Commonly cultivated for their usually large heads of star-like white flowers; occasionally garden escapes or fully naturalized. Ornithogallum arabicum is cultivated in gardens and included in the key below, but is not known to be naturalized in NSW.
This genus has recently been revised (Manning et al. 2009) and some species have been moved to Albuca, including A. bracteata.
