Agapanthus Headbourne Hybrids

Agapanthus 'Headbourne Hybrids'

African Blue Lily

 Dark, steely-blue buds perched on firmly upright stems give way to striking lavender-blue, trumpet shaped blooms. Agapanthus ‘Headbourne Hybrids’ will flower freely from their second year, growing into dense, established clumps of strap-like, dark green foliage. In summer, this impressive perennial lends its stature to borders and patio containers, where their architectural seed heads continue the display well into autumn. The large spherical blooms are also magnificent in cut flower displays. Hardy in many parts of the UK, where good drainage and protective winter mulch is provided. Height: 90cm (36”). Spread: 45cm (18”). More info
