Bohemia Ecological Preserve

Cream Sacs in a sea of Hayfield Tarweed. The genus Castilleja contains over 200 different kinds of Indian Paintbrush and Owl's Clover. All are hemiparasitic on the roots of grasses and forbs. Many butterflies feed on their flowers. These plants have a tendency to absorb and concentrate selenium in their tissues from the soil. The roots and green parts can be potentially very toxic - but the flowers are not toxic. Formerly in the Snapdragon Family, now in the Broomrape Family (Orobanchaceae).
