Pyrenaria spectabilis has been in cultivation for a long time, possibly from material collected in the vicinity of Hong Kong, but was treated as a tender glasshouse plant in the British Isles (Chittenden 1951), and seems to have ‘hung on’ in obscurity in a few collections. In Australia and New Zealand, however, it is more widely grown (T. Hudson, pers. comm. 2005), and seed from these countries has been the source of more recent accessions in the United Kingdom, where it is now commercially available. Small specimens growing in a sheltered site outside at the Ghent Botanical Garden in Belgium, accessioned in 2000, were grown from seed obtained by Damien Devos from the Kunming Botanical Garden (J. De Langhe, pers. comm. 2008). These suggest that it is worth attempting beyond the mild coastal extremities of Europe. Pyrenaria spectabilis is potentially a fine evergreen, with attractively pinkish red new shoots. Its big fried-egg flowers are produced in autumn, but plants will require a warm sheltered site for this to occur.
