How to grow Wisteria ‘Blue Sapphire’ in NZ

Wisteria ‘Blue Sapphire’ grows best in full sun to maximise flowering, though it will tolerate light shade. Plant into fertile free draining soil and provide a sturdy support structure such as a pergola, fence, or archway. It performs well across most NZ regions. Water regularly during establishment, then reduce once settled. Training young shoots early helps create a balanced framework and improves flowering coverage.

Wisteria ‘Blue Sapphire’ care tips

Wisteria ‘Blue Sapphire’ benefits from regular pruning to manage growth and promote flowering. Prune immediately after flowering and again in late summer to shorten vigorous shoots. Water during extended dry periods, especially in the first few seasons. Feed in spring with a balanced fertiliser, avoiding high nitrogen products that encourage leafy growth rather than flowers.

Wisteria ‘Blue Sapphire’ size, spacing, and growth rate

Wisteria ‘Blue Sapphire’ typically grows to around 6 to 8 metres tall with support and spreads several metres wide. It has a moderate to vigorous growth rate once established. Space plants about 4 metres apart when planting along structures to allow for airflow and canopy development. Its size suits medium to large gardens.

Wisteria ‘Blue Sapphire’ is ideal for covering pergolas, archways, fences, and large trellises in NZ gardens.
