The actual conditions of commercial sales and productions of 2 species of wild Rhododendrons growing on the Boso Peninsula were studied through fieldworks and interviews to gardeners. The results showed these 2 species were treated as the same plant in the marketplace, due to difficulties in visual differentiation. Sales of these plants were at their height during 1982-1985 when they were heavily hunted from their native habitat. The production of seedlings was started in the 1970' s with the great demand for them as garden trees.
