HydrangeasDarwinia is a small evergreen shrub from Australia with fragrant needle-like leaves and unusual flowers framed by colourful bracts. In Ukraine it is a rare container plant for collectors: it cannot overwinter outdoors, but with the right care it flowers in spring and decorates a balcony all summer. Here are the main species and how to grow darwinia at home.
About the plant
The genus Darwinia belongs to the myrtle family, Myrtaceae (like myrtle and eucalyptus), and is named after the English physician and naturalist Erasmus Darwin, grandfather of Charles Darwin. There are about 70 species, almost all native to south-west Western Australia, and many are rare and protected.
Plants range from prostrate shrublets to shrubs 1–2 m tall. The leaves are small and narrow, rather like conifer needles, and in many species smell of lemon or mint and eucalyptus when crushed. The true flowers are tiny and tubular, gathered into heads; the colour comes from the bracts, which in some species form hanging red “bells”.
Popular species
Lemon-scented darwinia (Darwinia citriodora) — a spreading shrub up to 1–1.5 m with greyish leaves that turn reddish in the cold and smell of lemon. It bears small red-orange flower heads.
Darwinia homoranthoides — a low species with sprawling branches, good for rock gardens and wide containers.
Mountain bells (Darwinia oxylepis, D. macrostegia) — the most ornamental species, with red or red-and-white bells of bracts hanging from arching stems. They are rare and protected in the wild and grown mainly by collectors.

Care in a pot
Light. The sunniest spot in the house, and a balcony or terrace from May to September. In shade darwinia gets leggy and does not flower.
Soil. Light, acidic and free-draining: acidic peat, coarse sand and perlite with a drainage layer at the bottom. Heavy garden soil is not suitable.
Watering. Regular but moderate — let the top layer dry out. The roots cannot stand waterlogging, but a completely dry root ball is also dangerous. Use soft, settled or rain water, and mulch the surface with bark in summer to keep the roots cool.
Feeding. Like many Australian plants, darwinia is sensitive to phosphorus. Feed rarely and weakly with a fertiliser for ericaceous plants or a low-phosphorus one. Gentle options are covered in natural fertilisers for houseplants.
Winter. The plant is not frost-hardy. In winter it needs a bright, cool place at 5–12 °C, such as a glazed loggia or cold porch, with reduced watering. In a warm room with dry air darwinia weakens and does not set buds.
Pruning and repotting. Trim the shoots lightly after flowering to keep the plant bushy. Repot in spring when roots fill the pot, without burying the root collar.
Propagation. Take semi-ripe cuttings in summer and root them in peat and sand under a cover; rooting takes several weeks.
FAQ
Can darwinia grow in a garden in Ukraine?
Only in a container over summer — it will not survive the winter outdoors.
When does darwinia flower?
In cultivation usually from late winter to early summer, after a cool, bright winter rest.
Why is my darwinia dropping leaves?
Most often because the roots dried out or stayed too wet, or because it spent the winter somewhere warm and dark.
