The difference between lily and Lilium lies in their classification and growth characteristics. While “lily” is a common name used for various plants, Lilium refers specifically to a genus of true lilies. These true lilies belong to the family Liliaceae and are characterized by their growth from true bulbs.
True lilies, or Lilium, are a diverse group of flowering plants that encompass numerous species and cultivars. They are renowned for their beauty and are widely cultivated in gardens and landscapes. True lilies grow from bulbs, which are underground storage structures consisting of fleshy scales. These bulbs enable the plants to store nutrients and survive during unfavorable conditions. When planted, the bulbs produce shoots that develop into tall, erect stems with clusters of large, showy flowers on top.
On the other hand, plants commonly referred to as “lilies” but not belonging to the Lilium genus are often misnomers. For example, daylilies (Hemerocallis) and canna lilies (Canna) are not true lilies. They may bear the name “lily” due to their superficial resemblance or the presence of showy flowers, but they belong to different plant genera and have distinct growth habits.
Daylilies, despite their name, do not grow from bulbs. Instead, they grow from tuberous roots. These roots store nutrients and energy for the plants, but they are not true bulbs. Daylilies form clumps of long, strap-like leaves from which flower stalks emerge. The flowers of daylilies are typically trumpet-shaped and come in a wide range of colors, adding a vibrant touch to gardens.
Canna lilies, similarly, are not true lilies. They belong to the genus Canna and grow from thickened underground stems called rhizomes. Rhizomes differ from bulbs in structure and function. They serve as storage organs and produce shoots that develop into leafy stems. Canna lilies are known for their large, paddle-shaped leaves and striking, often tropical-looking flowers.
To summarize the key differences:
True lilies (Lilium):
– Belong to the Lilium genus
– Grow from true bulbs consisting of fleshy scales
– Have tall, erect stems with clusters of large, showy flowers
– Include a diverse range of species and cultivars
Daylilies (Hemerocallis):
– Belong to the Hemerocallis genus
– Grow from tuberous roots, not bulbs
– Form clumps of long leaves with flower stalks emerging
– Produce trumpet-shaped flowers in various colors
Canna lilies (Canna):
– Belong to the Canna genus
– Grow from rhizomes, not bulbs
– Have large, paddle-shaped leaves
– Bear striking, often tropical-looking flowers
It’s important to note these distinctions when selecting plants for your garden or when discussing specific species. While daylilies and canna lilies may share some similarities with true lilies, they differ in their growth habits and plant classification. Understanding these differences can help you make more informed choices in gardening and landscaping.
