The Story
Plant Bio
Westringia is a genus of hardy, evergreen Australian shrubs closely related to rosemary, adapted to coastal cliffs and dry inland habitats. The plants feature narrow, whorled foliage and small, two-lipped flowers produced in the leaf axils throughout the year.
'Wynyabbie Gem' is a dense, rounded hybrid cultivar growing to 1.6 metres tall with soft grey-green leaves that are pale and hairy underneath. It produces light lilac-mauve to violet-blue flowers heavily clustered along the stems, peaking in spring but spot-flowering year-round.

Planting
How to Grow
- Plant in a full sun to partially shaded position in well-drained soil.
- Water moderately until established, then reduce supplementary watering to a minimum.
- Apply a low-phosphorus native fertiliser sparingly in spring if growth is slow.
- Tip-prune lightly after the main spring flowering flush to maintain a dense shape.
Pro Tip
Prune lightly and frequently after the main spring flush; cutting back into old bare wood prevents shooting and can shorten the plant's lifespan.

Care Guide
Do
- Ensure excellent soil drainage to prevent root rot.
- Prune lightly and regularly to maintain density.
- Use low-phosphorus native fertilisers sparingly.
Don't
- Do not prune hard into old, leafless woody stems.
- Do not overwater or allow the plant to sit in waterlogged soil.
- Do not shear heavily and repeatedly, as this shortens the plant's lifespan.
