Rowan and whitebeam
(sorbus)
On Clemsons Park we have the following:
Sorbus aria - whitebeam: native species. Beam is derived from the German and Old English for tree. The leaves are a light grey green particularly on the underside.
Sorbus aucuparia - rowan: native species. It has several common names including mountain ash.
Sorbus ulleungensis 'Olympic Flame' - a cultivar of Korean rowan (formally Sorbus commixta (Japanese rowan) renamed after recent research). The cultivar has upright branches and rich red autumn leaves.
x Sorbopyrus auricularis - natural hybrid of species from two different genera, Sorbus aria - whitebeam and Pyrus communis - pear: common names: shipova or Bollwiller pear. occured in Alsace,France before 1612.
In Littleover, Sorbus aria (whitebeam) can be seen as a street tree. Sorbus aucuparia (rowan) can be seen as species and varieties in a number of parks and green spaces.. Pyrus communis (European pear) can be seen as orchard cultivars and wild seedlings in Sunnydale and Millennium Orchard.
Here is the explanation of the reclassification of Japanese rowan to Korean rowan.
"In 2014 Sorbus 'Olympic Flame' was re-classified in the species Sorbus ulleungensis. It was previously listed in the long-established rowan species Sorbus commixta which is native to Japan, Korea, and Sakhalin. The change resulted from research into the wild populations of Sorbus species on Ulleung Island, off the coast of Korea."
The RHS now lists Sorbus 'Olympic Flame' as Sorbus ulleungensis 'Olympic Flame' rather than the previous Sorbus commixta 'Olympic Flame'. Sorbus commixta is known as Japanese rowan. Sorbus ulleungensis is known as Korean rowan.
