Cannas are lovely ornamental garden plants with huge leaves and vibrant blossoms on tall stalks. They are best for borders and garden beds because of their vibrant mixture of colors and attractive foliage. Cannas are also excellent as potted plants, adding color to the patios.
Their leaves are broad, flat, typically solid green or brownish or maroon or even variegated. Flowers are typically red, orange or yellow or any combination of those colors. Cannas make a very attractive planting for a large container, in raised beds or as background plants.
Cannas should be planted in well drained, rich organic soil. They love hot humid weather. Canna lilies prefer full sun but can survive in partial shade. They need moisture to keep blooming. They are remarkably disease free.
How to grow Canna Lilies:
Cannas are propagated by rhizomes or seed.
1) To plant Cannas, loosen the soil to a depth of 12-15 inches, then mix in a 2-4 inch layer of compost. Dig a hole of 2-3 inches deep and set the rhizome in the hole, eyes up. Cover with soil and tramp firmly. Water thoroughly. Space rhizomes 1-4 feet apart.
2) The germination rate of the seed is very low and they need to be filed or given an acid bath to break down hard coat prior to planting.
Cannas do best with a good supply of water.
