Petunias have wide trumpet-shaped flowers and branching foliage that is hairy and somewhat sticky. Within the petunia family, there is great variety: single and double blooms, ruffled or smooth petals, striped, veined or solid colors, mounding and cascading habits and even some with fragrance. Most of the petunias sold today are hybrids, developed for specific design purposes. They grow easily when you transplant them to the garden, and this should be done in the spring when the threat of frost has passed.
