Set of 3 or 6 Erysimum Bowles Mauve Evergreen Hardy Perennial Wallflower Plants, Outdoor Garden Ready, 1 Litre / 11cm Root-Ball

Bring long-lasting colour to your garden with this set of three Erysimum 'Bowles's Mauve' plants. Widely regarded as one of the finest perennial wallflowers available, this RHS Award of Garden Merit (AGM) holder produces an abundance of rich mauve-purple flower spikes from early spring well into summer, and often beyond in milder conditions. Its bushy, evergreen habit and narrow grey-green foliage provide year-round structure, while the nectar-rich blooms are a magnet for bees, butterflies and other pollinators.

Each plant is supplied in a 1Ltr root-ball, well-established and ready to plant straight into borders, raised beds, containers or along walls and pathways. Thriving in full sun and free-draining soil, Erysimum 'Bowles's Mauve' is wonderfully low-maintenance once established and tolerant of poorer soils, making it an ideal choice for dry or gravel gardens.
