For many gardeners, summer annuals automatically means petunias, and with the range of colors, growth habits, and truly remarkable patterning, one can understand why. 'Purple Vein' petunia has a dark blue-purple center with dark veins radiating out across a pale, pale petal. More of a mounding habit than a trailer, it fills container planters nicely while imparting a touch of elegance. When given ample sun, regular water, and consistent fertilizing, 'Purple Vein' petunia will maintain its good looks right up until freeze.
