Manfreda is a genus of flowering plants in the family Asparagaceae, Along with Polianthes, members are commonly called tuberoses. The generic name honours 14th-century Italian writer Manfredus de Monte Imperiale.

Manfreda species, like those in related genera Agave and Polianthes, 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.

Taxonomy

Manfreda and close relatives have long presented significant taxonomic difficulty. With the advent of DNA sequencing, new karyologic and evolutionary phylogenetic studies showed that Manfreda, along with Polianthes and Prochnyanthes, were genetically nested within the traditional circumscription of Agave, rendering that genus paraphyletic.
