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.
You Will Need
- Dahlia 'Franz Kafka' (3)
- Cosmos 'Sonata Carmine' (2)
- Cosmos 'Sensation' (2)
- Cerinthe major 'Purpurascens' (3)
- Multi-purpose, peat-free compost
- Old tin bath or bucket
Total time:
Step 1

If you’re using a metal container, line the sides with cardboard to prevent it from heating up and drying out the compost.
Step 2

Half-fill with multi-purpose compost and add gravel for drainage.
Step 3

Plant up the centre of the container with dahlias and cosmos, and the front and sides with cerinthe.
Step 4

Backfill with compost, and firm gently to remove air pockets. Water well and place in a sunny location.
Kevin Smith says…
Reclaimed containers are great for creating a rustic look full of cottage-garden charm. Tin baths and buckets are perfect for the job – just be sure to drill drainage holes in the base before planting.
