    Standing proud amongst a densely planted herbaceous border, the glowing white flowerspikes add vertical interest with their distinctly upright habit. The 'Guardian' delphiniums are fast becoming the growers favourite, as they are known to produce a uniform display earlier in the year than many other types.

  • Garden care: Protect young foliage against slug and snail damage in spring. Stake with bamboo canes in mid-spring, before the flowers appear. During the growing season, apply a balanced liquid fertiliser every 2-3 weeks and wearing gloves cut back the faded flower-stems to a flowering side-shoot to encourage repeat flowering. At the end of autumn cut back and compost the faded flower-stems.

      These are plug plants, so ideally they should be grown on for their first year, and would usually go on to produce flowers in their second year.
