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.
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.
