Daff
Daff is a common informal short form of daffodil, the spring-flowering bulb plant in the genus Narcissus. In gardening and horticulture, "daff" is widely used in catalogs, plant signage, and bulletins to denote Narcissus cultivars. Daffodils typically bloom in late winter to spring depending on climate and come in a range of sizes and colors, though yellow and white forms are most common. They are perennial bulbs that naturalize in lawns and borders with minimal care, and are valued for their early-season color and hardiness.
DAFF is an acronym used for government departments in several countries, most notably the Department of Agriculture,
