National Plant Collections: Source of New and Unusual Plant
All of us who collect plants for our personal gardens or for commercial purposes know that many good plants have become difficult if not impossible to find. Not because they have been superseded by better plants, but simply because they are no longer in fashion. Typically, long after these plants have disappeared from commercial catalogs, a new generation of gardeners becomes interested in them and begins to write and talk about them. The demand for these plants increases, Nurseries search for sources, and if we are lucky, the plant becomes a good commercial item. In many cases, however, the plant may have disappeared entirely and exists only as a memory. Many victorian plants, such as, Rosmarinus officinalis ‘Flore Pleno’ and R. officinalis ‘Argentia’, the double-flowered and silver rosemaries, and Myrtus communis ‘Leucocarpa’ and M.communis ‘Flore Plena’, the white-berried and the double myrtles, have gone this route. The true Rosa ×centifolia is only seen in old paintings.
