We have a 45 degree slope in our backyard that is approx.60 feet by 10 feet that gets sun all day. The hillside had Lantana on it before we had a new retaining wall built. We would like to go with African Daisies but don't know if that is a good choice . The soil is mostly clay after you go down about 6 inches. Can you please tell us if African Daisies is a good choice or give us some other suggestions. thanks.

African daisy (Osteospermum fruticosum) is a good choice for a sunny slope, as are the following:

Bearberry or Kinnikinnick (Arctostaphylos uva-ursi) This evergreen prostrate ground cover creates a mat, spreading and rooting as it creeps out. Delicate light pink flowers appear in winter through spring atop dense leathery green leaves. Leaves turn a reddish tint in winter. Even though this is a slow growing species, it is useful to use on slopes or along retaining walls. Prefers sunny to partially sunny locations. Requires regular water the first summer after planting, and once established, depending on soil conditions will thrive with infrequent summer water.

This plant grows to approximately 1 foot high by 2-3 feet wide

Wild Strawberry (Fragaria chiloensis)
Native to Pacific beaches and bluffs, this plant forms lush, compact mats of dark green, glossy leaves that turn reddish in winter. Tolerates sun along the coast to partial shade inland. Large 1-inch wide white flowers appear in spring. Fruit will seldom set in gardens but in natural setting will produce a seedy fruit in the fall that attracts birds. Annual mowing or cutting back in the early spring will stimulate new growth. Requires little to regular water once established.

This plant grows to approximately 6 ? 12 inches high by 1 ? 2 feet wide

Rockrose (Cistus)
This is a very hardy plant, with showy spring flowers. Accepts poor, dry soil and will tolerate cold ocean winds, salt spray or desert heat. Needs well-drained soil if irrigated. Little to no water is required once established. To keep plants vigorous, an occasional trimming of old stems will induce new growth. Height will vary depending on kind. Shorter varieties are useful as ground cover, in rock gardens, and in rough areas along roads or driveways.

This plant grows to approximately 1 foot high by 2 ? 3 feet wide

Spring Cinquefoil (Potentilla tabernaemontanii)
This tough and persistent plant has a dainty appearance. A tufted creeper, this plant bears clusters of butter yellow flowers in spring and summer. Does well in most gardens and will smother out weeds effectively once established. Makes a good lawn substitute in areas of no-traffic. A fast grower, it is well used as a cover for bulbs. Little to moderate water is required.

This plant grows to approximately 2 ? 6 inches high by 1 ? 2 feet wide

Hope these suggestions help you find just the right plant for your sunny slope.
