Monolopia lanceolata, commonly known as hillside daisy or common monolopia, is an annual herb in the Asteraceae family. It is endemic to California, specifically found in the coastal and valley grasslands, chaparral, oak woodlands, and the edges of deserts. This species typically grows to about 31 inches tall with a slender, occasionally branching stem that is often woolly in texture. The hillside daisy blooms from late winter through spring, showcasing small but showy golden-yellow flower heads at the ends of the stem branches.

The hillside daisy is valued for its bright, cheerful flowers that add a splash of color to wildflower meadows and naturalistic garden plantings. It is easy to grow from seed and can be used to great effect in mass plantings for a stunning display of spring color. In cultivation, it prefers full sun to light shade and requires well-drained soils. While it is drought-tolerant once established, additional water during prolonged dry spells can prolong flowering. It is not known for having significant problems with diseases or pests, but it can be short-lived and may need to be reseeded annually to maintain a presence in the garden.CC BY-SA 4.0
