Dwarf clarkia Plant Care

Dwarf clarkia (Clarkella nana) belongs to the Rubiaceae family within the Clarkella genus. Dwarf clarkia is native to India, China, Uttarakhand, the Western Himalayas, Burma and Thailand. Dwarf clarkia is also known as Miniature clarkia.

Dwarf clarkia displays a low rosette, clumping growth habit, reaching up to tall with a spread of approximately . Dwarf clarkia produces small, delicate white flowers in clusters.

Leaf size: approximately 1 inches.

Water a young or newly planted Dwarf clarkia every 3–7 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Dwarf clarkia thrives in bright indirect to partial shade. Avoid placing Dwarf clarkia in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Clarkella nana tolerates temperatures of 65–75°F. Dwarf clarkia prefers humidity levels of 40–60%.

Rich, well-draining soil with high organic content. Good drainage is essential for Dwarf clarkia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Dwarf clarkia every 2 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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 bright indirect to partial shade and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Prune Dwarf clarkia 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 tree in one year.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Dwarf clarkia can be propagated through seeds, division of offsets.

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