Carex tumulicola, the splitawn sedge foothill sedge, or previously Berkeley sedge, is a sedge member of the Cyperaceae family.
Carex tumulicola is found in western North America, from British Columbia to California,. It has a height and width of 2 feet (61 cm), and is slowly spreading. It is found in meadows and open woodlands, below 1,200 metres (3,900 ft).
Carex tumulicola is cultivated in the horticulture trade and widely available as a (grass-like) ornamental grass for: traditional and natural landscape drought-tolerant water-conserving lawns and small 'garden-meadows,' native plant and habitat gardens; and various types of municipal, commercial, and agency sustainable landscape and restoration projects.
Plants grown in the nursery trade are often mislabeled with botanical and common names of similar appearing Carex spp. - while the subtle distinctions are currently  reclarified-assigned by botanists. For example, one considered the species to be closely related to Carex hookeriana, and others to Carex pansa.
