Clematis 'Ramona' (Late Large-Flowered Clematis)

Large-Flowered Clematis 'Ramona', Clematis sieboldii 'Ramona'


Clematis 'Ramona' is a ravishing deciduous climber which produces an abundance of large, single, pale lavender-blue flowers, 5-7 in. across (12-18 cm) from early to late summer. The star-shaped blooms are blessed with 6 to 8 slightly overlapping tepals and a central tuft of contrasting red anthers. Moderately vigorous, this large-flowered clematis is an excellent choice for covering trellises, arbors, pergolas and walls. Since it blooms on both old and new growth, it may be pruned under Group 2 or 3.

  • Easy to grow and to cultivate, this clematis thrives in moist, well-drained soils, in full sun or part shade. Ideally, Clematis prefer having their 'heads in the sun and their feet in the shade'. Keep the roots cool and shaded by other plants or add a layer of pebbles or flat stones at the base.
  • This clematis can quickly grow up to 8-12 ft. long (240-360 cm).
  • Deadhead after the first wave of blooms to promote new blooms.
  • As climbers, Clematis are unsurpassed in their long flowering presence, their rich diversity of flower shapes, their wide array of colors and tolerances in terms of exposure and climate. It is no wonder they are so popular! From tree huggers to container varieties, there is a Clematis for every garden and flowers for almost every month of the year! Members of the Ranunculaceae family, they include more than 300 species and hundreds of hybrids. They create year after year a ravishing colorful show in the garden whether solely trained on walls, arbors or trellises, or grown in association with other climbers. They are divided into 3 groups which determine how they should be pruned. Regular pruning of Clematis is important as it promotes strong growth and flowering as well as a harmonious plant. If left unpruned, Clematis can turn into a mass of tangled stems with a bare base and flowers well above eye level.
