Tibouchina urvilleana (tib-oo-KYE-nuh er-vill-ee-AY-nuh) is native to Brazil and is commonly known as princess flower, glory bush, and purple glory bush. The princess flower is a versatile flowering evergreen shrub that can add interest to any landscape. It is ideal for a mixed border that includes shrubs and perennials, and it also works well in groupings of shrubs. Depending
on how it is trained, this plant can demonstrate either a mounding shrub or small tree form. When mature, T. urvilleana reaches 10 to 15 feet high and 10 to 12 feet wide. It is fast growing and can be propagated by softwood cuttings and division of clumps.
The princess flower produces brilliant royal-purple flowers from May
to January. The 3-inch diameter flowers have a fluorescent quality that
is complemented by very attractive foliage. The large coarse leaves are
2 to 4 inches long and 1 to 11/2 inches wide, with three to five major veins along the length of each leaf.
One of T. urvilleana’s unique qualities is that it can display vivid flowering
for several months of the year when provided full sun, well-drained soil and regular watering. Another unique quality is its high drought tolerance. Its ability to survive periods of drought, however, comes at the expense of flower production. This shrub is most popular in frost-free areas of the world but will perform well in USDA hardiness zones 8 through 12. In zones that experience seasonal freezing temperatures, the princess flower will die back after a hard frost but return to bloom again in mid- to late-summer.
The princess flower could easily become your favorite flowering shrub. An ideal place to use this regal shrub would be near an outdoor living area where the flowers and foliage can easily be seen. Princess flower adds texture and interest to foundation and border plantings with enough color to grab the attention of anyone who passes by. As the popularity of this shrub increases, you may see other
Tibouchina species make their way to your local nursery.
