Growth Stages

1

Seedling

4-6 weeks

Tiny seedlings with sparse, fine foliage emerge; growth is slow initially

Keep soil barely moist (not wet); provide bright light; avoid damping-off by ensuring excellent drainage and air circulation

2

Establishment

3-6 months

Young plant develops deeper root system and basal branching; foliage becomes denser and needle-like

Water deeply but infrequently to encourage deep rooting; do not fertilize; protect from excessive moisture and cold winds

3

Vegetative Growth

6-12 months

Shrub fills out with silvery-green needle foliage; branching increases; plant becomes more compact and rounded

Minimal supplemental water needed; light pruning to shape; avoid nitrogen-rich fertilizers which promote soft growth susceptible to disease

4

Flowering

3-6 months (often winter through spring)

Purple tubular flowers appear along branch tips; blooming is prolific and often extends over several months

Do not deadhead if self-seeding is desired; continue drought conditions; provide full sun for maximum flower production

5

Mature Specimen

Ongoing

Fully established shrub reaches 3-4 feet tall and wide with dense branching; flowering becomes predictable and abundant annually

Prune only to maintain shape or remove dead wood; extremely drought-tolerant; frost-hardy once established

Companion Planting

Plan your garden →

Plant with:

Lavender Rosemary Santolina Teucrium (Germander) Catmint (Nepeta) Salvia Ornamental grasses (Stipa, Pennisetum) Agapanthus

Avoid planting near:

Plants requiring frequent watering Species that prefer humid conditions High nitrogen-loving plants

Common Pests

  • Prevent through excellent drainage and reduced watering in winter; no chemical cure—remove infected plants

  • Rare; occasional overhead misting or neem oil spray if severe; improves air circulation

  • Inspect regularly; remove by hand or apply horticultural oil spray in early morning or evening

Uses

🌿

Drought-Tolerant Landscape Design

Ornamental

The purple form serves as a striking focal point in xeriscape gardens, water-wise landscapes, and Mediterranean-style plantings. Its fine foliage texture and vibrant purple flowers provide color and visual interest with minimal resource input. [source]

🦋

Pollinator and Bird Attraction

Wildlife

Tubular purple flowers attract hummingbirds, native bees, and other pollinators over an extended season. The nectar-rich blooms support pollinator populations in arid regions where food sources may be limited. [source]

🏠

Cut Flower Arrangement

Household

Purple flower sprays can be cut for short-lived floral arrangements. The fine-textured foliage also provides elegant backing and volume in mixed bouquets. [source]

🎨

Dried Flower Material

Craft

Flower stems can be dried for long-lasting arrangements and craft projects. The purple color holds well when air-dried in a cool, dark location. [source]

Harvest Tips

Eremophila glabra is an ornamental shrub not typically harvested for foliage or flowers. Collect seeds from mature flower heads in late season if desired for propagation—allow seed pods to dry on plant, then collect and store in cool, dry conditions.

Fun Facts

  • 🌱 Eremophila glabra is endemic to arid and semi-arid regions of inland Australia, where it has evolved remarkable adaptations to survive extreme heat, drought, and poor soils—making it a living example of botanical resilience.
  • 🌱 The common name 'Emu Bush' derives from the fact that emus and other Australian wildlife consume the fruits and seeds, dispersing them across the landscape in natural ecosystems.
  • 🌱 The purple form is highly variable in cultivation; some plants from seed may revert to other color forms, making each plant potentially unique—a characteristic prized by collectors of Australian native plants.
