Santolina rosmarinifolia (Green Santolina) - A neat rounded aromatic evergreen shrub that typically grows 1 to 2 feet tall and as wide but when happy can get a little larger. It has deep green narrow leaves that are pinnately divided into tiny segments. The pale yellow rounded composite flowers appear in the mid to late spring. Plant in full sun in a well-drained soil and irrigate only occasionally. It is drought tolerant and hardy to 0 F or slightly below. Though often used in knot gardens and trimmed to keep low, consideration should be made to its requirements of good drainage and careful irrigation practices. Overwatering of this plant or plantings in poor draining soils often result in root rot, but a well-established plant thrives with little to no supplemental irrigation and be very attractive in the garden. Shear lightly in early spring to keep dense and dead head spent flowers. This useful garden plant hails from the Iberian Peninsula (Spain and Portugal) into Southern France. The name for the Genus comes from the Latin phrase 'sanctum linum' which means "holy flax", a name applied to one of the green species of Santolina for its medicinal qualities and the specific epithet means foliage like a rosemary. This species is sometimes listed as Santolina ericoides, an older synonym for Lavender Cotton which is the gray S. chamaecyparissus. It is also sometimes referred to as S. virens (or S. viridis) and sometimes as S. pinnata. The name Santolina rosmarinifolia was given to this plant by Carl von Linnaeus in his Species Plantarum 2 in 1753. We have grown this great plant since our nursery first opened in 1979 and we also grow the gray Lavender Cotton, Santolina chamaecyparissus and Santolina neapolitana 'Lemon Queen'.  The information provided on this page is based on research we have conducted about this plant in our nursery's library, from what we have found about it on reliable online sources, as well as from observations in our nursery of crops of this plant as well as of plants growing in the nursery's garden and those in other gardens. We will also incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing  Santolina rosmarinifolia.
