About

Aster Seeds for Colourful Cut-Flower Gardens Grow abundant late-summer flowers for bouquets, borders, and pollinator-friendly gardens with our collection of aster seeds . Asters are loved for their full, daisy-like blooms, broad colour range, and ability to provide valuable garden colour as many earlier flowers begin to fade. Our collection focuses primarily on annual China asters, botanically known as Callistephus chinensis . These productive cut flowers are available in soft apricot, blush, lavender, pale blue, silver, white, yellow, rose, chamois, and mixed colours. Depending on the variety, flowers may be rounded, incurved, quilled, or densely petalled. Growing asters from seed allows gardeners to choose specific flower forms and colours that may not be available as established nursery plants. Plant a coordinated colour palette for wedding or event flowers, combine several varieties for mixed bouquets, or add asters to a succession-planted cutting garden for flowers later in the season.
