Cleome..A perfect cottage-garden plant, cleome bears spikes of fragrant flowers in shades of white, pink, magenta, and purple. It's so easy, it practically starts itself -- in fact, in many gardens it self-seeds year after year.
Rhodochiton atrosanguineum (AGM) Purple Bell Vine is a deciduous perennial climber with heart-shaped leaves and twining leaf stalks. It bears pendulous tubular deep maroon flowers with bowl-shaped rose-red calyces in Summer and Autumn. It can make a height of 1.5/2.5m but only 1m in spread making it a good candidate for a pergola as shown in this picture. It likes a position in full sun.
