Lilies are easy to care for and each bulb can grow to become an impressive clump. When selecting lily bulbs to grow, it's important to understand what the different terms to describe them mean. First of all, all plants with lily in their names are not true lilies. Examples would be day lilies or peace lilies. True lilies have distinctive characteristics to help identify them.
