Samaritan ‘BO’ Clematis (Clematis x hybrid ‘Samaritan
™
BO’) is a stunning hybrid variety of clematis known for its bold, large flowers and strong, vigorous growth. This variety is a part of the Clematis Viticella group and is typically appreciated for its vibrant blossoms, which can range from deep purple to rich magenta with a hint of red. It’s a great climber, perfect for growing on trellises, fences, or even in containers.

Care Guide for Samaritan ‘BO’ Clematis

1. Sunlight

  • Full sun is ideal for clematis, as it promotes the best flowering. Aim for at least 6 hours of direct sunlight each day.
  • While the plant enjoys sun, the roots prefer to be kept cool. Plant it with the base in the shade (either by using companion plants or mulch) to prevent overheating.

2. Soil

  • Clematis plants like rich, well-drained soil. A slightly acidic to neutral pH (6.0–7.0) is best.
  • Incorporate compost or well-rotted manure into the soil before planting to improve fertility and drainage.
  • If you have heavy or clay soil, mix in sand or organic matter to ensure that it drains well and doesn’t stay soggy.

3. Watering

  • Water regularly, especially during dry spells. Clematis needs a consistently moist soil, but it does not like to sit in waterlogged conditions. Ensure that the soil drains well.
  • Be careful not to wet the foliage when watering to reduce the risk of disease.
  • Clematis has deep roots, so it’s best to water deeply to ensure that the roots get enough moisture.

4. Fertilizing

  • Fertilize once or twice a year, typically in early spring when new growth begins and again after blooming finishes in late summer or fall.
  • Use a balanced slow-release fertilizer or a specific clematis fertilizer to encourage strong growth and flowering.
  • Clematis prefers low-nitrogen fertilizer, as too much nitrogen can lead to excessive leaf growth at the expense of flowers.

5. Pruning

  • Samaritan

    ‘BO’ is typically a Group 3 clematis, which means it blooms on new wood (the current season’s growth). Prune it back in late winter to early spring (before new growth starts) to about 12–18 inches from the ground.
  • Cut back old wood to encourage vigorous new growth and better flowering in the upcoming season. This also keeps the plant from becoming too woody and unmanageable.
  • Remove dead or damaged stems at any time to keep the plant looking tidy and healthy.

6. Training and Support

  • As a vining plant, clematis needs support for its growth. Use a trellis, fence, or arbor for it to climb on.
  • Clematis tend to be heavy, so make sure the structure you provide is sturdy enough to support the plant as it matures.
  • Regularly tie the stems to the support if needed, as the plant won’t attach itself as tightly as some other vines.

7. Pest and Disease Control

  • Pests: Clematis is relatively pest-resistant but can occasionally be affected by aphids, slugs, and snails. Use organic treatments like neem oil or insecticidal soap if needed.
  • Diseases: Watch for fungal diseases like powdery mildew, particularly in wet or humid conditions. Good air circulation and avoiding overhead watering can help prevent this.
  • Clematis can also be prone to clematis wilt, a fungal disease that causes the plant to droop and wilt. Remove infected stems immediately to prevent the disease from spreading.

8. Winter Care

  • Mulch around the base of the plant in late fall to help protect the roots from freezing temperatures.
  • In colder climates, consider cutting the plant back in early spring (if it hasn’t been done already) to encourage strong new growth.
  • Clematis is generally hardy in USDA Zones 4-9, but it may benefit from extra protection in the harshest winter climates.

9. Propagation

  • Clematis can be propagated by cuttings or layering. Softwood cuttings in the spring are the most common method for propagation.
  • Division is another option if you need to move or propagate your clematis, but it’s not always successful with mature plants.

10. Companion Plants

  • Clemetis looks stunning when paired with other climbing plants, roses, or shrubs like honeysuckle or wisteria.
  • It also works well with low-growing perennials or groundcovers like hostas, asters, or lavender to help keep the roots cool and shaded.


Samaritan ‘BO’ Clematis is a relatively easy-to-care-for plant that can add stunning color and vertical interest to your garden. Its deep, rich blooms make it an excellent choice for trellises, fences, or even containers.
