Ajuga macrosperma Plant Care

Ajuga macrosperma (Ajuga macrosperma) belongs to the Lamiaceae family within the Ajuga genus.

Ajuga macrosperma displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Ajuga macrosperma produces small, tubular flowers in shades of blue, purple, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Ajuga macrosperma 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.

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

Ajuga macrosperma tolerates temperatures of 50–75°F. Ajuga macrosperma prefers humidity levels of 40–60%.

Well-draining, fertile soil with a mix of organic matter like compost or peat moss. Good drainage is essential for Ajuga macrosperma to prevent waterlogging, which leads to root rot and fungal issues.

Feed Ajuga macrosperma 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 part shade to full shade and well-draining, fertile soil with a mix of organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Ajuga macrosperma 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.

Ajuga macrosperma 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 Ajuga macrosperma 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.

Ajuga macrosperma 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.

Ajuga macrosperma can be propagated through division, seeds.

Ajuga macrosperma is susceptible to aphids, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Ajuga macrosperma grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Ajuga macrosperma as a houseplant or bring it indoors before the first frost.
