A Dramatic Architectural Shrub with Deep Purple Foliage

Physocarpus opulifolius 'Diabolo' (syn. 'Monlo') is a stunning deciduous shrub prized for its rich, deep purple foliage that holds its dramatic colour throughout the entire growing season. In early to mid-summer, clusters of delicate, pink-white flowers appear against the dark leaves, creating a striking contrast that adds real drama to any garden setting. As the flowers fade, small reddish seed heads develop, extending the seasonal interest well into autumn, while the peeling, exfoliating bark provides additional texture throughout the winter months, making this a true multi-season performer.

This vigorous and reliable shrub is an excellent choice for mixed borders, specimen planting, informal hedging, or as a bold focal point in larger containers. 'Diabolo' is fully hardy, low-maintenance, and adaptable to a wide range of soil types, thriving in both full sun and partial shade—though its deepest, richest purple tones are best achieved in a sunny position. Supplied as an established plant in a 3-litre pot, it is ready for planting straight into your garden or a generous container.

Key features:

• Dramatic Dark Foliage: Deep purple to dark burgundy leaves provide a sophisticated, bold aesthetic.

• Striking Floral Contrast: Delicate pink-white flower clusters bloom in summer, beautifully offsetting the dark leaves.

• Multi-Season Interest: Features reddish seed heads in autumn and exfoliating bark for winter texture.

• Award-Winning Performance: Proud recipient of the prestigious RHS Award of Garden Merit (AGM).

• Versatile & Hardy: A robust, fully hardy (RHS H7) shrub perfect for borders, hedging, or specimen planting.

Perfect for:

• Creating high-impact focal points in mixed garden borders.

• Wildlife gardens, as the blooms attract bees and butterflies.

• Informal hedging or as a striking specimen plant in a large container.

• Adding seasonal depth, texture, and colour to any garden scheme.

We love 'Diabolo' for its sheer versatility and ability to add instant drama. It is a fantastic, reliable choice that works hard in the garden all year round, providing a sophisticated backdrop during the summer and unique textural interest in the winter.
