Answer: Convolvulus is a vining, twiny plant, rather than a trailing plant. It won't cascade down as it grows, but will insist upon climbing up the supports of your hanging baskets. You might try some of the succulents, like 'Donkey's Tail, for your sunny, dry hanging planter, or Kennilworth Ivy, Creeping Charlie or Creeping Phlox. None of these plants will provide the large trumpet-shaped blooms of Convolvulus, but they will each be attractive in their own way, will thrive in full sunshine and dry soil, and will cascade over the sides of your hanging baskets.
