Rosa chinensis 'Viridiflora'

This has to be one of the most unusual roses in existence. Supposedly in cultivation since 1743, it was introduced into popular culture in 1856 by a British firm, Bembridge and Harrison. It is believed to be the result of a chance mutation. The strange blooms are made up entirely of sepals rather than petals. It forms a small, tidy bush of about 3 feet in height. It is not hardy in very cold climates. Foliage is a bright clear green with a hint of red in young leaves, and quite disease free. However, one can walk by this plant without even noticing that it is in bloom, because unlike most roses know for their fascinating color, this flower mingles with the foliage. The flowers are apple green, shading to an attractive bronze in cool weather, with an unroselike tufted shape and a spicy, peppery fragrance.
