The detail
You can choose from a refined selection of Aster Alpha colour forms, including deep dark purple, soft light pink and clean, crisp white. Each variety produces masses of classic daisy-like flowers with bright golden-yellow centres, held above bushy clumps of fresh green foliage that remain neat and well-structured throughout the season. Flowering prolifically from late summer into early autumn, these asters provide strong contrast, texture and colour at a valuable point in the gardening calendar. With a naturally compact, upright habit reaching around 30–40 cm tall & wide, they are ideally suited to borders, front-of-bed planting, containers, baskets and mixed perennial displays.
All plants are supplied as large, well-established, garden-ready 2-litre rootballs in their nursery pots, professionally grown in premium peat-free compost to ensure strong root development and reliable establishment after planting. Larger and more robust than typical retail alternatives, they are delivered at the optimal growth stage, allowing them to settle quickly and perform confidently when flowering season arrives. As hardy perennials, these Aster Alpha varieties return year after year and provide a valuable late-season nectar source for bees and other beneficial insects.
