Rain really beats down pansy flowers, but violas bounce back quickly.
Violas are smaller than pansies (between the size of a nickle and a quarter) but have more flowers per plant. They come in blue, yellow, white, and cream and bi-colored varieties. ('Penny Mickey' is pictured here.)
Use violas for mass color in borders and edging, as covers for spring bulbs, or for quick color in winter containers.
Violas take sun or part shade. Pick flowers to prolong bloom. Remove plants in summer if they begin to look ragged.
