Green Santolina is a rounded, fragrant shrub with thin, serrated, fragrant green foliage that is covered with bright yellow button-like flowers in summer. Mostly evergreen but may have some winter damage after harsh winters. Synonymous with S. virens and sometimes called Holy Flax. It needs well-drained soil in the full sun and is quite drought tolerant.  Prune the plant back severely in late winter or spring to keep it from getting too leggy, woody or splitting apart.
