Green Vase Japanese Zelkova

Green Vase Japanese Zelkova (Zelkova serrata 'Green Vase')

Green Vase Japanese Zelkova is a dependable shade tree that brings a classic, upright silhouette to streetscapes and large landscapes without feeling bulky. It develops a graceful canopy that provides comfortable summer shade while keeping sightlines and pathways more open than many broad-crowned trees. The clean, green foliage holds up well through the growing season, then finishes the year with warm fall color. If you want a tough, city-friendly tree that still looks refined in a residential setting, this cultivar is a strong fit.

Distinctive Features

This tree is known for its vase-shaped habit with upright, arching branches that echo the look of an elm while avoiding major elm disease concerns. Leaves are medium to dark green through summer and typically shift to orange and bronze-red tones in fall, with color intensity varying by site and season. Bark becomes more interesting with age, developing exfoliating patches that reveal lighter tones beneath. Small spring flowers are not showy, followed by small, dry, winged fruits that are not messy in most settings.

Growing Conditions

• Sun: Full sun is best, with tolerance for part shade.
• Soil: Adaptable to many soils, but perform best in well-drained loam and avoid persistently wet sites.
• Water: Medium moisture, keep evenly moist while establishing, then moderate drought tolerance once established.
• USDA Zones: Zones 5 to 8.
• Mature Size: Typically 60 to 80 feet tall and 40 to 50 feet wide.
• Habit: Upright, vase-shaped canopy with ascending, arching branches.
• Notable Traits: Heat tolerant and urban tolerant, with good performance along streets and in tougher sites.

Ideal Uses

• Focal Point: Use it as a focal point in a large lawn or open bed where its vase-shaped canopy can define the space with long-term structure.
• Street Tree: Plant along streets and driveways for dependable shade and a clean, upright form that fits tighter corridors.
• Shade Canopy: Use to cool patios, play areas, and outdoor seating with broad, dappled summer shade.
• Parkway Planting: Choose for urban and suburban parkways where toughness and a refined silhouette both matter.
• Property Screening: Use as a high canopy layer to add separation and privacy without forming a solid wall at eye level.

Low Maintenance Care

• Pruning: Prune in late winter to early spring to develop strong structure and maintain clear trunks and branch spacing.
• Watering: Water deeply during the first one to two growing seasons, then irrigate during prolonged drought for best growth and fall color.
• Mulching: Mulch over the root zone to conserve moisture and reduce competition, keeping mulch a few inches away from the trunk.
• Soil Drainage: Improve drainage in heavy soils and avoid low, wet sites to reduce stress and decline.
• Staking: Stake only if needed in windy sites, and remove supports after the first season to encourage stronger trunks.
