Bougainvillea spp. a difficult root ornamental plant does not root easily requiring the need for growth regulators. Moreover, the varieties have high aesthetic values and commercial florist desires. Experiments were conducted at the Federal University of Agriculture, Abeokuta Nigeria to determine the effect of varietal differences and cutting length on the rooting ability and growth of Bougainvillea plants. The experiment was a completely randomized design replicated three times. The cutting lengths had a significant effect on the number of leaves produced, with the highest leaf production observed for the 15cm cutting lengths in B. glabra variegata and B. glabra white plants, 5cm cuttings however produced the highest number of leaves in B. spectabilis variety. The cutting length also has a significant effect on the heights produced in the three varieties of Bougainvillea plants where 15cm cutting produced the highest plant heights in B. glabra variegata and B. glabra white varieties which were significantly different from those obtained from the 10cm cuttings, However, 5cm cuttings produced the highest plant heights in B. spectabilis. The interaction effect of cutting length and variety was significant (p
