The tip of the lightsprout of 'Romeo' has an intermediate habit, weak intensity of anthocyanin colouration and sparse pubescence while the tip of the light sprout of 'Chieftain' has a closed habit, strong intensity of anthocyanin and dense pubescence. 'Romeo' has a medium extent of anthocyanin colouration on the flower bud while it is low in 'Chieftain'. The corolla of 'Romeo' is small with a medium extent of weak to medium anthocyanin colouration while the corolla of 'Chieftain' is medium to large with a high extent of medium to strong anthocyanin.
