Dahlia and cosmos pot display

Dahlias come in a fascinating variety of shapes and sizes, and the pom-pom types, with their rows of incurved petals, resemble old-fashioned bathing caps. Dahlia ‘Franz Kafka’ lends itself – ironically, given its name – to a relaxed cottage-garden style, floating like balloons above the feathery foliage of Cosmos ‘Sensation’ and its delicate, pink petals.

Use a large container for this display, as this combination of plants reaches 1m in height. Prevent the planting scheme from looking too top heavy with a skirt of cerinthe. Its silvery blue leaves lift the dusky pink and purple flowers beautifully.
