Scalesia affinis Plant Care

Scalesia affinis (Scalesia affinis) belongs to the Asteraceae family within the Scalesia genus. Scalesia affinis is native to the Galápagos Islands, Ecuador.

Scalesia affinis displays a tall, upright shrub growth habit, reaching up to 6 ft tall with a spread of approximately 3 ft. Scalesia affinis produces small, daisy-like flowers in various colors.

Leaf size: approximately 4 inches.

Water a young or newly planted Scalesia affinis 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.

Scalesia affinis thrives in full sun to partial shade.

Scalesia affinis tolerates temperatures of 60–80°F. Scalesia affinis prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added organic matter. Good drainage is essential for Scalesia affinis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Scalesia affinis every 6 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, fertile soil with added organic matter. Avoid low spots where water collects after rain.

Scalesia affinis is suited to USDA Zone 13a.

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.

Scalesia affinis can spread to about 3 ft (0.9 m) and reach about 6 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Scalesia affinis 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.

Scalesia affinis 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.

Scalesia affinis can be propagated through seeds. Similar propagation techniques also apply to baur's scalesia plant care, which shares the same genus.

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

Scalesia affinis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Scalesia affinis is native to the Galápagos Islands, Ecuador. In cooler regions, grow Scalesia affinis as a houseplant or bring it indoors before the first frost.
