ROSE PLANT Johan Hendrik Kluis Boskoop, Netherlands; vested in the Alien Property Custodian and Anthony Kluis,

Application May 21, 1942, Serial No.443,971

1 Claim. 1

This invention relates to a new variety of rose, a Rosa polycmtiw, which is a sport of the Polyantha Rosa. Marieanna Kluis Superior, the Polyantha Rosa Marieanna Kluis Superior being a sport of the rose Polyantha Louise Walter.

The new rose was first developed by Johan Hendrik Kluis in his nursery at Boskoop, in the Kingdom of Netherlands, in 1934, by careful selection of specimens of. the Polyantha Rosa Marieanna Kluis Superior and propagation thereof by Johan Hendrik Kluis, during which the present sport appeared. The plant has been reproduced asexually in considerable quantities.

The plant is a dwarf and of a strong growth, reaching a height of about eighteen inches with an average spread of about fifteen inches. It is hardy and flowers from May until November, or

- usually until the first snow of the fall or winter season. The plant is above average in resistance to disease and is exceptionally resistant to mildew.

The foliage is closely set and glabrous, the full grown leaves generally being green, comparable to Maerz & Paul Plate No. 24-J-7, on the upper surface and a lighter green, comparable to Holly Green, Maerz & Paul Plate No. 23-L-1, on the under surface. J The new leaves are a lighter green.

The plant is almost thornless, the occasional thorns being unevenly distributed and of a color comparable to Maerz & Paul Plate No. 22-H-1. They have relatively wide bases with medium long points which curve downwardly.

The flowers are from one to one and one-half inches in diameter and are borne in clusters of four to six on terminals of the main stalk and on strong laterals. The flowers average under normal conditions about thirty-five to forty-five petals each.

The stems are stiff, slender and generally upright and support the flowers well. They are of a color comparable to Biscay Green, Maerz & Paul Plate No. 21-K-5.

The flowers have good lasting qualities and the persistence of the petals on the flowers is above average. The color is uniform and of lasting quality both on the plant and as a cut flower. The flower has the appearance of being uniform in color throughout its extent but examination of the petals discloses differences in color at various portions of the flower. The base of the petals is green with a tinge of yellow, comparable to Maerz & Paul Plate 18-E-1. The central portions of the petals are Geranium Pink or Bermuda, comparable to Maerz & Paul Plate No. l i-8, the outer edges being a color compara to Maerz & Paul Plate l-K-ll, but somewhat more intense. The deeper tone in the shadowpits of the petals is comparable to Maerz & Paul Plate 2L-8. The tips of the bud petals are of a color com parable to Maerz & Paul Plate No. 5-K-4,

The drawin and the following tabulation further illustrate and describe the characteristics of the variety:
