Petrophile teretifolia, also known as Conesticks, is a beautiful and distinctive Western Australian native shrub belonging to the Proteaceae family. It is admired for its fine, needle-like foliage and rounded, cone-shaped clusters of soft yellow flowers that bloom in spring and early summer. These charming flowers are rich in nectar and attract native bees, butterflies, and small birds, making it a valuable addition to wildlife gardens.

Petrophile teretifolia is native to the south-west of Western Australia, where it grows naturally in sandy or gravelly soils within heathlands and open woodland. It is well adapted to dry conditions and nutrient-poor soils, making it an ideal choice for low-maintenance Australian native gardens.

This species is increasingly used in native garden design for its fine texture, drought tolerance, and striking flower heads. The dried cones retain their shape and colour for a long time, making them attractive for use in natural floral arrangements. Its compact size and hardy nature make it suitable for both home gardens and larger landscape plantings.

How it Grows
Petrophile teretifolia is a small to medium shrub, usually reaching around 1 to 1.5 metres in height and width. It prefers full sun and very well-drained soils, particularly sandy or gravelly types. Once established, it is highly drought tolerant and also handles light frost. Minimal pruning after flowering will keep the plant tidy and encourage fresh growth.

How to Grow From Seed:

Like many Australian natives, Petrophile seeds have a hard outer coating and benefit from pre-treatment. Soak seeds in warm water for 24 hours before sowing to help improve germination.

Sow seeds in late autumn or winter into a seed-raising mix designed for native plants.

Cover lightly with soil or vermiculite and keep moist but not waterlogged.

Germination can take several weeks to several months, depending on temperature and moisture.

Once seedlings are large enough to handle, transplant them into pots and grow them on before planting into the garden in a sunny, well-drained position. Avoid fertilisers high in phosphorus, as Proteaceae plants are sensitive to it.
