A photo I took at the Dallas Arboretum
These eight 3-gal plants were installed three months ago. They've almost got the tibouchina surrounded!
Fairly new plantings. Taken June 23, 2006
Cuphea hyssopifolia Humb., Bonpl. & Kunth
Annual only and not very drought resistant, but fast growing and really fills in bare spots in a garden or pot.
