Arnold Tuliptree has chartreuse cup-shaped flowers with gold eyes held atop the branches from mid to late spring. It has emerald green foliage throughout the season. The square leaves turn an outstanding gold in the fall. The fruit is not ornamentally significant. The furrowed gray bark is extremely showy and adds significant winter interest.

Planting & Growing
Arnold Tuliptree will grow to be about 60 feet tall at maturity, with a spread of 10 feet. It has a high canopy with a typical clearance of 5 feet from the ground, and should not be planted underneath power lines. It grows at a fast rate, and under ideal conditions can be expected to live to a ripe old age of 100 years or more; think of this as a heritage tree for future generations!
This tree should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil pH, but grows best in rich soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided. This is a selection of a native North American species.
