Leucojum are native to central and southern Europe, from the Pyrenes to Romania and western Russia. They have now also been introduced and have naturalized in many other areas including the East coast of North America.
Leucojum require a moist habitat (like on the edge of natural ponds). Left undisturbed in the same location year after year, they produce more and more flowers. The soil must be high in nutrients and planting them on time in mid Fall is essential to enjoying lots of flowers the following Spring.
