A flourishing collection
Miss Elizabeth Allen started to propagate and cross pollinate asters from the 1940s for more than 50 years and grew a large range of cultivars. To maintain the collection, these were then distributed between several gardens - Upton being one of them. Other species went to Paul Picton’s garden at Malvern and some to a private garden near Leeds.
The collection was only finally recognised when it came to Upton and was then classed as such by the National Council for the Conservation of Plants & Gardens, now known as ‘Plant Heritage’.
Asters at Upton
The collection is planted on the West side of the Kitchen garden in three rows so that the plants can be viewed whilst they are in flower. We also have the best cultivars planted in a traditional mixed border together with other late flowering plants to give autumn colour and structure. Asters and Symphyotrichum bring the season of perennials to a climatic end, visited with a late flourish of hover flies, pollen seeking bees and drifts of passing butterflies.
The collection consists of three species of aster amellus, S. cordifolius, and S. ericoides with nearly 100 different cultivars between them.
Aster amellus
Bred in the early 20th century with the introduction of King George in 1914, this has been one of the most popular cultivars ever since.
Its rich, purple-blue flowers are produced relatively early in September. Although purple-blue tones predominate, there are also pink-toned cultivars, such as A. ‘Jacqueline Genebrier’.
Like the true Michaelmas daisies A. amellus cultivars need frequent regeneration by lifting and dividing the clumps every few years.
