Clematis 'Princess Diana' (Princess Diana clematis)

'Alba Luxurians' is a very tough, late-flowering climber with small flowers that open from midsummer to late autumn. White blossoms are sometimes faintly tinged with mauve when young, and are open, bell-shaped, single, and 2 to 3 inches across. Foliage is slightly gray-green.

'Nellie Moser' is easy to grow, producing large, flat flowers 6 to 8 inches in diameter with distinctive, gleaming lilac bars on each petal. This clematis blooms from May to late June, with a second, less profuse bloom in mid-August. Planted in a shady spot, the cheery pink-and-mauve-striped blossoms last for weeks instead of days.

‘Viola’ is, in a word, sumptuous. The velvety, dark purple flowers are exceptional in their profusion and richness. This is a vigorous vine, reaching 10 feet tall, but climbs reasonably well without too much assistance (unlike some other large clematis varieties). Although we grew ‘Viola’ on a chain-link fence—ho hum—I always imagined its richly colored flowers more splendidly displayed against a silvery blue conifer or perhaps intertwined with a pearly white–flowered ‘Huldine’ or a rosy ‘Margot Koster’ clematis. -Richard Hawke, Big blooming clematis, Fine Gardening issue #146, page 50

A clematis doesn’t have to be big to be bold. Picardy™ (‘Evipo024’) epitomizes this rule; its compact habit certainly doesn’t restrain the boldness of the vivid, violet-red flowers. This is no shrinking violet! Picardy™ is free flowering and often reblooms into late summer. Topping out at 5 feet tall, its petite size is suitable for containers and for small patios where larger clematis would be overwhelming. -Richard Hawke, Big blooming clematis, Fine Gardening issue #146, page 47
