Plant of the week –
Common Name: variegated canna ‘pretoria’, canna lily
Botanical Name: canna x generalis
Pretoria is perhaps the showiest of all of the variegated cannas and one of the best for hot, humid, sunny southern gardens. Favored for its bright green and yellow variegated foliage and deep tangerine flowers, Pretoria will grow at the edge of ponds in shallow water as well as in normal garden conditions.
Cannas grow from rhizomes. They are easy to plant and easy to grow. Their flowers come in a wide variety of colors including red, orange, yellow, pink and fuchsia. They have long, heliconia or banana-like leaves giving them a very tropical look. Cannas should be treated like other tropical plants; plant in spring after chance of last frost and dig before first hard freeze in fall. The rhizomes can be stored over winter in a cool dry place in colder climates.
