Canna Lilies are exotic tropicals that thrive in the hot summer months. Their flowers come in many bright, flashy colours – red, orange, yellow & pink. Most foliage comes in green, but there are many colours depending on the variety from variegated, bronze & maroon. Their leaves are wide and long, similar to banana leaves. Canna Liles have a wax coating to protect against fungal diseases. Dwarf Canna Lilies have a more compact growth habit and can grow up to 4-6 feet tall. In cold climates, Cannas are considered annuals that flower from spring until frost.
