  • the disclosure relates to a new and distinct plant variety of the milkweed (Asclepiadaceae) family. Plants of the new variety are related to and resemble plants of the Hoya carnose variegata variety and also plants of an unnamed variety which are found in the foliage plant market and generally considered to be an improved strain 0f the Hoya carnosa variegata variety.
  • the new plants are comparable to both the unnamed and Hoya carnosa variegata varieties.
  • plants of the new variety have a healthier and more robust appearance when compared to plants of the Hoya car-nosa variegata variety, and in size and shape, the various plant parts closely compare to those of the unnamed variety.
  • the new variety is distinguished from its antecendents and known related varieties in the following respects: (a) by stems, petioles, and peduncles which are characterized by dull, relatively long-lasting red to redpurple hues and which generally appear darker in cornparison to the corresponding parts in plants of the unnamed and Hoya camorra variegata varieties, (b) leaf blades which are characterized by variegated areas with attractive red and pink colors that gradually fade from the areas, (c) by leaf blades which are characterized by green fields that are overcast ⁇ with red to red-purple hues which endow the fields with a blackish or sometimes brownish appearance to the ordinary eye and which gradually fade from the fields, (d) by an infiorescence with attractive purplish-red-colored pcdicels, petals that have an attractive purplish-pink-colored upper epidermis and a purplish-red-colored lower epidermis, sepals with red-purple hues
  • the invention relates to a new and distinct plant variety of the milkweed (Asclepiadaceae) family.
  • Certain plants of the milkweed family are well known in the foliage plant market and among these is the Hoya carnosa variegata variety.
  • the leaf blades of this variety have a variegated or albino area that lacks chlorophyll and which is principally concentrated along the borders of the blades to surround a cetered field of green.
  • plants of this variety have a tendency to produce larger area of variegation in leaves that develop at the first three nodes which appear on new stems and branches, and this frequently results in the appearance of entirely or nearly-entire albino leaves on new breaks that develop from the propagation of stem cuttings.
  • plants of the unnamed variety generally have a healthier, more robust appearance which is generally attributed to the fact that the stems, petioles and peduncles of the unnamed variety are characteristically slightly larger in diameter when compared to those of its antecedent, and that the leaf blades of the unnamed variety are characteristically slightly larger and rounder than the antecedent.
  • the variegated leaf blade areas in both varieties are usually yellowish white, pale yellow or thereabouts in color, and both varieties have a tendency to produce a variegated blade area in an occasional immature leaf which is light pink or thereabouts in color. This light pink color rapidly fades out of the variegated area and it is extremely rare that any of the color can be detected when the leaf reaches maturity.
  • the main object of the invention has been to develop a plant variety which is related in general appearance to plants of the Hoya carnosa variegata variety but which is distinguished by attractive red and pink colors in the variegated leaf blade areas and which appear in successive propagations as a true genetic variation. Yet another object has been to develop a plant variety which fulfills the main objective and additionally has the healthier and more robust appearance that is associated with the unnamed plant variety.
  • Plants of the new variety generally resemble and are related to both the unnamed and Hoya carnosa variegata varieties and are mainly distinguished from its antecedents and related varieties known to the inventor by certain color characteristics.
  • the original plant of the new variety was discovered in a bed of plants which were being propagated from cuttings taken from plants of the unnamed variety and which were under cultivation in a nursery at Winter Garden, Fla. Since the initial discovery of the original plant, the plant has been asexually reproduced at Winter Garden, Fla., by the propagation, at the nursery of stern cuttings taken from the original plant.
  • plants of the new variety have parts which in size and shape closely compare to the corresponding plant parts of the unnamed variety, and that in patterns of leaf variegation, the new plants are comparable to both the unnamed and the Hoya Camara variegata varieties. It has also been ascertained that the tendency to produce more highly variegated leaves at the first three nodes on new breaks has been passed on to the descendant.
  • Plants of the new variety thus generally resemble and are related to both the Hoya carnora variegata and unnamed varieties but are distinguished from these anteeedents and related varieties known to the inventor in the following respects: (1) by stems, pelioles and peduncles which are characteristically slightly larger in diameter as compared to plants ofthe Hoya camorra variegata variety and which are further characterized by dull, relatively long lasting, red to red-purple hues that provide a generally darker appearance in the plant parts as compared to the corresponding parts in plants of the unnamed and Hoya camosa vareaga varieties, (2) by leaf blades which are characteristically slightly larger and rounder as compared to plants of the Hoya carnosa variegata variety and which are further characterized by variegated areas with attractive red and pink colors that gradually fade from the areas and green fields that are overcast with red to red-purple hues which endow the fields with a blackish or sometimes brownish appearance to the ordinary eye and thereafter gradually fade from the
