Australian plants are like the ultimate self-sacrificing mother: They give and give (certain trees can reach 20 feet in just a few years and flower for six weeks or more) but ask so little in return. (Fertilizer? Rain? If you insist.) Their fantastical forms, however—including sculptural, hairy, or waxy blooms in neon colors—are anything but matronly.
A bit quirky but totally cute, the ruffled, often semidouble flowers of Viola Angel Amber Kiss are very un-viola-like. Ruddy orange with a yellow center and rose-colored reverse on the wings. Each flower seems to have its own personality. Plants are 6 to 8 inches across; flowers are about an inch wide.
