Armand clematis (Clematis armandii) is an evergreen vine common in warm areas. This vigorous climber is covered in fragrant, white flowers in spring. There are a few care problems to consider before planting this vine.
Clematis armandii blooms on old wood, so prune it after flowering in late spring but before mid-July. Extensive pruning is often necessary to thin out the plant's interior.
Armand clematis doesn't compete well with large tree roots. Avoid planting it in flowerbeds under trees.
Hardy in U.S. Department of Agriculture Plant Hardiness Zones 7b through 9, C. armandii can't withstand temperatures below -15 degrees C. Plants killed to the ground sometimes recover in spring if the crown has been protected.
Armand clematis needs moist, well-drained soil. The plant is not drought tolerant and requires supplemental watering during dry spells.
Slugs chew on clematis, so keep the area around the vine clear of plant debris. If you find telltale slug holes, bait the slugs by putting a board on the ground near the plant. The slugs seek shelter from daytime heat under the board and you can pick and destroy them.
