Pot Size/Grade

Libertia grandiflora is a tidy, clump-forming NZ native that gives you clean, upright foliage all year, then pops up crisp white flowers in spring/early summer. It’s one of those “plant it once and enjoy it” options — great structure, easy care, and it fits almost anywhere from modern borders to native-style planting.

In South Island gardens, Libertia grandiflora is a favourite for edging paths, mass planting, underplanting, and adding a sharp, architectural look around shrubs. After flowering, you’ll often see orange seed capsules for extra interest. It also copes well with windy and coastal sites once established, so it’s handy for those tougher boundary gardens.

Spacing: Allow 50–70 cm between plants depending on how quickly you want the area to fill (closer for a faster “solid line” look).

How to establish your Libertia Grandiflora?

Light: Full sun to partial shade. Full sun gives tighter growth; part shade keeps foliage looking fresh in hotter spots.

Site: Handles wind and coastal exposure; ideal for open South Island gardens once settled in.

Soil: Likes well-drained soil, but is fairly adaptable (even tolerates heavier ground if it’s not sitting wet).

Watering: Water regularly through the first summer. After that, it’s generally drought-tolerant, only needing a drink in prolonged dry spells.

How to maintain your Libertia Grandiflora once established?

After flowering: Snip off spent flower stems to keep it tidy and push energy back into the clump.

Winter tidy: Pull or trim out old/damaged leaves at the base.

Divide if needed: Every few years, lift and divide clumps if they get crowded or you want more plants.

Frost: Generally hardy, but in very hard-frost pockets, young plants can benefit from a bit of shelter while establishing.
