|For Northern California direct sunlight but protected from winds in the winter, what is the most prolific blooming hibiscus shrub you would recommned? or a few recommendations. We would like to keep trimmed at 4-6 ft. Thanks|
|For your gardening zone I'd recommend the hardy hibiscus (Hibiscus moscheutos). This perennial plant grows in full sun to part shade, flowers in white, pink, or red from summer through autumn and grows to 5' tall in moderately rich, moist soil.
Huge flowers and constant blooms make this a summer show plant. The flowers last only one day, but are continuous through the late summer until the first fall frost. The foliage is deep green, large and heart-shaped. The Hardy Hibiscus requires constantly moist soil and will not tolerate dry conditions.
The most popular variety is ?Kopper King?, with 12? white flowers and a red eye that streaks pink to the petal?s edge. The copper foliage is the result of over 20 years work by the Fleming brothers. These three plant breeders took painstaking effort to develop beautiful flowers as well as ornamental foliage.
?Fireball? explodes in bright burgundy blooms over cut-leaved purple foliage. It looks great planted with ornamental grasses. And even better add ?Old Yella? and pick up on the red eye of this pale yellow variety.
For crisp contrast there is ?Blue River II? with pure white flowers over light green foliage. The foliage on many varieties is cut or lobed like maple or oak leaves giving yet another dimension to this outstanding perennial.
