1 Geranium Calliope M Red Splash, Hardy Outdoor Summer Flowering Patio Plant, 5 Litre Root-Ball

Geranium Calliope M Red Splash

The Geranium Calliope M Red Splash is a stunning interspecific hybrid pelargonium, bred by crossing zonal and ivy-leaved types to deliver exceptional vigour, outstanding weather tolerance and a longer flowering season. Part of the acclaimed Calliope M (medium) series, this variety produces eye-catching semi-double blooms in rich red tones with distinctive lighter splashes, creating a striking bicolour display throughout the summer months and well into autumn.

Calliope geraniums are renowned for their superior garden performance compared to traditional pelargoniums. Their robust, semi-trailing to mounding habit makes them ideal for patio containers, window boxes, hanging baskets and border planting. The dark-zoned, rounded foliage provides an attractive backdrop to the vibrant flower heads, and the plants remain compact and well-branched without excessive leggy growth.

Supplied as a well-established plant in a 5 litre root-ball, ready for immediate planting or display in your chosen container.
