Mirabelle Boronia

Mirabelle Boronia (Boronia hybrid 'Mirabelle') is a compact, slender native shrub that stops at just 60cm tall and wide. It is named after the sweet French plum, and its flowers match: deep plum-pink bells ring through late winter and early spring over small, aromatic evergreen leaves. At about knee height it fits almost anywhere, from a courtyard pot to the front of a sheltered bed.

Why you'll love it

• Plum-coloured bells. Deep pink flowers with a rich plum tone arrive in late winter and early spring, when gardens need an extra pop of colour.
• Truly compact. At 60cm by 60cm it is the right scale for pots, edges and small beds, and it never needs staking or heavy shaping.
• Aromatic foliage. The tiny evergreen leaves are aromatic year round, so the plant is worth brushing past even out of flower.
• Lightly scented flowers. A gentle fragrance drifts from the bells on mild winter days.
• Pots and wildlife gardens. It does well in large containers and suits wildlife-friendly planting.

Where it works best

Courtyard pots. One plant to a 30cm pot of native potting mix is plenty. Group two or three pots by a doorway for a winter display you pass every day.

The front of a border. Plant 50cm apart at the front of a sheltered bed, so the plum bells are seen first and taller shrubs sit behind.

Wildlife gardens. Mixed in with other small natives and low perennials, it fits a relaxed, habitat-style planting.

Growing Mirabelle Boronia in Australia

Position and climate. Dappled shade in a sheltered position, out of hot afternoon sun. Mirabelle tolerates a light frost. Native boronias like light, moist, neutral to acid soil, so look for the cooler side of the house or garden rather than a baking wall.

Soil. Light, free-draining and slightly acid, with generous organic matter. In pots, use a native potting mix. Gravel mulch around the young tube keeps the roots cool and moist as it settles.

Water and feed. Even moisture is the whole game: never bone dry, never boggy, with extra water in hot spells. After flowering, apply a slow release native fertiliser and fresh mulch.

Pruning. Prune lightly once the flowers have finished, and cut flowering stems for a vase. A small plant needs only a small trim.
