What Is the Two-lobed Leionema?
Two-lobed Leionema (Leionema bilobum) belongs to the Rutaceae family within the Leionema genus. Two-lobed Leionema is native to south-eastern Australia. Two-lobed Leionema is also known as Two-lobed Waxflower.
Two-lobed Leionema displays a compact, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Two-lobed Leionema produces small clusters of white or pink flowers.
Leaf size: approximately 2 inches.
How Often Should You Water a Two-lobed Leionema?
Water a young or newly planted Two-lobed Leionema every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

What Soil Mix Works Best for a Two-lobed Leionema?
Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Two-lobed Leionema to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Two-lobed Leionema?
Feed Two-lobed Leionema every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.
Stop feeding by late summer so new growth can harden before winter.

Where Should You Plant a Two-lobed Leionema?
Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.
Two-lobed Leionema is suited to USDA Zone 12a.
Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.
How Far Apart Should You Plant a Two-lobed Leionema?
Two-lobed Leionema can spread to about 4 ft (1.2 m) and reach about 3 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Two-lobed Leionema?
Prune Two-lobed Leionema while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.
How Do You Care for a Two-lobed Leionema in Winter?
Two-lobed Leionema is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.
How Do You Propagate a Two-lobed Leionema?
Two-lobed Leionema can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to ambiguous waxflower plant care, which shares the same genus.
Is the Two-lobed Leionema Toxic to Pets and Children?
Pet safety not verified
