Phlomis purpurea 'Semper Purple' (Purple Phlomis) An upright shrub that grows to 4 feet tall by as wide with upright stems bearing woolly, medium gray-green triangular shaped leaves and lavender-purple flowers with white lower lip that are held in whorls that rise just above the foliage throughout the year with a peak bloom in late spring. Plant in a sunny location in soils of low to moderate fertility that drain well. Will also grow in light shade. This tough plant require very little summer watering once established in coastal conditions but does best with occasional irrigation inland. We have never had any frost damage on our original form of this plant, which we have been told it is hardy to at least 15 F. A great plant for adding gray foliage and pinkish purple flowers to the garden, especially in areas with deer as this plant is avoided by them. Cut back after each flowering period for best appearance. This plant is native to Spain, Portugal and Morocco where it grows on hillsides and in rocky places. The name for the genus dates back to the first century AD from the Greek physician Dioscorides use of the word to describe some plants in the genus and it thought to originate from the Greek word meaning "flame" because the leaves of some species were used for lamp wicks. The specific epithet refers to the typical flower color. While we also grow our original more sprawling form of Phlomis purpurea that has narrower leaves and slightly darker flowers and list it simply as Phlomis purpurea, this form we received from John Low at Sempervirens Botanical in 2015 has a more upright form, larger leaves and a splash of white in the flower and it grows a bit more vigorous with more a uniform and upright form.  The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have visited. We have also incorporated comments received from others and always appreciate getting feedback of any kind from those who have some additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that would aid others in growing  Phlomis purpurea 'Semper Purple'.
