Clematis pitcheri: Unveiling the Charm of Purple Leatherflower

Background and Origin: Clematis pitcheri, also known as Purple Leatherflower, is a herbaceous, perennial climber belonging to the family Ranunculaceae. This delightful clematis is native to the central and south-central regions of the United States, as well as northern Mexico. It thrives in diverse habitats such as wooded rocky outcrops, woodland margins, bluffs, road cuts, and fence rows. The specific epithet “pitcheri” pays homage to Dr. Zina Pitcher, a renowned surgeon with the United States Army and botanist known for his work in the Great Lakes region.

Characteristics and Description: Clematis pitcheri is a captivating vine that features twining, delicate stems reaching impressive lengths of 10-13 feet. The leaves of this clematis are highly variable and arranged oppositely along the stems. They can be either simple or compound, with compound leaves consisting of 2-8 leaflets. The leaflets themselves may be entire or lobed, showcasing a range of shapes from ovate to lanceolate.

From late spring to summer, Clematis pitcheri adorns itself with enchanting, solitary, nodding flowers. These urn-shaped blooms, approximately 1 inch long, boast showy sepals that vary in color from purple to blue. The tips of the sepals curve backward, exhibiting slightly ruffled margins. The flowers of Clematis pitcheri primarily attract bumblebees, providing a haven for these beneficial pollinators.

Following the floral display, this clematis produces ornamental seedheads that add further visual interest to the plant. The fluffy seedheads mature from light green or dark red to dark brown, forming clusters and resembling delicate spiders with their slightly hairy tails. These seedheads often persist through winter, offering a unique feature to enjoy during the colder months.

Cultivation of Clematis pitcheri:

To successfully cultivate Clematis pitcheri, consider the following guidelines:

Sunlight: This clematis thrives in moist, well-drained soils when grown in full sun or part shade. Ideally, it is recommended to provide a location where the clematis can enjoy the sunlight on its blooms while keeping its roots cool and shaded. This can be achieved by planting it alongside other taller plants or adding a layer of pebbles or flat stones at the base.

Watering: Maintain even moisture levels by providing adequate watering. While Clematis pitcheri exhibits some drought tolerance, regular watering is essential, especially during dry spells, to ensure the plant’s vitality.

Soil: Clematis pitcheri is adaptable to various soil types, including rocky and sandy soils, as long as the soil is well-drained and evenly moist. It thrives in soils with good drainage and benefits from organic matter amendments.

Pruning: As part of Group 3 in the Clematis classification, Clematis pitcheri blooms on new growth produced in the same season. Therefore, it should be pruned in late winter or early spring before new growth emerges from the rootstock. Engage in “hard pruning” by cutting back the stems to a pair of strong buds, leaving about 1 foot (30 cm) above ground level.

Pests and Diseases: While Clematis pitcheri is generally considered relatively pest and disease resistant, it’s essential to monitor the plant for any signs of common issues. Aphids, slugs, and snails can occasionally pose a threat. Take appropriate measures, such as employing insecticidal soaps or organic pest controls, to address any infestations promptly.


Propagation of Clematis pitcheri can be accomplished through various methods, including:

  1. Seeds: Collect the mature seeds from the fluffy seedheads and sow them in a well-drained potting mix. Keep the soil consistently moist and provide warmth. Germination typically occurs within a few weeks.
  2. Softwood Cuttings: Take softwood cuttings in early summer and root them in a suitable rooting medium. Maintain high humidity and provide bottom heat to encourage successful rooting.
  3. Layering: Choose a healthy, flexible stem and bend it down to the ground. Make a small wound on the stem where it contacts the soil, ensuring it remains in contact with moist soil. Once roots develop, sever the layered stem from the parent plant and transplant it to a desired location.

Clematis pitcheri, with its nodding purple to brick-red flowers, alluring seedheads, and graceful climbing habit, brings a touch of elegance to any garden. By following the recommended cultivation practices, including suitable sunlight, watering, soil, and pruning, you can enjoy the beauty of this herbaceous perennial climber year after year. Embrace the charm of Purple Leatherflower and let it enchant your landscape with its enduring grace.
