Velvety Viola

Also known as a pansiola, Anytime® Viola 'Sugarplum' is a charmer. The trailing plants keep blooming in warm weather, after most violas stop, and add winter color to hardiness zones 5 to 10. Let them spill over the sides of containers, or mass them in the landscape for deep burgundy-purple color with hints of white, gold and lavender. For a long-lasting display, spend a few minutes every day or two dead-heading fading flowers.
