Dahlia and cosmos pot display

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: 1 hour

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.
