How to Grow Hibiscus in New Zealand
Roselle (Hibiscus sabdariffa) grows as a fast warm-season annual and does best in the warmer, frost-free north such as Auckland and Northland. Sow after all frost has passed, space the plants well, and harvest the red calyces once the flowers drop for tea, cordial and jam.
