Ornamental Features

The pointy leaves turn an outstanding red in the fall. The mottled khaki (brownish-green) bark is extremely showy and adds significant winter interest.

Landscape Attributes

Skyrocket Hybrid Stewartia is a dense multi-stemmed deciduous tree with a distinctive and refined pyramidal form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

This is a relatively low maintenance tree, and should only be pruned after flowering to avoid removing any of the current season's flowers. It has no significant negative characteristics.

Skyrocket Hybrid Stewartia is recommended for the following landscape applications;

  • Accent
  • Shade

Planting & Growing

Skyrocket Hybrid Stewartia will grow to be about 25 feet tall at maturity, with a spread of 15 feet. It has a low canopy with a typical clearance of 3 feet from the ground, and should not be planted underneath power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 70 years or more.

This tree does best in full sun to partial shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is very fussy about its soil conditions and must have rich, acidic soils to ensure success, and is subject to chlorosis (yellowing) of the foliage in alkaline soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.

This plant is not reliably hardy in our region, and certain restrictions may apply; contact the store for more information.
