Daylily 'Super Summer Mixed'


  • New in 2014
  • The spectacular Day Lily

The magnificent, showy trumpets of Daylily 'Super Summer Mixed' are carried on stiff stems above clumps of decorative, strappy foliage. The colourful lily-like blooms, each lasting only a day, are produced so freely that you will be able to spare a few stems for a short-lived arrangement of daylily flowers indoors. Daylilies are reliable hardy perennials, equally at home in cottage gardens or exotic borders where they are quick to establish and easy to maintain. Height and spread: 45cm (18").

Culinary note: Some parts of these flowers are edible. For more details about edible flowers click here.
