What "cultivar" means in gardening

A cultivar, short for "cultivated variety," is a cultivated plant that has been selectively bred or developed by humans for certain desirable traits, such as color, size, growth habit, or disease resistance. Cultivars are typically created through a process of hybridization, mutation, or selection, and are often named and registered with horticultural societies or organizations. They can be propagated through cuttings, seeds, or tissue culture, and are often used in horticulture, landscaping, and agriculture to produce crops or ornamental plants with specific characteristics.
