Description

The Acanthus hirsutus subsp. syriacus, also known as Syrian Bear's Breech, is a perennial plant appreciated for its foliage and graphic floral spikes. Originating from the Middle East, this rather compact species is drought-resistant and hardy down to -15°C at its lowest. It thrives in Mediterranean gardens or in places where water is scarce. It is an architectural plant, both for its large spiny leaves and its two-tone flower spikes. Best planted in full sun in well-drained soil.

The Syrian Bear's Breech belongs to the Acanthus family, like all acanthus plants. Native to the Middle East, specifically Syria, Lebanon, Jordan, and certain parts of Turkey and Israel, this species naturally thrives in regions with a dry, sunny climate, featuring hot summers and mild to moderately cold winters. It is a deciduous herbaceous perennial, forming dense, spreading clumps from spring onwards, reaching a height of 50 cm when flowering with a width of 60 cm.

Its dark green foliage consists of large lanceolate, pinnate, spiny leaves with a slightly velvety texture. The leaves are arranged in a rosette from the base and quickly stiffen over time. Flowering begins in late spring and extends into summer. The flowers, arranged in spikes, range from greenish-white to pale yellow, with a prominent violet calyx, topped with reddish-brown bracts. These floral spikes can reach up to 50 cm in height, emerging above the low, dense foliage. The deciduous vegetation dries out by late autumn.

The Acanthus hirsutus subsp. syriacus is ideal for border plantings, where its structured foliage and floral spikes stand out. In Mediterranean or dry gardens, it creates an interesting contrast with softer-textured plants. It can be paired with perennials like yarrows, whose flat, colourful inflorescences complement the upright spikes of the acanthus. Hardy Geraniums for rock gardens with pink or violet flowers harmonise with the greenish and yellow tones of the acanthus flowers. Catmints, such as the variety 'Kit Kat' with its small blue flowers and aromatic foliage, are another excellent companion for acanthus plants. These pairings create a vibrant display playing with shapes and textures.

Planting and care

The Acanthus syriacus is hardy down to -15°C approximately (in peak). In regions with cold winters, it is advisable to protect it under a thick mulch that will be removed at the end of winter. This plant requires well-drained soil. However, it appreciates the soil to be fresh during the growth and flowering period. This species thrives in sunny exposures, sheltered from the wind, but can tolerate partial shade, where it will grow taller but be less floriferous. Be careful, like all Acanthus, it does not like to be moved. If you want to prevent it from spreading, cut the flower stalk at the end of fruiting or remove the fruits: beware of prickles, it is better to wear gloves! Like all other Acanthus plants, it is susceptible to powdery mildew in humid climates.
