Canna lilies are some of the most colourful tropical-looking summer bulbs with high visual impact, so plant them for maximum effect! Perfect for the garden or for container growing. They have ruffled spikes that taper to refined buds, and in the case of Electric Lemonade, open to reveal soft yellow blooms with orange speckles in the centre. If your gardening season is short, start plants indoors, then plant out when you plant your tomato plants. They need lots of sunshine, fertile, moist soil and a good supply of water. Stake when necessary, and deadhead when blooms fade in order to promote continued flowering.
