Overview

Monotoca scoparia is an evergreen shrub growing 1.5-6.5 feet (0.5-2 m) tall and 1.5-5 feet (0.5-1.5 m) wide, with many erect wiry branches forming a dense broom-like outline. The leaves are small, narrow, and linear, 0.2-0.5 inch (5-12 mm) long, crowded along the stems, stiff, and tipped with a sharp point, dark green above and paler beneath. Tiny tubular white to cream flowers about 0.1 inch (2-3 mm) long hang singly or in short clusters in the leaf axils, mainly in autumn and winter. The flowers are followed by small fleshy fruits about 0.1 inch (3 mm) long that ripen yellow to orange. Growth is slow, and plants build up a dense twiggy structure over several years. The pointed leaves are prickly to handle. The species needs sharp drainage and acidic soil and is sensitive to phosphorus, which makes it slow to establish in gardens.

Native Range

Native to south-eastern Australia, including New South Wales, the Australian Capital Territory, Victoria, and Tasmania. Grows in heath, dry sclerophyll forest, and woodland on sandy and rocky acidic soils, often on ridges and exposed slopes.

Suggested Uses

Grown in native heath gardens, rockeries, and revegetation on acidic sandy soils, spaced 2-4 feet (0.6-1.2 m) apart. Used as a low screen or filler among other heathland plants. Its prickly foliage and need for sharp drainage limit wider garden use.

How to Identify

Identified by dense wiry broom-like branches crowded with small stiff linear leaves 0.2-0.5 inch (5-12 mm) long ending in a sharp point. The tiny white to cream tubular flowers 0.1 inch (2-3 mm) long sit in the leaf axils. Distinguished from Leucopogon spp. species by its single-seeded fruit and the nearly hairless inner surface of the flower tube.

Care & Maintenance

Care Guide

Grows in full sun to light shade on sharply drained sandy or rocky acidic soils; it fails in heavy, wet, or limy ground. Water lightly during establishment, after which plants tolerate dry conditions. Apply only low-phosphorus fertilizer, as members of the heath family are sensitive to phosphorus. Plants are frost hardy in their native range. Root rot from Phytophthora spp. can kill plants in poorly drained soil. The species is slow to establish and is uncommon in cultivation.

Pruning

Tip-prune lightly after flowering to keep the bushy form, as the wiry growth can become open with age. Hard cutting into bare wood is slow to reshoot. Plants need little routine pruning.
