Canna x generalis
Canna lilies feature vibrant coloured flowers on stems of large tropical leaves. Their foliage can be bright green, purple-red or even variegated. They are long flowering and low maintenance.
Forming dense clumps, Canna's happily grow in areas of poor drainage though they do require a sunny position in the garden.
Being perennial, Canna's die back in Winter and their stems can be cut to the ground. They will return each Spring.
