A choice disease-resistant cultivar of a native California evergreen perennial, 'Marian Sampson' forms a loose mat, good in a rock garden in bright shade, but is especially long-lived in containers. The flower is a knock-out with vermillion brush-like clusters of narrow tubular blooms that shoot straight outward June through August. And the foliage has a wonderful herbal aroma. It needs occasional summer watering; if too dry it will not survive. Hummingbirds and butterflies adore it.Minimum temperature: -40° F
