Overview

Wheeler's Dwarf Pittosporum (Pittosporum tobira 'Wheeleri') is a non-native shrub suited to Tampa landscapes.

Mature Size and Habit

Expect about 3 to 4 feet tall and 4 to 5 feet wide, forming a low, rounded evergreen mound of thick, glossy, dark green leaves. Growth is slow.

Best Landscape Uses

Use it for low foundations, broad borders, clipped or informal low hedges, mass plantings, and substantial containers. Respect its mature width so foliage does not cover walks, vents, or irrigation heads.

Sunlight

Full sun to partial sun is suitable. Afternoon shade reduces heat load beside west-facing pavement, while heavy shade produces a loose canopy and slower drying after rain.

Soil, Drainage, and Irrigation

This pittosporum adapts to sandy and moderately alkaline Florida soils when drainage is good. Water regularly during establishment, then allow the upper soil to dry between deep irrigations; saturated roots invite decline.

Best Planting Season for Tampa and Central Florida

October through early spring offers easy establishment. Summer planting requires reliable drainage and frequent root-ball checks.

Pruning and Maintenance

Its naturally compact habit needs only selective shaping and removal of dead wood. Monitor scale, aphids, leaf spots, and root rot, and avoid repeated hard shearing that traps dead material inside the mound.

Wildlife Value

Flowers are small and wildlife value is limited compared with native berry or nectar shrubs. Combine it with Florida-native flowering plants if pollinator and bird support are major design goals.

Cold and Heat Sensitivity

Wheeler's dwarf pittosporum is hardy through Tampa's normal winters and tolerates heat, wind, and coastal exposure once established. New growth can burn in an unusual hard freeze but usually recovers from healthy wood.

Safety, Roots, and Placement Warnings

The shrub has no major thorn or aggressive-root issue. Its dense low form can hide irrigation leaks, litter, or pests, so retain inspection access around walls, utilities, and equipment.

Invasive Concerns

Pittosporum tobira is non-native, but UF/IFAS currently classifies it as not a problem species throughout Florida. Keep the cultivar within maintained beds and remove any volunteer seedlings.
