Bottlebrush
Callistemon citrinus, also known as Crimson Bottlebrush is a shrub in the family Myrtaceae. Though it is not a native of California, it is totally at home here. Frankly it is under valued as a landscape shrub.
It provides tons of ample color, in RED late in the summer when other blooms have long dissappered. It requires low water usage after it is established. It is a favorite of honey bees, and hummingbirds. What is not to like.
Gallardia
Gaillardia (Blanket flower) form wiry, branched stems with lanceolate to linear basal leaves. The plant grows to 1 1/2 to 2 ft tall, with bright daisy-like single color and bi-color blooms in shades from gold to red to brown. The flowers bloom in the late spring and fall. They will grow under very harsh and dry conditions, forming mounds, 8 - 18 inches high.
Gaillardia (Blanket flower) is a genus of drought-tolerant annual and perennial plants from the sunflower family (Asteraceae), native to North America. It was named after M. Gaillard de Charentonneau, an 18th-century French magistrate who was a patron of botany. The common name refers to the inflorescence's resemblance to brightly patterned blankets made by native Americans.
Jupiter's Beard
Centranthus ruber, or Jupiter’s Beard is a popular garden flower. It grows as a perennial plant, usually as a subshrub though it can take any form from a herb to a shrub depending on conditions; the plants are usually woody at the base.
The flowers have a strong and somewhat rank scent: they are pollinated by both bees and butterflies and the plant is noted for attracting insects. Freely reseeds and naturalizes in many places, it can be aggressive if not watched.

Galium odoratum
Sweet Woodruff is a flowering groundcover or spreading perennial for shady sites. Short to medium-sized perennial groundcover, or miniature spreading herb, 6" to 12" tall when in late Spring bloom, but about 4" tall when in foliage, spreading slowly at its perimeter by the procumbent rooting stems, procumbent mat growth habit.
Salvia 'Hot Lips'

Salvia microphylla Hot lips is exceptional in the garden. The bright red and white flowers make a splash in any garden. This Salvia does well in light shade but flowers more prolifically in full sun. Drought stressed leaves turn red. In the ground have gotten about 3 feet tall and twice that wide. They look a little ratty in the winter so cut them back and get an early flush of flowers in March. The plants are almost always in bloom through late Fall when it finally gets too cold.
