Description
Geranium Calliope M Scarlet Red – Large Flowering Summer Bedding Plant
The Geranium Calliope M Scarlet Red is a stunning interspecific hybrid pelargonium from the award-winning Calliope series by Syngenta. A cross between zonal and ivy-leaf geraniums, this variety combines the best traits of both parents — producing large, semi-double blooms in a vivid scarlet red, set against rich, dark-green foliage with subtle zonal markings. Renowned for outstanding heat tolerance and continuous flowering, Calliope Scarlet Red delivers bold, long-lasting colour from late spring right through to the first frosts of autumn.
This plant is supplied as a well-established, garden-ready specimen in a 5 Litre root-ball, giving you a head start on a spectacular summer display. Its vigorous, semi-trailing to mounding growth habit makes it equally suited to large patio containers, window boxes, hanging baskets, and sunny border positions.
Key Features:
- Large, semi-double scarlet red flowers with excellent colour intensity
- Interspecific hybrid — exceptional vigour and weather resilience
- Continuous blooming from late spring through to autumn
- Strong heat and drought tolerance once established
- Semi-trailing to mounding habit — ideal for containers and borders
- Dark green foliage with attractive zonal markings
- Supplied as a well-established, garden-ready 5 Litre root-ball plant
Planting and Care:
Plant in a sunny, sheltered position for the best flowering performance. Geranium Calliope thrives in well-drained, fertile compost or soil. Water regularly, allowing the growing medium to dry slightly between waterings — avoid waterlogging. Deadhead spent blooms regularly to encourage continuous flowering throughout the season. Feed fortnightly with a high-potash liquid fertiliser during the flowering period. Although tolerant of heat and periods of dry weather, consistent care will reward you with the most prolific display. As a tender perennial, this plant is not frost hardy and should be overwintered indoors in a cool, bright, frost-free location if you wish to keep it for the following year.
