The '''Claret Ash''' or '''Raywood Ash''' is a [[cultivar]] of [[Fraxinus|ash]] tree, a seedling variant of the [[Fraxinus angustifolia|Caucasian Ash]] (''Fraxinus angustifolia'' subsp. ''oxycarpa''). The original seedling was discovered near a group of assorted ash trees in Sewell's nursery in the [[Mount Lofty Ranges]] in [[South Australia]] about 1910, and later grown at the nearby property ''Raywood''. The tree was introduced to [[Great Britain|Britain]] in 1928 and to [[North America]] in 1956, although it did not become widely available there until 1979.
The tree grows to around 15-20 metres and has dark green leaves that turn to a dark claret red in the autumn. The bark of the tree is notably smoother than the Caucasian Ash, which is quite apparent on those trees [[grafting|grafted]] on Caucasian Ash stock.
In [[Australia]] and the [[United States]] a decline or dieback in some older trees has been observed which has been attributed to a combination of environmental stress and the presence of the fungus [[Botryosphaeria]].
