Tulips (Tulipa) form a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs). The flowers are usually large, showy and brightly colored, generally red, pink, yellow, or white (usually in warm colors). They often have a different colored blotch at the base of the tepals (petals and sepals, collectively), internally.
Tulip bulbs look similar to onions, but should not generally be considered food. The toxicity of bulbs is not well-understood, nor is there an agreed-upon method of safely preparing them for human consumption. There have been reports of illness when eaten, depending on quantity.
