Known as the Red Wrightia, this small tree from the Apocynaceae Family has orangey-red star-shaped flowers that are unfortunately, not fragrant.Its synonyms include Cameraria dubia and Wrightia cambodiensis. This particular plant at Floral Walk is a grafted specimen, as with many others that I saw in Thailand. In fact, this plant is known to be difficult to propagate by cuttings etc.
