Calliope Dark Red is one of a new generation of interspecific hybrid geraniums. These are crosses between ivy geraniums and traditional upright (zonal) geraniums. As is often the case with hybrids, the result is a plant bearing the best characteristics of both parents along with increased vigor. Calliope has a semi-trailing habit, making it suitable for both pots and hangers. The flowers are huge, with vibrant colors set against lush, deep green foliage. Calliope tolerates heat better than most other annuals.
Deadheading is not strictly necessary, but helps to keep the plant looking tidy. Keep in full sun (minimum of half a day). Keep moist but not soggy. Feed regularly with a liquid or slow release fertilizer.
