Hypericum calycinum

How to grow Hypericum calycinum in NZ

Hypericum calycinum grows best in full sun or partial shade with well drained soil, though it adapts well to many soil types throughout New Zealand. It performs particularly well in areas where reliable groundcover and erosion control are required. Water regularly during establishment to encourage strong root development and healthy spreading growth. Adding organic matter to the soil before planting will improve performance. Once established, this hardy plant tolerates dry conditions well and requires very little ongoing maintenance.

Hypericum calycinum care tips

Hypericum calycinum is an easy care plant that benefits from occasional watering during extended dry periods while establishing. Apply mulch around young plants to help retain moisture and suppress weeds. Feed with a balanced fertiliser during spring to encourage dense foliage and abundant flowering. Trim plants lightly after flowering if needed to maintain shape and encourage fresh growth. This vigorous groundcover spreads steadily and can be pruned back to control size or keep pathways and borders tidy.

Hypericum calycinum size, spacing, and growth rate

Hypericum calycinum is a fast growing evergreen groundcover that typically reaches around 30 to 60 centimetres tall and spreads widely over time in New Zealand conditions. Plants should be spaced approximately 60 centimetres apart to achieve dense coverage quickly. Growth is strongest during spring and summer when plants receive regular moisture and sunlight. The spreading stems form a thick carpet of green foliage with bright yellow flowers that provide excellent weed suppression and seasonal colour in landscape settings.
