Frankenia thymifolia (Sea Heath) - A low growing subshrub groundcover to 6 inches tall by 1 to 2 feet wide with wiry creeping stems densely covered with tiny semi-succulent leaves that are rolled back along the margins and have white hairs. In summer appear the very small 5-petaled rose-pink flowers in short spikes at the branch ends.
Plant in full sun in a well-drained soil and irrigate occasionally to very little. Listed as hardy to USDA zone 8 so should be good down to at least to 20 F and maybe a bit less. This interesting plant makes a small-scale groundcover in a well-drained soil or can be used it in the rock or trough garden or as a bonsai companion plant. Frankenia thymifolia comes from southern Spain and north Africa where it is found in saline sites including in Algeria where it inhabits the halophyte steppes leading south into the Sahara and in the sub-sea level salt lake region of Chott Melghirof. This should be a great plant for gardens irrigated with reclaimed water. As the specific epithet implies this plant has foliage much like thyme. Frankenia was named to honor John Frankenius (1590-1661) sometimes written as Franke or Franckenius or Franck, who was professor of anatomy, medicine and botany at Uppsala, Sweden. He was the author of Speculum Botanicum, and a colleague of Linnaeus. The genus is the only one in the family Frankeniaceae which consists of up to a hundred species found in the old and new world in both northern and southern hemispheres. Our thanks go out to Robert Abe of Chia Nursery, who first introduced us to this little charmer.
