Quick Guide
- Pure white flowers with pink eyes all summer
- Heat and drought tolerant tender annual
- Excellent for containers and hanging baskets
- Vigorous mounding habit, keeps flowering
- Deadhead spent blooms for continuous flowers
Pelargonium interspecific 'Calliope Medium White' is a vigorous tender annual with pure white semi-double flowers marked with delicate pink and red eyes. This award-winning cultivar from the Calliope® range is highly heat and drought tolerant, making it ideal for sunny UK summers. The plant develops into a compact, well-branched mound with semi-trailing habit, growing 30–40cm tall with a 40–50cm spread.
Plant in full sun in well-drained soil after the last frosts (late May). Water regularly but allow soil to dry slightly between waterings. Apply a balanced fertilizer every two weeks during the growing season. Deadhead spent flowers regularly to encourage continuous blooms throughout summer until the first hard frosts. This versatile cultivar excels in mixed containers, hanging baskets, window boxes, and summer bedding schemes.
Plant Guide
Plant after the last frosts in late May in a sunny location. Use well-draining potting compost or garden soil amended with organic matter. Water when the top feels dry but don't let it dry out completely. Feed fortnightly with balanced fertilizer once flowering begins. Deadhead regularly to extend the flowering season through autumn frosts. In very hot summers, afternoon shade may prevent scorching. This tender annual cannot survive UK winters; treat as annual and compost at season's end, or bring indoors to a frost-free location.
