Aster Needle Unicum Salmon Callistephus Chinensis is an annual aster that can be easily grown from seeds. This China Aster is also commonly called Spider Aster for its unique spider-like flowers. Aster Needle grows up to 24 inches in height producing huge, 3 inch in diameter salmon colored flowers that have striking appearance and bloom all summer and fall until first frost attracting butterflies, bees and other beneficial pollinators.
Aster Unicum is a fantastic addition to any garden, and China Aster is one of the most popular annual flowers for cutting gardens and borders.
