What is Exochorda Racemosa?
Exochorda racemosa is a deciduous shrub native to China, part of the Rosaceae family. Its common name, “Pearlbush,” comes from the pearl-shaped flower buds that dangle like delicate jewelry before unfurling into starry white blossoms. Mature plants typically reach 6–10 feet in height with a similar spread, making them ideal for hedges, borders, or standalone focal points.
Key Features:
- Blooms: White flowers in late spring (April–May).
- Foliage: Blue-green leaves turn golden-yellow in fall.
- Growth Habit: Arching branches with a rounded shape.
Popular Varieties of Exochorda Racemosa
While the species itself is stunning, several varieties offer unique traits:
- Exochorda ‘The Bride’: Compact (4–6 ft tall), perfect for small gardens.
- Exochorda racemosa ‘Niagara’: Drought-tolerant with larger flowers.
- Exochorda ‘Blushing Pearl’: Pink-tinged buds add subtle color.
- Exochorda ‘Magical Springtime’: Extended bloom period and disease resistance.
I’ve personally grown ‘The Bride’ in my Pennsylvania garden—its prolific blooms drew compliments from neighbors every spring!

Watering & Feeding
- Watering: Deeply once a week; reduce in winter.
- Fertilizer: Apply balanced fertilizer (10-10-10) in early spring.
Pruning Exochorda Racemosa
Pruning is crucial for shape and blooms:

I learned the hard way that late pruning leads to fewer flowers—don’t make my mistake!

- Diseases: Root rot in soggy soil. Ensure proper drainage.
- Yellow Leaves: Often a sign of overwatering or nutrient deficiency.
