Liriodendron tulipifera 'JFS-Oz'

Emerald City Tulip Tree

Liriodendron tulipifera ‘JFS-Oz’ (Emerald City® Tulip Tree) is a refined selection of tulip tree with a strong upright-oval, slightly compact habit, a dominant central leader, and deeper green, slightly glossy foliage than seed-grown trees. Like the species, it develops distinctive tulip-shaped greenish-yellow flowers with orange centers on mature trees, and its leaves turn a bright, clear yellow in fall. It is especially valued for its uniform growth, straighter form, and suitability as a street or shade tree.

Type: Tree (Deciduous)
Mature Size: 25' W × 55' H
USDA Zones: 4b–9b
Form: Upright oval, slightly compact

Light: Full sun
Soil / Water: Deep, moist, well-drained soils; moderate water, prefers consistent moisture once established
Bloom Time / Length: Late spring to early summer; short to moderate (about 2–3 weeks on mature trees)

Wildlife: Butterflies, hummingbirds

Features & Landscape Uses:
Excellent as a shade tree, street tree, or specimen for larger landscapes. Its more predictable shape, strong central leader, and relatively narrower canopy make it a more uniform landscape choice than typical seedling tulip trees. The dark green summer foliage and clear yellow fall color add strong seasonal interest.

Care:
Plant in full sun in deep, well-drained soil with room to mature. Water regularly during establishment and during dry spells. Minimal pruning is usually needed beyond structural shaping when young. Avoid compacted or persistently dry sites for best performance.
