Lycium fremontii occurs in the Sonoran Desert of Arizona, southern California, and northwestern Mexico. Populations of L. fremontii are morphologically gynodioecious (functionally dioecious), and plants are sexually dimorphic for flower size. Pistillate plants are often covered with orange-red berries in March and April. Plants are robust; in southern Arizona they often thrive at the edges of agricultural fields, where there is water run-off. This species co-occurs with L. andersonii, L. berlandieri, and L. californicum. However, the combination of larger bright green leaves, deep lavender flowers, floral dimorphism, and considerable glandular pubescence differentiates this species.
