Manfreda was a genus of flowering plants in the family Asparagaceae, subfamily Agavoideae.[1] Along with Polianthes, members are commonly called tuberoses. The generic name honours 14th-century Italian writer Manfredus de Monte Imperiale.[2] All species are now placed in Agave.[3] (See Agave § Taxonomy.)
Like other species of Agave, former Manfreda species have rosettes of leaves branching from a very short stem, and flowers at the end of a long stalk. The flowers are tubular and whitish, yellow, green, or brownish, with lengthy stamens.
