This clear frosty weather is a great time for planning our summer garden. We’ve created these brand new dahlia collections that will grace your garden with their abundant blooms for months. They are also perfect to give as a gift. What could be more lovely than filling the corner of a friend’s garden with the colourful summer blooms of these pretty flowers? Enjoy!

Social media is awash with beautiful photos of dahlia bouquets. Get ahead of the trend and try our carefully selected blends of colours and flowering types. Our dahlia collections will flower from mid summer to autumn providing you with vase after vase of cut flowers. 

Dahlias are first and foremost garden plants that perform better in beds than pots. Use our collections to plan your summer flowering colour themes. Work with your existing perennials or choose from our colour selector to find harmonious bulbs to compliment your collection. 

How to plant dahlia collections

  • Choose a position in your garden that receives plenty of sun
  • Plant your dahlias 4-5 per square metre
  • Dig a hole 15cm deep to make room for the tuber but leave the stem exposed at the soil surface
  • Plant in the ground from April
  • Or pot up from March and place in a cold frame to protect from frost 


A collection will include a number of dahlias selected from our stock individually labelled so you have full control on how you want to plant your tubers. You can plant them in a dedicated cutting bed or spread them around your garden to make the most of their large foliage.
