No. Canna lilies are members of the genus Canna in the Cannaceae family and grow from rhizomes. They are not true lilies in the genus Lilium, so do not apply Lilium care or toxicity information to them.
Full sun usually produces the best flowers and foliage color. Cannas can tolerate partial shade, but bloom may be lighter; in very hot climates, give them some protection from harsh afternoon sun.
Keep the soil evenly moist while the plant is actively growing and water freely during hot, dry weather. Check containers more often than garden beds, and make sure excess water can drain away.
It depends on local winter temperatures and the cultivar. Canna is a tender perennial, and frost can damage its foliage; cold can injure rhizomes left in the ground. In colder regions, lift and store rhizomes after frost and replant them once frost danger has passed.
Divide crowded rhizomes in spring as growth resumes. Make sure each piece has a visible growing eye, then plant it in warm soil after frost risk has passed.
ASPCA lists Common Garden Canna (Canna generalis) as non-toxic to cats, dogs, and horses. Its entry does not classify every animal or every plant sold as Canna, so keep the botanical label and consult a veterinarian for other pets or a suspected ingestion.
Canna Lily needs bright, indirect light for steady indoor growth.
