About Bladder senna
Colutea arborescens, commonly known as Bladder-senna, is a deciduous shrub from the legume family, valued for its striking yellow flowers in clusters and its curious inflated seed pods resembling small bladders. It grows up to 2-4 meters in height and width, with a rounded shape and light green foliage. It is an excellent choice for shrub borders, low-maintenance gardens, or for stabilizing slopes, adding a wild and colorful touch.

Care tips
This species thrives in full sun to partial shade, preferably in well-drained soils, even poor or calcareous ones, making it highly adaptable. It is drought-tolerant once established, requiring moderate watering only during prolonged dry periods. A common mistake is overwatering, which can lead to root rot, as it prefers drier conditions. Pruning for shaping or to remove dead branches is best done in late winter or early spring.
