Sister Rosie® Scotch Broom

Discover More Information On Sister Rosie® Scotch Broom

Sister Rosie® Scotch Broom (Cytisus scoparius) is a springtime marvel with its palette of dusky pink, red, and yellow blooms. This deciduous shrub pairs wonderfully with bulbs like daffodils and tulips in sunny, dry locations. Hardy across zones 5 to 8, it's not only vibrant but also deer-resistant.

The Sister Rosie® Scotch Broom is both beautiful and practical. Its unique green stems add texture to gardens, making it a standout in borders and container plantings. While it thrives in full sun and well-drained soils, gardeners should be wary of its potential invasiveness in the Northwest and shipping restrictions in some states.

Plant Attributes

The Sister Rosie® Scotch Broom, scientifically known as Cytisus scoparius, is an outstanding deciduous shrub characterized by its medium height, ranging between 24 to 36 inches. This plant proudly exhibits an upright habit, flourishing with an array of vibrant flower colors. Its blooms are a captivating blend of pink, red, and yellow shades, complemented by its lush green foliage.

Ideal for sun-soaked locations, it requires full sun, meaning it thrives best in areas receiving over six hours of sunlight daily. Additionally, it's well-suited for poor, well-drained soils and showcases a notable resilience against drought and salty conditions. Besides being a visual treat, the Sister Rosie® is notably deer-resistant and has low water requirements. However, prospective planters should be informed about its potentially invasive nature in certain regions, and shipping restrictions in specific states.

Landscape Use

The Sister Rosie® Scotch Broom, with its striking blooms and unique texture, offers a plethora of landscaping uses:

  1. Focal Point: Due to its vibrant color palette and distinctive look, this plant serves as an eye-catching focal point in any garden or landscape.
  2. Border Plant: Its moderate growth size makes it an ideal choice for borders, where its rich colors can delineate spaces or paths.
  3. Container Gardens: Its upright growth habit allows the Sister Rosie® Scotch Broom to play the role of a 'thriller' in container gardens, standing tall amidst other shorter plants.
  4. Mass Planting: When planted in groups, the shrub can create a sea of colorful blooms, providing a visual treat in larger landscapes or parks.
  5. Specimen Planting: As a standalone specimen, it adds a touch of elegance and color, especially in minimalist or rock gardens.
  6. Cut Flower: The vibrant blooms can be cut and used in floral arrangements, adding a splash of color indoors.
  7. Textural Accent: The wiry green stems covered in tiny leaves of the Sister Rosie® offer a contrasting texture amidst softer or broader-leafed plants, enriching the garden's tactile aesthetic.
  8. Pairing with Bulbs: It pairs seamlessly with spring-blooming bulbs like daffodils, tulips, and crocuses, creating a synchronized bloom period and a harmonious color blend.
  9. Drought-tolerant Gardens: Given its low water requirements, it's an excellent choice for xeriscaping or gardens designed to withstand dry conditions.
  10. Deer-resistant Landscaping: In areas where deer are a concern, incorporating Sister Rosie® can ensure that the garden remains undisturbed due to its deer-resistant properties.

Planting & Care


  1. Location: Choose a location that receives full sun – this means the spot should ideally get at least 6 hours of direct sunlight daily.
  2. Soil: It thrives best in well-drained soils. While it can tolerate poor soil quality, ensuring good drainage is crucial, especially during cold temperatures.
  3. Spacing: When planting multiple shrubs, maintain a spacing of 24 to 36 inches between each to allow them adequate room for growth and proper air circulation.
  4. Depth: Dig a hole twice as wide as the root ball but no deeper. Place the plant such that the top of the root ball is level with the ground surface. Fill the hole, gently pat down the soil, and water thoroughly.


  1. Watering: The Sister Rosie® Scotch Broom is drought-tolerant, meaning it has a low water requirement. Water sparingly, ensuring the soil doesn't remain waterlogged. In the initial weeks after planting, water more frequently to help establish roots.
  2. Feeding: Given its adaptability to poor soils, heavy fertilization is not necessary. However, an annual application of a general-purpose garden fertilizer can be beneficial.
  3. Pruning: Mostly maintenance-free, but if the plant begins to look untidy or overgrown, a light trim after its spring blooming period can rejuvenate its appearance.
  4. Protection: While the plant is notably deer-resistant, if deer are particularly active in your area, consider using deer repellents or protective netting.
  5. Monitoring: Keep an eye out for any signs of disease or pest infestations. While generally hardy, early detection and treatment can prevent potential issues.
  6. Potential Invasiveness: Be informed about the plant's potential invasiveness in your specific region. In some areas, like the Northwest, it's not recommended due to its aggressive spread.
  7. Winter Care: Although Sister Rosie® Scotch Broom is hardy across zones 5 to 8, in areas prone to severe winter frosts, consider providing some protection with mulch or frost cloths.
