About San Diego County Viguiera (Bahiopsis laciniata) Bahiopsis laciniata is a native shrub of the Aster family that is restricted to coastal southern California and northern Baja. It is very floriferous and blooms over most of the year. It is known by the common names San Diego Sunflower and Tornleaf Goldeneye. It is native to the dry mesas, canyons and mountain slopes as part of chaparral and coastal sage scrub. It is a hairy, resinous shrub growing to a maximum height well over one meter. The leaves have lance-shaped blades up to 5 centimeters long which are glandular and shiny with resin. The blades have smooth or shallowly toothed edges which are sometimes rolled under or crinkled, producing a torn appearance. The inflorescence is a solitary sunflower-like flower head or cyme of several heads. The flower head has several yellow ray florets measuring 6 millimeters to over a centimeter long. The fruit is an achene tipped with a pappus.
