Bearded irises

We are thoroughly enjoying the flowering of our stock plants of bearded irises – such a range of colours and forms with the benefit of scent. You may have missed the boat for this year’s flowering, but there is plenty of time to grow some for next year! We will have a complete set of images should you need them. Is there a group of plants that have the full range of colour including the three pure primary colours? Irises don’t do pure red: roses, dahlias and tulips don’t do pure blue (despite claims to the contrary), penstemons don’t do yellow. No prize offered but correspondence welcome.
