Tanacetum haradjanii (Silver Tansy) - A low growing shrublet with soft finely divided silvery gray-white leaves. It forms a dense mat 4 to 8 inches tall to 2 feet wide or more and produces yellow button-like rayless daisy flowers in loose heads that rise up on short stems in summer. Plant in full sun or light shade in a well-drained soil where it requires very little irrigation - some report it can tolerate clay with careful irrigation scheduling. It has proven perfectly hardy for us and others note it is hardy to below 10 F and useful in gardens down to USDA Zone 6. The flowers are short lived and while somewhat charming, can also be sheared off to retain just the silver foliage look if so desired and a good haircut of the foliage in early spring keeps the plant neater looking. This is a wonderful little plant for dry gardens and stunning when used to contrast with green or reddish foliage or just growing over low rocks or gravel. It is native to the mountains of southern Turkey and northern Syria and was first described as Chrysanthemum haradjanii by the Austrian botanist Karl Heinz Rechinger (1906-1998) to honor Manoog Haradjan, who first collected the plant in 1911 in the Amanus Mountains in Syria near the Turkish border between 5,000 and 6,600 feet in elevation. In 1975 it was reclassified as Tanacetum haradjanii by the Scottish botanist Andrew John Charles Grierson (1929-1990). The name or the genus is an altered form of the Greek word 'athanatos' which means "long-lasting" or "immortal" and refers to the long-lasting dried flowers of Tanacetum vulgare, whose flowers were placed on the dead at funerals. We have grown this attractive and interesting plant since 1989 when we first grew it under the name of Tanacetum densum amani. There are some that still use this name for this plant or call it Tanacetum 'Beth Chatto' after the British plantswoman and landscape designer who popularized this plant. It is also commonly called Partridge Feather.  The information on this webpage is based on research conducted about this plant in our nursery library, from online sources, as well as from observations made of it as it grows in the nursery in containers, in the nursery's garden and in other gardens where we have observed it growing. We will also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing  Tanacetum haradjanii.
