Tetradium ruticarpum



Do you ever get the feeling you have just grown too many things? My attention was drawn to Tetradium and T. ruticarpum, a large shrub from China, crossed my path and followed me home.
Unfortunately, I don't remember a single thing about it. I have the picture to demonstrate that it was in the garden (the leaves with it are Impatiens cymbifera growing by my back door). I have a note in my accessions list confirming when and where I bought it, but that is as much as I know. Either it is sitting in the Hedychium house somewhere and I haven't noticed it, or I planted it somewhere and have forgotten it. In either case it will turn up again eventually.

Trees and Shrubs online says:

"Tetradium ruticarpum was apparently not successfully introduced by the earlier generation of plant collectors in China (Flanagan 1988), but recent expeditions have more than made up for the omission and it is now to be found in many collections across our area.
Given its broad range it is not surprising that collections of T. ruticarpum have come from diverse areas, including Taiwan (BSWJ 3541, for example, made in 1996). Tetradium ruticarpum grows rapidly and well, flowering when young. It enjoys the heat of the eastern United States, as evidenced by vigorous trees seen at the JC Raulston Arboretum (planted in 1996 and up to 8 m in 2006), but is also happy with cooler summer conditions. At Tregrehan it has shot up to nearly 10 m in eight years. It can be expected to make a broad-crowned rather than tall tree, however (T. Hudson, pers. comm. 2005). As with T. fraxinifolium, the young leaves are reddish brown but expand to a deep green, that admirably sets off the pale inflorescences. The red fruits are very handsome."
