Sister Redhead Scotch Broom has bright red pea-like flowers that are kissed with a tiny bit of gold making those flowers stand out even more! This beauty is a standout in any garden in the spring. Her upright growth showcases the beautiful blooms and planted with other spring blooms such as golden daffodils just increases her attractiveness.
This redhead loves hot and sunny spots in the garden. It is insect and disease and deer resistant as well. It is drought and salt tolerant, making it ideal for those coastal areas too. This Scotch Broom is an upright growing shrub just 3-4 ft. tall and 2-3 ft. wide. You can use it in containers as a thriller or in the garden as a focal point or in a mass planting. It’s called a Scotch Broom because the growth habit is upright like a broom.
Sister Redhead® Scotch Broom Care
‘Sister Redhead’ prefers a well-draining, low fertility soil and sunny spots for best growth. It thrives from Zone 5a- 8b. No pruning is necessary unless there is a broken branch or it becomes too open. In that case just a light trim after it is done blooming in mid spring.
You can use branches of ‘Sister Redhead’ in flower arrangement either in bloom or just foliage. After it blooms the plant leaves small pea-like seed pods that are attractive.
Sister Redhead® Scotch Broom Spacing
Plant Sister Redhead Scotch Broom 3 to 4 feet apart, center on center. If you are growing into a garden border or small hedge, plant closer to 3 feet apart. Use the same spacing away from other plants and structures as well. Proper spacing will ensure the plant gets enough air circulation and sunlight. It also gives the roots enough space to grow, even when the plant reaches mature size.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
