[4] In a study of the interaction between pollinators and Albuca flowers, leafcutter bees were observed prying open the tepals and squeezing through to obtain the nectar inside.

[8] Other authorities have considered Albuca in a wider sense, including such genera as Stellarioides, Coilonox, Trimelopter, and Battandiera, for a total of 110 to 180 very heterogeneous species.

[3] All of these genera, including Albuca, have also been lumped together in Ornithogalum at times, but molecular phylogenetics studies support their separation.

[8] The genus, defined broadly, contains about 160 accepted species, according to the World Checklist of Selected Plant Families as of May 2018[update].

Such species are best suited to temperate areas, but can be grown in a conservatory or greenhouse, or in a sheltered position if light frosts might occur.

However, some other species from alpine or Karoo-like areas are fairly frost-resistant and may be deciduous, and accordingly can stand a good deal of frost once established.
