Asiatic lily
Lilium (Asiatic hybrid)
Asiatic hybrids are the easiest lilies to grow and among the first to bloom — rigid, unbranched 3-4 foot stems carry large, mostly upward- and outward-facing flowers 4-6 inches wide in nearly every color but blue, often with dark basal spotting. The flowers are showy and good for cutting but, unlike most other lily groups, usually have little or no fragrance. Every part of the plant is dangerously toxic to cats.
