Million Bells are a tried and true annual for summer hanging baskets and container planters, but are sometimes passed over for the larger, flashier petunias. 'Superbells Double Twilight' calibrachoa should not be overlooked just because of its smaller size. Its double-petaled, two-toned lavender blooms are elegant and eye-catching, and a worthwhile addition to any sunny garden. Mounding up to 12 inches before spilling up to two feet over the edges of hanging baskets or container planters, this mini-petunia can also dress up sunny borders, but we think you'll appreciate the delicate looking flowers all the more when seen at eye level.
