Bloom season: Yellow daisylike blooms in spring, summer and fall
Pruning needs: None except to shape as desired
Water needs: Low water; once established, water deeply once or twice a month.
Snapshot: Such a funny name, but this ground cover is becoming a low-water favorite. Barbary ragweed is a hardy, evergreen perennial with a spreading habit and unusual, spoon-shaped, upright gray-green leaves. Bright yellow daisylike flowers bloom in spring and early summer. Then, surprise! The flowers are back again in the autumn – much to the benefit of bees. Native to Northern Africa, this plant is useful for the front of a border or for trailing over walls. It also looks good in containers. A sun lover, it likes good drainage and will grow in gravelly soils.
