Description
Calliope is an “interspecific hybrid” series, developed by crossing normal zonal (upright) geraniums with ivy geraniums. Well-grown Calliope baskets and containers have excellent sell-through at retail because of their controlled mounding habit, vibrant colors and superb outdoor performance. While the flowers are semi-double — similar to most other zonals — Calliope takes color to another level in geraniums. Calliope likes lots of sun and is both heat and drought tolerant. Geraniums don’t like “soggy feet,” so plant Calliope in well-draining soil and water when soil is dry to the touch. Feed twice a month with an all-purpose fertilizer and, for the best flower display, deadhead spent blooms as needed.
