Dierama Collection

Often referred to as Angel's Fishing Rod, it looks particularly attractive when overhanging water. Height: 100cm (39"). Spread: 45cm (18").

  • Dierama argyruem - Dazzling white bell shaped flowers that dangle from arching stems.
  • Dierama 'Blackberry Bells' - Deep purple pink blooms on wiry stems.
