 A flower is the reproductive structure found in flowering plants and its function is to produce seeds of the next generation. The grouping of flowers, also known as bloom or blossom, is called the inflorescence.
In addition to serving as the reproductive organs of flowering plants, flowers are admired and used by humans to beautify their environment, commemorate special lifetime events, and as a source of food.
Flower vegetables include broccoli, cauliflower and artichoke. The most expensive spice, saffron, consists of dried stigmas of a crocus, Hops flowers are used to flavor beer. Marigold flowers are fed to chickens to give their egg yolks a golden yellow color, which consumers find more desirable. Dandelion flowers are often made into wine.
The word flower is from Middle English 'flour' meaning best of anything; blossom from the Proto-Indo-European base bhlo- to blossom, flourish, thrive.

Tulips, family Liliaceae, are perennial plants with large six petaled flowers growing from bulbs. They were introduced to the Netherlands in the 16th century from Turkey, though their origin is central Asia.
The name "tulip" seems to have evolved from the Persian word for turban, perhaps because the open bloom resembles a turban.
