The introduction and growing of new plants is an important part of the nursery industry. New plants result from the discovery of new species — mostly by plant explorers, from mutations of existing known species, or through hybridization.
Every nurseryman constantly surveys his plants in the field and is occasionally rewarded by discovering a superior plant. These are generally variations within the species, but on rare occasions they can be the natural hybrids between even distantly-related species.
When growing plants from seed, the nurseryman has an opportunity to select better strains, and plants grown from seeds selected from these improved strains will generally retain more of the desirable characteristics. Occasionally, even greater variations will occur. Many rhododendrons, azaleas, and kalmias will quite regularly reproduce color shades and plant growth habits similar to those of their parents, if plants of the same characteristics are cross-pollinated or isolated from each
