Description

Aster Azumi XL White (Callistephus chinensis) is a tall, elegant annual variety that produces large, double pompon-style blooms in a clean, crisp white. Each flower measures approximately 7–7.5 cm across, gradually opening into a full, round form with excellent shelf life and durability. The Azumi XL series produces strong, uniform stems that are easier to grow to height than the Matsumoto or Bonita series and features a top-flowering, spray-type habit ideal for professional cut flower production.
