Getting to Know Acanthus mollis

Acanthus mollis is a perennial plant belonging to the Acanthaceae family. Native to the Mediterranean region, it has become a much-loved ornamental plant in temperate and coastal climates around the world thanks to its dramatic form and relatively easy care.

What Makes Bear’s Breeches So Special?

🌿 Bold, Sculptural Foliage

The most recognisable feature of Acanthus mollis is its large, glossy, deeply lobed leaves. These leaves form a dense clump at ground level and create a striking contrast with softer garden plants.

In fact, these very leaves inspired some of the most famous decorative elements in classical architecture. The ornate leaf designs on Corinthian columnsseen throughout ancient Greek and Roman buildings - are based on the Acanthus plant. It’s a living link between gardening and art history.

🌸 Elegant Flower Spikes

In late spring to early summer, tall flower spikes rise above the foliage. The blooms consist of soft white petals framed by purple or mauve bracts, giving them a layered, almost sculptural appearance. The flowers attract pollinators and add vertical interest to the garden.
