Leucocoryne alliacea Lindl. is a quite cold tolerant species from Chilean regions VI and VII, growing in winter and flowering in spring. Some sources report hardiness down to -15 °C (5 °F). Different images on the web often seem confusing, but can easily be explained with their daily rhythm, as they only open up in the evening and during the warmer part of the night, when they emit the sweet and slightly lemony scent common to moth-pollinated species. In addition to that, they also change considerably with age, growing longer petals and adding a pink tint mostly on the outside of the flower.
Martin Bohnet reports that with his massive variations in April temperatures in Germany, the flowers stay closed if evening temperatures are below about 10 °C (50 °F).
