Canna Lillies are some the most colorful flamboyant summer bulbs with ruffled spikes tapering to refined buds. They are perennials and they come in a wide variety of colors and often have veined leaves in shades of green or bronze. Cannas would be spectacular even if they never bloomed because of their unique appearance. However, the great thing is they keep blooming from late spring or early summer to late fall. They can be grown from seed but it is very difficult.
- Cannas need lots of sunshine and moist soil but they don’t need to be pampered.
- They do best with a good supply of water, so water freely in a dry spell.
- Keep a layer of mulch around Cannas to help retain moisture as well.
- Stake tall varieties if needed.
- As the flowers die, deadhead them to promote continued flowering.
- Every 3 to 4 years in the winter, dig up the clumps, separate the roots, and plant them in well-enriched soil.
- Slugs, snails, spider mites, and caterpillars may be problems.
