Viguiera laciniata  - San Diego Bush Sunflower, a San Diego endemic species that happens to be excellent for garden conditions. Evergreen, tough and made for full sun conditions, it will still stay green with just once a month or less watering. Trim off dead flowers for another round of blooms. A great choice for almost any San Diego garden, and to showcase local species. Walker Wilson is the founder of Walker's Wildlands nursery in Fallbrook. Walker Wilson - Conservation thr
