Leucocoryne  is a Chilean endemic genus from the Amaryllidaceae family. It is an emerging crop with some registered varieties, currently oriented to a niche ornamental market. In the present work, seed germination in  Leucocoryne dimorphopetala ,  Leucocoryne coquimbensis ,  Leucocoryne purpurea ,  Leucocoryne  aff.  vittata ,  Leucocoryne  aff.  violacescens , and  Leucocoryne ixioides  for seeds stored for 4 months and in  L. purpurea ,  Leucocoryne vittata ,  L . aff.  vittata , and  L. ixioides  for seeds stored for up to 16 months was analyzed at 10, 15, 20, or 25 °C. Germination data were analyzed by the previously developed time-germination model  p = A {1 −  exp [− k ( t  −  t  0 )]}. Each germination curve had a coefficient of determination ( R  2 ) higher than 0.89, except when there was lack of germination. Results show that higher germination was better achieved at lower (10 or 15 °C) rather than at the higher temperatures (20 or 25 °C). When comparing germination results at temperatures of 10 and 15 with results at 20 °C, germination decreased by at least 30% and became near zero at 25 °C in seed stored for 4 months. Similarly when seeds were stored for 16 months, germination decreased by ≈20% at 20 °C, and again was near zero for germination at 25 °C. These germination habits of  Leucocoryne  are interpreted as an adaptive strategy to its natural habitats. In addition,  L. dimorphopetala  presents a type of dormancy and other species ( L. purpurea ,  L. ixioides , and  L.  aff.  vittata ) may be sensitive to after-ripening changes during storage.
