    Design IdeasClematis is perhaps the most beautiful of all vines for training onto vertical treillage. This ruby colored beauty belongs in courtyards and around outdoor living spaces where the blossoms can be enjoyed close up. They are gorgeous spiraled up wood posts and classical Greek style columns. These plants are also draped over walls and fences in a mass of color. In the Old World they can be found trained into the branches of long dead trees for natural arbor. They are also used as ground covers to cascade down banks and slopes, and to dangle off retaining wall edges.

  • Care
    Care Information
    Thrives in well-drained, slightly alkaline soil, with roots sheltered and top growth in the sun. Mulch soil surface to conserve moisture. Water deeply, regularly in first growing season to establish extensive root system; reduce frequency once established. Feed when new growth begins in spring. Provide support of a trellis or arbor.
    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    History:
    Selected by Boskoop Nurseryman Frans Van Heasteert in Holland, this sport of Clematis x 'Mrs. Cholmondeley' (pronounced Chumley), is a delight. Blooming twice a year with huge soft violet to soft blue, 5 to 6-inch full double-on-double flowers in spring and then semi-doubles in fall, each taking a few days to open to their full glory. After the petals have fallen, wispy seedpods stay on the plant for weeks adding to the drama.
    Lore:
    Clematis is known as the "Queen of Vines" because of its extraordinary flowers that have only gotten larger, more fabulous and numerous over time at the hands of breeders.
