Boston Ivy

Boston Ivy (Parthenocissus tricuspidata)

Boston Ivy is a fast-growing, deciduous climber valued for three-lobed leaves that transform from glossy green to fiery red and purple in fall; self-clinging tendrils with adhesive pads allow it to cloak masonry walls, fences, and arbors for dramatic seasonal impact.

Distinctive Features

Handsome, lobed foliage provides dense coverage and brilliant fall color, while disk-tipped tendrils adhere to most masonry surfaces and small clusters of inconspicuous flowers give way to blue-black berries for wildlife interest.

Growing Conditions

• Sun Exposure: Full sun to partial shade; brightest fall color in more sun.
• Soil: Well-drained loam enriched with organic matter; adaptable to a range of soils.
• Water: Moderate; keep evenly moist during establishment, then water in prolonged dry spells.
• USDA Hardiness Zones: 4 to 8.
• Mature Size: 30 to 50 ft with support; spreads widely by tendrils.
• Bloom Time: Late spring to early summer; flowers are discreet.
• Soil pH: Slightly acidic to neutral, about 6.0 to 7.5.

Ideal Uses

• Focal Point: Vivid fall foliage creates a striking architectural veil.
• Wall Greening: Covers brick, stone, and concrete quickly.
• Pergolas/Arbors: Trains readily on sturdy structures.
• Screening: Provides seasonal privacy on fences and walls.
• Erosion Control: Can sprawl as a groundcover on sunny slopes.

Low Maintenance Care

• Watering: Deeply water new plantings; reduce frequency once established.
• Pruning: Trim after leaf-drop or in late winter to control size and keep windows and gutters clear.
• Fertilizing: Top-dress with compost in spring; use balanced slow-release fertilizer if growth is weak.
• Mulching: 2 to 3 in organic mulch to conserve moisture and suppress weeds.
• Notes: Adhesive pads can mark painted wood and stucco; best on durable masonry. Monitor spread and keep off trees and siding.
