Landscape Attributes

Princess Flower is an open multi-stemmed evergreen shrub with an upright spreading habit of growth. 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 shrub will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting butterflies to your yard. It has no significant negative characteristics.

Princess Flower is recommended for the following landscape applications;

  • Mass Planting
  • Hedges/Screening
  • General Garden Use
  • Container Planting

Planting & Growing

Princess Flower will grow to be about 15 feet tall at maturity, with a spread of 15 feet. It has a low canopy with a typical clearance of 2 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more.

This shrub does best in full sun to partial shade. 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 somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This species is not originally from North America.

Princess Flower makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Its large size and upright habit of growth lend it for use as a solitary accent, or in a composition surrounded by smaller plants around the base and those that spill over the edges. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, this plant may be too tender to survive the winter if left outdoors in a container. Contact our store for more information on how to protect it over the winter months.

This plant is NOT RELIABLY WINTER HARDY and considered "TROPICAL" in our region. It must be over-wintered inside with supplemental heat or used as a 1-season annual plant. The plant's desirable characteristics make it a good choice for growing in patio containers or flower gardens. Contact the store for care and over-wintering information.
