Bisse's calycogonium Plant Care

Bisse's calycogonium (Calycogonium bissei) belongs to the Melastomataceae family within the Calycogonium genus. Bisse's calycogonium is native to Brazil, Ecuador.

Bisse's calycogonium displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Bisse's calycogonium produces small, delicate pink or purple flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Bisse's calycogonium every 3–5 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.

Bisse's calycogonium thrives in partial shade to full shade. The optimal light range is 100–1,000 lux. Avoid placing Bisse's calycogonium in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Calycogonium bissei tolerates temperatures of 60–75°F. Bisse's calycogonium prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, acidic soil with high organic matter content. Good drainage is essential for Bisse's calycogonium to prevent waterlogging, which leads to root rot and fungal issues.

Feed Bisse's calycogonium 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 with high organic matter content. Avoid low spots where water collects after rain.

Bisse's calycogonium 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.

Bisse's calycogonium can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Bisse's calycogonium 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.

Bisse's calycogonium 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.

Bisse's calycogonium can be propagated through seeds, division of clumps.
