Siphocampylus asplundii Plant Care

Siphocampylus asplundii (Siphocampylus asplundii) belongs to the Campanulaceae family within the Siphocampylus genus. Siphocampylus asplundii is native to Ecuador.

Siphocampylus asplundii displays an upright, branching shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Siphocampylus asplundii produces tubular flowers in shades of blue, purple, or pink.

Leaf size: approximately 4 inches.

Water a young or newly planted Siphocampylus asplundii 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.

Siphocampylus asplundii thrives in bright indirect light. Avoid placing Siphocampylus asplundii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Siphocampylus asplundii tolerates temperatures of 60–75°F. Siphocampylus asplundii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added perlite for improved drainage. Good drainage is essential for Siphocampylus asplundii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Siphocampylus asplundii 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light and well-draining, fertile soil with added perlite for improved drainage. Avoid low spots where water collects after rain.

Siphocampylus asplundii is suited to USDA Zone 13a.

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.

Siphocampylus asplundii 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 Siphocampylus asplundii 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.

Siphocampylus asplundii 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.

Siphocampylus asplundii can be propagated through seeds, division of clumps. Similar propagation techniques also apply to siphocampylus affinis plant care, which shares the same genus.

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

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