Romance blooms when ‘The President’ opens its deep purple blossoms. Expect the first flush of flowers in late spring to early summer, followed by a second blooming with smaller flowers in early autumn. Clematis with classic flower forms like ‘The President’ grow best in full sun to part shade. Prune in late winter or early spring, cutting vines back to 6 to 9 inches tall. Place cuts just above a pair of strong buds. Clematis grows well on a pergola, but flowers may unfurl across the top of the structure, out of sight. Instead, try planting clematis on an arch or fence so you can see the blooms. Deer- and rabbit-resistant plants grow 8 to 12 feet tall by 3 to 4 feet wide. Hardy in Zones 4-8.
