Clerodendrum trichotomum

Clerodendrum trichotomum Thunb. (syn.: Siphonanthus trichotomus (Thunb.) Nakai) (E-As.) – A very rare escape from cultivation. Discovered in 2005 in Roeselare: three young trees at foot of wall, apparently very persistent and subsequently confirmed. In 2006 also observed as running wild (extensively suckering) in a public plantation in Gent (Muide) (compare with Sütöri-Diószegi & Schmidt 2010). Several shrubs were discovered in woodland in Waasmunster in 2013.

Clerodendrum trichotomum is rarely reported as an escape from cultivation in western Europe. Records are available, for instance, from the British Isles (Clement & Foster 1994).
