The Story

Plant Bio

Liriodendron tulipifera, or tulip tree, is a large, fast-growing deciduous tree native to eastern North America, known for its unique tulip-shaped flowers and lobed leaves. Emerald City® ('JFS-Oz') is distinguished by its uniform, upright pyramidal to oval habit, deeper green glossy foliage, and more consistent, clear yellow fall color than the species.

Bloom Period:

EarlyLate

Uses & Benefits:

A magnificent large tree prized for its unique flowers, distinctive leaf shape, and stately form. The 'Emerald City' cultivar offers a more refined habit and reliable, beautiful yellow fall color, making it an excellent specimen tree.

Its dense canopy provides excellent shade, helping to cool homes and outdoor living spaces in summer. The strong, straight trunk made it a historically important timber tree for Native Americans and early settlers.

The flowers are a significant nectar source for bees and other pollinators. The tree hosts the larvae of the eastern tiger swallowtail butterfly, and its seeds provide food for birds and small mammals.

Planting

How to Grow

Choose a location with full sun and deep, moist, well-drained soil.
Dig a hole two to three times wider than the root ball.
Place the tree in the hole, ensuring the root flare is at ground level.
Backfill with the original soil, gently firming it around the roots.
Water thoroughly after planting to settle the soil.
Apply a 2-3 inch layer of mulch, keeping it away from the trunk.

Pro Tip

Provide consistent moisture during the first few years to prevent leaf yellowing and drop during dry spells.

Keep It Thriving

Care Guide

Do

Water deeply and regularly, especially during establishment and drought.
Maintain a large, mulch-covered root zone to protect shallow roots.
Prune for a single central leader when young to ensure good structure.

Don't

Don't plant in dry, compacted, or alkaline soils.
Avoid planting near sidewalks or driveways where roots can cause damage.
Don't over-fertilize, as this can lead to weak, rapid growth.
