The terminal leaflet is medium ovate in shape with an acuminate shaped tip and cordate shaped base. The terminal and lateral leaflets have a medium frequency of coalescence. The lateral leaflets are medium in size and are narrowly ovate in shape with an acute shaped tip and cordate shaped base. The leaf veins are shallow to medium in depth. The terminal and lateral leaflets have medium waviness of the margin and have medium glossiness of the upper surface. The leaf blades have weak pubescence at the apical rosette. The presence of secondary leaflets is medium.

'Rodeo' has a medium flowering profusion and a small inflorescence size. The flower buds are moderately persistent and have medium anthocyanin colouration. The corolla is red violet in colour with medium anthocyanin on the inner surface. The corolla is medium in size and has a moderately prominent star. The peduncle has strong anthocyanin colouration.

The tip of the light sprout is smaller in size in relation to the base. The tip has a closed habit and has weak anthocyanin colouration. The tip has sparse pubescence. There are a medium number of root tips and the lateral roots are short in length.

Origin & Breeding History: 'Rodeo' originated from a cross between 'Mondial' and 'Bimonda', made in Metslawier, The Netherlands in 1988. Selection criteria included yield, quality, disease resistance and agronomic characters.

Tests & Trials: Trials for 'Rodeo' were conducted in North Tilley, New Brunswick in 2004. A randomized block design was used with four replicates per variety. All entries were planted in single-row plots and each entry had one replicate per block. Plots consisted of rows 5.5 meters long and between row spacing of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the RHS colour chart.
