What Is the Gnephosis trifida?
Gnephosis trifida (Gnephosis trifida) belongs to the Asteraceae family within the Gnephosis genus. Gnephosis trifida is native to the south-west of Western Australia.
Gnephosis trifida displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Gnephosis trifida produces small daisy-like flowers in shades of white, pink, or purple.
Leaf size: approximately 2 inches.
How Often Should You Water a Gnephosis trifida?
Water a young or newly planted Gnephosis trifida every 7–10 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 Gnephosis trifida?
Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Gnephosis trifida to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Gnephosis trifida?
Feed Gnephosis trifida 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 Gnephosis trifida?
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.
Gnephosis trifida is suited to USDA Zone 13a.
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 Gnephosis trifida?
Gnephosis trifida can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 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 Gnephosis trifida?
Prune Gnephosis trifida 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 Gnephosis trifida in Winter?
Gnephosis trifida is frost-tender (hardy to USDA zone 13). 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 Gnephosis trifida?
Gnephosis trifida can be propagated through seeds, division of clumps. Similar propagation techniques also apply to needle-leaf gnephosis plant care, which shares the same genus.
Is the Gnephosis trifida Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Gnephosis trifida, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What USDA Hardiness Zone Does the Gnephosis trifida Need?
Gnephosis trifida grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Gnephosis trifida is native to the south-west of Western Australia. In cooler regions, grow Gnephosis trifida as a houseplant or bring it indoors before the first frost.
