Asiatic lilies are hybrids, not true lilies like the golden-rayed lily (Lilium auratum), Easter lily (Lilium longiflorum), and Madonna lily (Lilium candidum). Asiatic lilies don't require pruning.
Adorned by many for their bright colors and long blooming season, Asiatic lilies (Lilium-Asiatic hybrids, formerly Lilium asiatica) release their star-like blossoms early in the season.
