Lilies (genus Lilium) are classic, beautiful, perennial flowers known for their large, often fragrant, trumpet-shaped blooms on tall stems, growing from bulbs with six distinct petals/sepals and six stamens, coming in many colors like white (purity), pink (admiration), and red (passion) and symbolizing rebirth or royalty; while true lilies are Lilium, many other flowers like daylilies and water lilies share the name but aren't related, growing across temperate Northern Hemisphere regions.
