Pollypetite Althea Tree Form

Pollypetite Althea Tree Form brings softness and structure in one charming package. This dwarf tree-form Althea is neatly rounded and stays compact, growing just 8 feet tall and 5 feet wide - perfect for smaller landscapes, patios, or container plantings. Its soft lavender blooms appear from spring through summer, each one adding a calming pop of color against dark green foliage.

• Deciduous tree
• Moderate growth rate
• Lavender blooms from spring into summer
• Dense, rounded form ideal for tight spaces
• Pollinator friendly

Plant in full sun and well-drained soil. Hardy in USDA zones 5-9. Whether placed along a path, in a courtyard, or as a gentle focal point, Pollypetite offers long-lasting color in a refined, easy-to-manage shape that is known for being nearly seedless. It thrives in heat, handles drought once established, and brings subtle beauty to spaces that need a touch of color without overwhelming the design.

Pollypetite Althea Tree Form becomes especially low-maintenance once established. Its restrained growth and defined canopy keep care structured and manageable year after year. This is all it needs to thrive:

• Watering: Water deeply during the first growing season to establish a stable, well-anchored root system. After establishment, it tolerates moderate dry conditions but benefits from occasional deep watering during extended heat to maintain consistent foliage and bloom performance.
• Pruning: Prune in late winter or early spring before new growth begins. Remove any shoots along the trunk and lightly thin interior canopy growth to preserve airflow and maintain a balanced crown, since flowering occurs on new wood.
• Fertilizing: Apply a balanced, slow-release fertilizer in early spring as buds begin to swell. Avoid high-nitrogen feeding, which can encourage dense foliage growth that reduces overall bloom visibility.
• Mulching: Maintain a 2-3 inch layer of mulch around the root zone to conserve moisture and stabilize soil temperatures. Keep mulch several inches away from the trunk to prevent excess moisture against the bark.
• Winter Care: Established specimens are reliably hardy and rarely require special winter protection. Young tree-form trunks may benefit from temporary wrapping during their first few winters in colder climates to prevent bark stress.

Pollypetite Althea Tree Form is generally resilient, though compact growth can occasionally create minor airflow concerns. Early monitoring keeps most issues simple to manage.

• Aphids: Tender shoots may curl slightly and develop sticky residue from feeding insects. A firm rinse with water or insecticidal soap typically controls populations quickly.
• Powdery Mildew: Dense canopy growth may allow a white powdery film to develop in humid conditions. Light thinning improves airflow and significantly reduces recurrence.
• Leaf Spot: Small brown lesions may appear during prolonged wet weather. Removing affected foliage and maintaining spacing helps limit spread.
• Root Stress from Overwatering: Yellowing leaves and slowed growth may indicate saturated soil. Improving drainage and reducing irrigation frequency restores balance.
• Minor Trunk Sunscald: Young trunks may develop vertical cracking after sudden winter temperature shifts. Protective trunk wraps during early years reduce risk.
