How to grow Cortaderia splendens in NZ

Cortaderia splendens grows best in full sun with fertile free draining soil. Prepare the planting site with compost before planting to encourage healthy root development and water regularly while the plant establishes. Once established it tolerates dry periods well, although occasional watering during extended dry weather encourages stronger growth. Choose an open location where the foliage and flower plumes can develop freely.

Cortaderia splendens care tips

Cortaderia splendens is easy to maintain and requires very little attention once established. Feed during spring with a quality slow release fertiliser to encourage vigorous new foliage. Remove old leaves and spent flower stems as required to maintain a tidy appearance. Apply mulch around the base to conserve soil moisture while keeping it clear of the crown.

Cortaderia splendens size, spacing, and growth rate

Cortaderia splendens typically grows to around two to three metres tall including the flower plumes and spreads to about two metres wide. Space plants approximately two metres apart to allow room for mature growth and good air movement. Growth is moderate to fast under favourable conditions, producing a bold clump that becomes increasingly impressive each season.
