Most of the Symphyotrichum novae-angliae cultivars included on this page have been growing in the Picton Garden as part of the Royal Horticultural Society trials. The purpose of the trials is to assess the cultivars in order to recognise the most garden worthy plants.
New England Asters, Sympyhotrichum novae-angliae, are easy to grow, long lived, hardy herbaceous perennials. Their flowering season runs from early September into mid to late October. The majority of cv’s will grow up to between 90cm and 135cm in height. A few are shorter and some can grow as tall as 180cm. All will grow best in an open, sunny situation in well cultivated soil.
