Yarrows are variable low-growing, spreading herbaceous perennials with finely divided leaves that inhabit many temperate regions in the Northern Hemisphere. Flattish clusters of flowers form in spring and well into summer and provide an important nectar source for pollinators and insects. Yarrow can help to stabilize slopes and is a good addition to the upper level of rain gardens and swales. Colors include yellow, pink, and red.

California native spp & cvs: A. millefolium (common yarrow), A. m. ‘Calistoga’, A. m. ‘Island Pink’, A. m. ‘Sonoma Coast’, A. m. ‘Terracotta’.

Other yarrows: A. filipendulina (fern leaf yarrow), A. f. ‘Coronation Gold’, A. ‘Moonshine’, A. tomentosa (woolly yarrow).

Ceanothus is a group of fast-growing, evergreen shrubs that vary from groundcovers to small trees, many of which are native to California. They provide a spectacular display of flowers in spring that will attract a multitude of pollinators. Flowers are followed by seeds that provide food for birds. The clusters of tiny flowers range from white to deep violet. Plants perform best with good drainage and minimal irrigation once established. Some do best in cooler coastal climates, but many thrive in hotter inland climates. Pay close attention to the mature size when selecting ceanothus to ensure that it has sufficient space for its natural form.

Groundcovers: C. ‘Centennial’ (1’ x 8’), C. gloriosus var. gloriosus ‘Anchor Bay’ (2’ x 8’), C. griseus var. horizontalis ‘Diamond Heights’ (variegated, 1’ x 4’), C. griseus var. horizontalis ‘Yankee Point’ (3’ x 12’), C. maritimus (2’ x 6’).

Shrubs: C. ‘Blue Jeans’ (6’ x 6’), C. Concha (6’ x 6’), C. ‘Dark Star’ (6’ x 8’), C. ‘Joyce Coulter’ (4’ x 12’), C. ‘Julia Phelps’ (8’ x 10’), C. cuneatus (8’ x 8’), C. thyrsiflorus ‘Skylark’ (4’ x 6’).
