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

Water a young or newly planted Buddleja pichinchensis 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.

Buddleja pichinchensis thrives in full sun to partial shade.

Buddleja pichinchensis tolerates temperatures of 50–80°F. Buddleja pichinchensis prefers humidity levels of 40–70%.

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

Feed Buddleja pichinchensis 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.

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.

Buddleja pichinchensis 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 Buddleja pichinchensis 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.
