Acanthus spinosus

Acanthus spinosus, commonly known as Spiny Bear’s Breeches, is a robust and ornamental perennial admired for its distinctive spiny-edged leaves and striking flower spikes. Native to the Mediterranean but well-suited to the Irish climate, this plant combines toughness with architectural beauty, making it a popular choice for gardens throughout Ireland and the UK.

Growing up to 1.5 metres tall, Acanthus spinosus features deeply lobed, glossy green leaves edged with sharp spines, providing natural protection and a unique texture in garden borders or wild spaces. During summer, it produces tall flower stalks with clusters of tubular, cream-coloured flowers tinged with purple, which attract pollinators such as bees and butterflies, supporting local biodiversity.

This perennial thrives in well-drained soil and prefers a sunny or partially shaded position. It is drought-tolerant once established and hardy enough to withstand typical Irish weather, making it a low-maintenance yet striking addition to your garden.
