A new and distinct cultivar of hibiscus plant named DUP-KLK, characterized by glossy, dark green leaves, upright growth, and a very large flower characterized by a large dark burnt orange eye which extends approximately one third of the petal length, the eye sharply margined against an amber zone having an outer margin of bright orange extending to approximately half of the petal length, the outer margin bleeding into a zone of bright straw yellow which extends to the petal edge.

A new and distinct cultivar of hibiscus plant named DUP-PKF, characterized by glossy, dark green leaves, upright growth, and large a large double flower characterized by a lack of an eye zone, or in some cases, an indistinct, extremely faint red blush at the base of the petals extending to about a quarter of the petal length of the outer petal whorl. The ribs of the outer whorl, as well as any petaloids, are a soft pinkish ivory. As the ribs split into venation, they extend through a soft pink body which extends to the petal edge. Doubling petaloids having the same radial color characteristics as the outer whorl are generally present, usually attached low on the staminal column, such as at the base or just above it. Any petaloids originating at higher points on the staminal column are usually much smaller than those with basal origin.

A new and distinct cultivar of hibiscus plant named DUP-STR, characterized by glossy, dark green leaves, upright growth, and a large flower characterized by a large glossy dark red eye which extends approximately one third of petal length, the eye abruptly shading into a strong orange zone extending to the petal edge.
