Potentilla ‘Pink Whisper’ (Potentilla fruticosa 'Pink Whisper') is a compact, deciduous, and hardy flowering shrub (USDA Zones 3–7) known for its delicate pale pink, cup-shaped flowers that bloom from summer to autumn. It reaches 2–3 feet in height and width with a mounded, bushy habit, featuring fine-textured, light green foliage. It is ideal for borders, low hedges, and foundation plantings. 
Flowers: The blossoms are a soft, pale pink, sometimes fading to white or buff as the season progresses or in hotter climates.
Hardiness & Growth: Extremely hardy (Zone 2-7), featuring a moderate growth rate and a tidy, rounded form.
Light: Prefers full sun for the best blooming performance, though it can tolerate light shade.
Soil & Water: Thrives in well-drained soils and is drought-tolerant once established.
Maintenance: Low-maintenance; can be pruned in late winter or early spring to maintain its shape and encourage new growth.
Uses: Excellent for low, flowering hedges, perennial borders, and mass plantings due to its long-lasting, continuous, or repeat-blooming nature. 
It is highly regarded for its resistance to deer and adaptability, although it may struggle in areas with extreme heat and humidity.
