Use: Accent standard used in a group or medium height flowering tree. This is a magnificent small subtropical tree that stands out when in bloom.
Characteristics: Tibouchina granulosa blooms off and on throughout the year. The beautiful deep purple flowers are striking in any landscape. Trees are often installed quite small, around 6-7' tall and used in groupings. They can, however stand-alone, and grow to 20'.
Trimming: Tip back Tibouchina in the spring as temperatures start to rise. Immediately follow trimming with fertilizer application. Tip back again after spring (summer) flowers have expired. This will keep foliage full throughout. Again, follow trim with fertilizer application.
Fertilization: Apply well balanced, time-released granular fertilizer with minor elements in March, and October to coincide with tipping back. Apply a granular, bloom special blend in June to encourage fall flowering. Do not skip fertilizations, as plants will quickly become chlorotic/yellow.
