Ceratostigma willmottianum Ceratostigma willmottianum is a compact, deciduous shrub valued for its vivid blue flowers from late summer into autumn and foliage that often colours red in autumn. Forming a rounded mound around 1–1.5m tall and wide, it thrives in full sun and moderately fertile, well-drained soil in Ireland, providing reliable late-season colour for mixed borders and sunny beds. To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images. .icon-container{display:flex;justify-content:space-evenly;flex-wrap:wrap;gap:15px;margin:30px 0;} .icon-description{text-align:center;display:flex;flex-direction:column;align-items:center;width:120px;} .icon-description img{width:40px;height:40px;margin-bottom:5px;} .calendar{display:flex;justify-content:space-between;flex-wrap:wrap;margin-top:30px;border-top:1px solid #ddd;padding-top:10px;} .calendar-month{text-align:center;width:60px;padding:5px;} .calendar-month img{display:block;margin:8px auto 0;width:25px;height:25px;} @media(max-width:600px){.icon-description img{width:30px;height:30px}.calendar-month img{width:20px;height:20px;margin:6px auto 0}} .product-description p{margin-bottom:8px;line-height:1.5} h2{margin:20px 0 10px;text-align:center} .plant-triggers{margin-top:15px;line-height:1.6} Position: Full sun Rate of Growth: Average Soil: Moderately fertile, well-drained soil Hardiness: Fully hardy Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Plant at a Glance light:sun facing:south facing:west soiltype:moderate-fertile soilmoisture:normal foliage:deciduous flowering:august flowering:september flowering:october flowercolour:blue leafcolour:green size:90cm-2m
