Aster ‘Syringa Purple’
Botanical Name: Callistephus chinensis
Type: Half-Hardy Annual

Aster ‘Syringa Purple’ is a stunning variety that produces large, fully double blooms in rich purple-lavender tones, resembling the plush texture of syringa (lilac) flowers. Its dense, chrysanthemum-like flowers sit atop strong stems, making it a top choice for cut flowers, as well as adding bold late-season colour to beds and borders. A favourite for both gardeners and florists alike!
