Bloom Time: Spring
Clematis armandii is a climbing plant that grows up to 20 feet (6 m) tall. It bears white fragrant flowers, up to 2.4 inches (6 cm) across, that appear in spring on the previous year's growth. Its dark green leaves droop to create a textured look, and it serves well as a screen.
How to Grow and Care
Clematis vary in their need for pruning. Some types flower on last year's vines, so you want to avoid cutting them to the ground in the spring. Others flower on current-year vines, so they don't mind being cut to the ground each year. Rather than driving yourself crazy trying to keep track of the ideal pruning technique for each cultivar, try this common-sense approach: leave the prior year's growth in place until mid-spring. Begin pruning only when you can see which vines are dead and which ones are starting to leaf out.
A happy Clematis plant puts out an amazing amount of flowers and foliage. Feed your plants well to keep them healthy and vigorous. In early spring, surround the plant with a shovelful of compost and a handful of granular organic fertilizer. Feed again, once or twice during the growing season, with a water-soluble organic fertilizer… – See more at: How to Grow and Care for Clematis
