Gardening is the practice of growing and cultivating plants as part of horticulture. In gardens, ornamental plants are often grown for their flowers, foliage, or overall appearance; useful plants, such as root vegetables, leaf vegetables, fruits, and herbs, are grown for consumption, for use as dyes, or for medicinal or cosmetic use. Gardening is considered by many people to be a relaxing activity.
Gardening ranges in scale from fruit orchards, to long boulevard plantings with one or more different types of shrubs, trees, and herbaceous plants, to residential back gardens including lawns and foundation plantings, and to container gardens grown inside or outside. Gardening may be very specialized, with only one type of plant grown, or involve a variety of plants in mixed plantings. It involves an active participation in the growing of plants, and tends to be labor-intensive, which differentiates it from farming or forestry.
The history of saffron in human cultivation and use reaches back more than 3,000 years and spans many cultures, continents, and civilizations. Saffron, a spice derived from the dried stigmas of the saffron crocus (Crocus sativus), has remained among the world's costliest substances throughout history. With its bitter taste, hay-like fragrance, and slight metallic notes, saffron has been used as a seasoning, fragrance, dye, and medicine. Saffron is native to Southwest Asia, but was first cultivated in Greece.The wild precursor of domesticated saffron crocus is Crocus cartwrightianus. Human cultivators bred C. cartwrightianus specimens by selecting for plants with abnormally long stigmas. Thus, sometime in late Bronze Age Crete, a mutant form of C. cartwrightianus, C. sativus, emerged. Saffron was first documented in a 7th-century BC Assyrian botanical reference compiled under Ashurbanipal. Since then, documentation of saffron's use over a span of 4,000 years in the treatment of some ninety illnesses has been uncovered. Saffron slowly spread throughout much of Eurasia, later reaching parts of North Africa, North America, and Oceania.
