Calochortus
kennedyi is native to the pinyon juniper woodland and into the creosote
and joshua tree desert between 2000 and 7000 feet. This photo was
taken at the eastern end of Lockwood Valley. In cultivation
Calochortus kennedyi will require good drainage and a dry Summer. It
is a sad kind of funny but California's native bulbs are used in landscapes more
elsewhere than here.
