Erysimum Walberton's Fragrant Sunshine ='Walfrasun'

Common name: Walberton's Fragrant Sunshine Wallflower

Description: Erysimum Walberton's Fragrant Sunshine ('Walfrasun') is a superb perennial wallflower producing a profuse and prolonged display of bright, clear yellow flowers with a sweet, classic wallflower fragrance from early spring through to autumn. It forms a compact, mounding evergreen plant that is a reliable and low-maintenance addition to sunny, well-drained borders and gravel gardens. The warm, cheerful yellow flowers are particularly effective in combination with blues and purples, and the plant's tolerance of poor, chalky soils makes it valuable in situations where many perennials struggle.
