Ceanothus impressus the edges. They may be gland-dotted and have grayish hairy undersides. The shrub flowers abundantly in inflorescences of small blue flowers. The fruit is a crested spherical capsule about 4 millimeters wide. Ceanothus impressus Ceanothus impressus, with the common name Santa Barbara ceanothus, is a species of flowering shrub. This "Ceanothus" is endemic to the Central Coast of California, where it can be found on coastal slopes and mesas. Other common names are blueblossom ('blueblos') and California lilac, although the plant is not a lilac ("Syringa"). This expansive shrub may exceed three meters-10 feet in height and approach seven m.-28
Flowering plant The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae. The internal classification of this group has undergone considerable revision. The Cronquist system, proposed by Arthur Cronquist in 1968 and published in its full form in 1981, is still widely used but is no longer believed to accurately reflect phylogeny. A consensus about how the flowering plants should be arranged has recently begun to emerge
