Canna 'Black Knight'

Canna are stunning, spreading, tall plants with bright coloured flowers on tall stems. Their exotic flowers appear from mid-summer and last to the first frosts. Theses are rhizomatous perennials, native to the Americas and are only half-hardy in the UK. They provide attractive specimens in mixed planting beds and are suitable for planting out in containers. ‘Black Knight’ boasts large lily-like flowers in crimson that contrast nicely with its burgundy tinted, green leaves. The blooms appear on strong upright stems that stand high above the foliage.

Planting in Spring

From Early Spring TO Mid Spring

In early Spring fill largish pots with compost to start them off, cover them with the compost but if there are any shoots leave them exposed. Water sparingly and leave in a warmish place. Harden them off by placing them in a greenhouse in mid spring before planting out after the risk of frost has passed. .
