Erysimum 'Erysistible Yellow' (Pot Size 1L) Wallflower sold by Boma Garden Centre

If you are looking for a wallflower that delivers clean, uncomplicated colour over a long season, Erysimum linifolium ‘Erysistible Yellow’ is a hard plant to pass by. Part of the well-regarded Erysistible series, it produces densely packed spires of bold, pure yellow flowers from early spring right through summer, carried above neat, narrow, dark green evergreen foliage. The Erysistible breeding programme was developed specifically for its controlled, compact habit — this is a wallflower that stays tidy without the tendency to become loose and leggy that can afflict older varieties.The clear, sunny yellow works beautifully in a wide range of planting combinations. Pair it with rich purple Allium ‘Purple Sensation’ or the deep violet of Salvia nemorosa ‘Caradonna’ for a classic complementary contrast, or plant it alongside white Tulipa ‘White Triumphator’ and blue Muscari for a fresh, crisp spring display. In a gravel garden, it sits naturally amongst Stachys byzantina, Lavandula and ornamental grasses. It also performs well in containers and patio pots, providing reliable colour where bolder, taller plants might overwhelm a smaller space. Bees and butterflies are drawn to the open flowers throughout the season.
