[header] How to plant clematis [title] Pick a clematis cultivar. [step] Clematis flowers come in an enormous range of shapes and colors, from pink blooms that span 6 inches across to drooping blue bells to starry white flowers. They've grown in popularity in recent years, so many nurseries offer dozens of varieties to choose from. 
When you decide which cultivar to buy, take the color, shape, potential side and sun requirements into account. Clematis often take several years to flower, so look for a potted plant that's already a year or two old.
