Tanacetum haradjanii (Silver Tansy) - A low growing shrublet with grey finely divided silvery 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 somewhat charming, but 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. This plant from Turkey was first described by the Austrian botanist Karl Heinz Rechinger (1906-1998) honoring perhaps Manoog Haradjan but was later reclassified in 1975 as Tanacetum haradjanii by the Scottish botanist Andrew John Charles Grierson (1929-1990)  This description is based on research and observations made of this plant as it grows in our nursery, in our nursery garden and in other gardens that we have visited. We also try to incorporate comments received from others and appreciate getting feedback of any kind from those who have any additional information about this plant, particularly if they disagree with what we have written or if they have additional cultural tips that would aid others in growing Tanacetum haradjanii.
