While there's certainly nothing wrong with that (after all, who doesn't love a beautiful rose in their garden), there are more varieties on offer if you want to try something new for your flowerbed ideas this summer. 

To get you inspired to step outside of your comfort zone, we've chosen five unusual and often overlooked blooms that are guaranteed to give your garden a talking point this summer. Which ones will you add to your planting list...

This unusual perennial has nectar rich flowers that butterflies love – hence its name. Golden-orange in color, they are a great choice for sunny borders and are showy in style. They will flower from July to September so they’re a good option for late color. 

Ideal for wildlife gardens, when autumn approaches the flowers turn into long seed heads that split open to reveal seeds adorned with strands of silken white hairs.
