Wonderful low, weeping groundcover form; very hardy in coastal conditions.
