Harvest Tips
Westringia is not harvested for food or commercial purposes. Cuttings can be taken year-round for propagation, with semi-hardwood cuttings in spring-summer rooting most readily in 4-6 weeks. Cut 2-3 inch stems, remove lower leaves, dip in rooting hormone, and insert into well-draining propagation medium.
Fun Facts
- 🌱 Westringia is native to the coastal regions of New South Wales and Queensland, Australia, and is sometimes called 'Coastal Rosemary' due to its superficial resemblance to rosemary, though it's not closely related botanically.
- 🌱 The name 'fruticosa' means 'shrubby,' reflecting its dense, bushy growth habit; the genus Westringia contains over 30 species, many of which are endemic to Australia.
- 🌱 Westringia is exceptionally salt-tolerant and thrives in coastal gardens exposed to salt spray, making it an ideal choice for seaside landscaping where many ornamental plants struggle.
