Mariposa lily

Asked July 17, 2019, 1:06 PM EDT

I have bunches of Mariposa Lilies popping up in our 2 acre pasture. If I can get advice on how/when to transplant I would appreciate it. Also if anyone wants some, please let me know. We have been here a year and they were not there last year. I was a Master Gardener in Florida. Thanks! Deb Curlee

Hello Deb,

Thank you for offering your Mariposa Lilies. One of Colorado's many endemic treasures.

Mariposa lilies are of the genus Calochortus, grown from a subterranean bulb.

Provided in the following link are propagation techniques from the Pacific Bulb Society, specifically for Calochortus species:

Provided is another propagation guide from the University of Washington. Note that the list is species-specific, so consult the USDA Plant Database for identification of the lilies on your property.
