We have 3 varieties of cannas which have grown too big for their boots, so are being split. one is Ambassadour, one Apache. colours are red, salmon and yellow,…
They are frost tender, min 10-15C and will require a warm, sunny position and humus-rich moist soil. If grown under glass or for summer bedding, encourage into growth in spring at 16C and store rhizomes in slightly damp soil or peat in winter.
You can propagate in the spring or by division in the winter or by seed. They need a minimum of 20C to germinate.
