Aphanocarpus steyermarkii Plant Care

Aphanocarpus steyermarkii (Aphanocarpus steyermarkii) belongs to the Rubiaceae family within the Aphanocarpus genus.

Aphanocarpus steyermarkii displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Aphanocarpus steyermarkii produces small, white, star-shaped flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Aphanocarpus steyermarkii every 5–7 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.

Aphanocarpus steyermarkii thrives in partial shade to full shade. The optimal light range is 100–500 lux. Avoid placing Aphanocarpus steyermarkii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Aphanocarpus steyermarkii tolerates temperatures of 60–75°F. Aphanocarpus steyermarkii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, acidic soil mix with high organic content. Good drainage is essential for Aphanocarpus steyermarkii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Aphanocarpus steyermarkii 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.

Choose a spot with partial shade to full shade and well-draining, acidic soil mix with high organic content. Avoid low spots where water collects after rain.

Aphanocarpus steyermarkii 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.

Aphanocarpus steyermarkii 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.

Prune Aphanocarpus steyermarkii 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.

Aphanocarpus steyermarkii 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.

Aphanocarpus steyermarkii can be propagated through seeds, division of rhizomes.

Aphanocarpus steyermarkii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Aphanocarpus steyermarkii as a houseplant or bring it indoors before the first frost.
