'Golden Tiara' is a vigorous, late-flowering climbing vine to 15 or 20 feet tall with intense golden-yellow, bell-shaped flowers that eventually fully open to reveal crimson filaments. It blooms profusely from midsummer to late fall. The seedheads are fluffy and attractive in their own right. Native to western China.

A half-hardy perennial, this sophisticated climber grows to 8 feet tall. It has a profuse show of 1.5-inch indigo, violet, pink, or white flowers. It's great for the cold greenhouse or conservatory, and will often bloom until the end of the year unless there is a hard frost.

Clematis integrifolia is a herbaceous, woody-based, upright, non-climbing perennial with a dense and somewhat sprawling habit. It bears solitary, nodding, bell-shaped flowers with slightly twisted violet to blue sepals and creamy white anthers from May to July. Sporadic blooming sometimes occurs throughout the summer. Blossoms mature to attractive, feathery, silver-green, or silvery brown seed heads.

'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.
