--><p><i>Asparagus</i> 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 <i>Asparagus</i> and the Asparagaceae.</p><!--
--><p><i>Asparagus</i> virgatus Baker has been collected once as a garden escape in East Baton Rouge Parish, Louisiana, but it is probably not truly naturalized in the flora. <i>Asparagus</i> falcatus Linnaeus occasionally persists after cultivation in the Miami–Dade County area of southern Florida (W. S. Judd 2001).</p>
