 Dahlia 'Black Narcissus'

Plant details

Cactus and semi-cactus dahlias bear fully double flowers with pointed looking petals that curve in tightly for about half of their length.

Dahlia 'Black Narcissus' has dark maroon flowers with a pinkish centre. It's perfect for growing in a mixed herbaceous border, and makes an excellent cut flower.

For best results, grow Dahlia 'Black Narcissus' in full sun in fertile, well-drained soil. Deadhead regularly and feed with a potash-rich fertiliser to prolong flowering. Lift tubers after the first frosts and store them in a cool, dry situation until March. Then pot them up and keep them in a temperate greenhouse before planting out in late May.
