Sphaereupatorium scandens Plant Care

Sphaereupatorium scandens (Sphaereupatorium scandens) belongs to the Asteraceae family within the Sphaereupatorium genus.

Sphaereupatorium scandens displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Sphaereupatorium scandens produces small white clustered flowers in terminal corymbs.

Leaf size: approximately 4 inches.

Water a young or newly planted Sphaereupatorium scandens 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.

Sphaereupatorium scandens thrives in full sun to partial shade.

Sphaereupatorium scandens tolerates temperatures of 65–80°F. Sphaereupatorium scandens prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Sphaereupatorium scandens to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sphaereupatorium scandens 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 full sun to partial shade and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Sphaereupatorium scandens is suited to USDA Zone 13b.

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.

Sphaereupatorium scandens can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Sphaereupatorium scandens 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.

Sphaereupatorium scandens 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.

Sphaereupatorium scandens can be propagated through seeds, division of root ball.

Sphaereupatorium scandens 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.

Sphaereupatorium scandens grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. In cooler regions, grow Sphaereupatorium scandens as a houseplant or bring it indoors before the first frost.
