Evergreen, Ground covers, Shrubs, Semi-evergreen
All bear single flowers with a prominent sunburst of stamens in the center. Shallowly cup-shaped, five-petaled blooms range in color from creamy yellow to gold; flowers may be solitary or in clusters. Neat, fresh green foliage. Various species are used for mass plantings, groundcovers, informal hedges, or borders. Grow especially well in mild, moist regions.
