In early summer, the most conspicuous and long lasting flower in the sunny xeric sand prairies is the Hairy Puccoon. The flowers are commonly used by the larger butterflies and moths. The genus name Lithospermum means stone seed, a reference to the large white and hard seeds. Apparently the seeds can remain dormant in the ground for quite a long time, as it is not unusual to see this species quickly recolonizing a sandy lawn area when mowing is ceased.
This plant is a favorite for nectar feeders on the sand prairie in early summer. The bottom photo shows a south facing slope with native sand prairie and L. croceum in bloom - this area is often the site of a coyote den.
