Growth Stages

1

Seedling

3-4 weeks

Tiny seedlings with fine needle-like cotyledons emerging from seed

Keep soil barely moist, provide bright light, avoid waterlogging; germinates in 10-14 days at 65-75°F

2

Juvenile Growth

2-3 months

Young plant developing characteristic narrow, linear foliage in soft green tones

Maintain moderate watering; apply dilute balanced fertilizer monthly; pinch tips to encourage bushiness

3

Vegetative Development

6-12 months

Established shrub with dense, feathery foliage structure; no flowers yet

Reduce watering frequency as plant matures; prune lightly to maintain compact form; fertilize sparingly

4

Flowering

4-6 months (spring to early summer)

Small, delicate tubular flowers appearing along stems in white, pink, mauve, or purple hues

Flowering is prolific in spring and summer; deadhead spent flowers to encourage continuous blooms; maintain consistent light exposure

5

Maturity & Maintenance

Ongoing

Full-grown shrub (3-5 feet) with dense foliage and year-round flowering potential

Prune in late winter or early spring to maintain shape; minimal fertilizer needed; water only during drought

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.
