Orange eye butterfly bush Plant Care

Orange eye butterfly bush (Buddleja myriantha) belongs to the Scrophulariaceae family within the Buddleja genus. Orange eye butterfly bush is native to upper Burma and western China, including Tibet. Orange eye butterfly bush is also known as Orange eye buddleia.

Orange eye butterfly bush displays a fast-growing shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Orange eye butterfly bush produces showy clusters of fragrant flowers in various colors.

Leaf size: approximately 6 inches.

Water a young or newly planted Orange eye butterfly bush every 7–10 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.

Orange eye butterfly bush thrives in full sun to partial shade.

Buddleja myriantha tolerates temperatures of 50–80°F. Orange eye butterfly bush prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Orange eye butterfly bush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Orange eye butterfly bush every 4 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Orange eye butterfly bush is suited to USDA Zone 8a – 9b.

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.

Orange eye butterfly bush can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Orange eye butterfly bush 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.

Orange eye butterfly bush is hardy down to USDA zone 8a, so once established it can stay outdoors through winter in that zone and warmer ones.

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.

Orange eye butterfly bush can be propagated through softwood cuttings, hardwood cuttings. Similar propagation techniques also apply to himalayan butterfly bush plant care, which shares the same genus.
