Dampiera linearis – Common Dampiera is a compact, quick-growing Australian native shrub prized for its brilliant cobalt-blue flowers and neat grey-green foliage. Flowering from spring into summer, and often from July to December in its natural range, this species creates an intense burst of colour in native gardens, rockeries, borders, embankments, and containers.

Growing to around 60 cm high and 60 cm wide, it has a naturally dense, spreading to upright habit, making it useful as a small feature shrub, groundcover, edging plant, or mass-planted colour display. It is more upright than Dampiera diversifolia, with attractive grey-green foliage and vivid flowers that stand out beautifully in cottage-style native gardens and coastal plantings.

Native to the south-west of Western Australia, Dampiera linearis occurs across regions including the Swan Coastal Plain, Avon Wheatbelt, Jarrah Forest, Mallee, Esperance Plains, Geraldton Sandplains, and Coolgardie. In cultivation, it performs well across many parts of Australia when planted in a well-drained, sheltered position with full sun to light shade.

Flowers

• Intense cobalt-blue to purple-blue flowers, often with a pale or yellowish centre.
• Main flowering period from spring to summer, with flowering recorded from July to December in its natural range.
• Flowers are approximately 1.5–2 cm wide and produced in small clusters.
• The bright blue colour provides excellent “wow factor” in native garden beds and containers.

Foliage

• Attractive grey-green to green foliage with a compact, dense habit.
• Leaves are generally obovate to elliptical, around 10–40 mm long.
• New growth may be softly hairy, becoming smoother with maturity.
• Forms a mound-shaped, spreading shrub suitable for edging and low garden structure.

Cultivation

Soil:

Requires well-drained soil. Suitable for sandy loam, loam, clay loam, and potting mix, provided drainage is reliable. In heavier soils, plant in a raised bed or mound to prevent waterlogging.

Sunlight:

Flowers best in full sun, but also grows well in light shade or dappled sunlight. A partly shaded, sheltered position is ideal in hotter inland areas.

Watering:

Water regularly while establishing. Once established, it tolerates dry conditions, though occasional watering during extended dry periods will keep plants looking their best.

Frost tolerance:

Tolerates light frost once established.

Drought tolerance:

Drought tolerant once established, making it suitable for dry native gardens, coastal cottage gardens, and some outback-style plantings where drainage is good.

Pruning:

Prune lightly after flowering to maintain compact growth and encourage a dense, tidy habit.

Fertiliser:

Apply a low-phosphorus native slow-release fertiliser in spring to support healthy growth and flowering.

Fire response:

This species can regenerate after fire and may regrow from underground suckering growth.

Uses

• Brilliant feature plant for native gardens and cottage-style gardens.
• Excellent for rockeries, borders, embankments, and retaining walls.
• Suitable for pots, large containers, and hanging baskets.
• Useful as a small groundcover or mass planting.
• Well suited to coastal gardens, courtyards, poolside plantings, and low-maintenance landscapes.
• A strong choice where intense blue flowers are needed for seasonal colour impact.

Habitat Value

Dampiera linearis supports garden biodiversity by attracting butterflies and other beneficial insects during its flowering season. Its dense, low foliage provides small-scale shelter for insects and ground-dwelling invertebrates, while the bright flowers add seasonal nectar and pollen resources to native plantings.

In mixed habitat gardens, Common Dampiera is especially useful as a lower-layer plant beneath taller shrubs, helping create a more complete and structurally diverse planting.

Growing Tips

Plant in a free-draining position in full sun to light shade. Dappled sunlight is ideal, particularly in hotter climates. Mulch after planting to help retain moisture and regulate soil temperature while the young plant establishes, but keep mulch clear of the crown.

If your garden soil is heavy or poorly drained, grow Dampiera linearis in a pot or raised bed using a free-draining native potting mix. It is a low-maintenance plant once established, needing only occasional watering in dry periods and a light prune after flowering to keep it compact and floriferous.
