'Trier' in commerce is sometimes 'Moonlight' and vice versa.
Combined Rose List 2006: "note that the rose sold under [the name Trier] by many European nurseries is Moonlight." To be correct Trier is sold by some Nurseries in the USA as Moonlight and should not be confused with Pembertons Moonlight.
Trier bred by Lambert should not be confused with Trier 2000 by Kordes. Lambert was working in 1904 in the German city of Trier after which the rose is named.
