  Closely related to the ever-popular 'Caradonna', this new decorative sage shares similar characteristics to its cousin - apart from the unique colour of its flowers, which are a rich sky blue. They will mix really well with stronger purples, plums, most shades of pink and even silvers.
  
  
• Garden care: To prolong flowering remove the flower spikes as soon as they start to fade. Apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant in spring.
