Asparagus is a moderately important horticultural genus, with one species commonly grown for its edible young shoots and a number of others grown ornamentally. The genus is treated here in a broad sense (K . Kubitzki and P. J. Rudall 1998; W. S. Judd 2001) and encompasses species that have been segregated in several genera (A. L. Takhtajan 1997; S. T. Malcomber and Sebsebe D. 1993). Embryological features (P. J. Rudall et al. 1998) and DNA-based analyses (M. W. Chase et al. 1996; M. F. Fay et al. 2000; P. J. Rudall et al. 1997) support the monophyly of Asparagus and the Asparagaceae.[1]

Habitat

Typically found in water with a depth of 0 to -44 meters (0 to -144 feet).[2]

Biome: Marine .
