Eremophila 'Summertime Blue'

The Story

Plant Bio

Eremophila is a diverse genus of evergreen Australian shrubs and trees adapted to arid and semi-arid environments. These plants are characterised by their resinous or hairy foliage and tubular flowers adapted for pollination by native birds.

'Summertime Blue' is a naturally occurring hybrid between Eremophila divaricata and Eremophila polyclada that forms a large, spreading shrub with a weeping, fountain-like habit. It produces pale lilac to violet-blue tubular flowers from deep purple buds, primarily during summer but extending from spring to autumn.

Uses & Benefits:

Ornamental UsesProduces a dense, weeping canopy of fine green foliage covered in pale lilac-blue flowers over an extended period from spring to autumn.
Practical UsesHighly drought-tolerant and uniquely capable of thriving in heavy, alkaline clay soils where other desert species fail.
Ecological BenefitsThe nectar-rich tubular flowers provide a highly valuable food source for native Australian honeyeaters and beneficial insects.

Planting

How to Grow

  1. Choose a planting site in full sun to light shade with well-drained soil, though heavy clay is tolerated.
  2. Dig a hole twice the width of the root ball and of equal depth, ensuring the plant sits at its original soil level.
  3. Water thoroughly after planting to settle the soil, then apply a coarse organic mulch to conserve moisture.
  4. Provide minimal supplementary water once established, as the root system is highly drought-tolerant.

Pro Tip

Prune the canopy lightly immediately after the main summer flowering flush; cutting back into old, leafless wood where epicormic buds are absent will prevent regrowth and leave permanent bare patches.

Keep It Thriving

Care Guide

Do

  • Prune lightly every year immediately after summer flowering to maintain a dense, rounded form.
  • Grow in heavy clay or alkaline soils where other Eremophila species usually fail.
  • Ensure the planting site receives maximum daily sunlight to promote heavy flowering.

Don't

  • Do not prune heavily into old, bare wood that lacks active green leaves.
  • Do not overwater once the root system is established, as this species thrives on dry conditions.
  • Do not plant in deep shade, which causes a sparse, straggly habit and reduces flowering.
