The Azumi series offers 2–3 1/2" pom-pom style blooms in rich jewel tones on sturdy, vigorous plants. Recommended for growing as a spray-type cut flower. Plants yield one cut per plant; each cut is a large spray of stems and flowers. The primary flower will be larger, surrounded by multiple slightly smaller blooms. Alternately, single stems can be harvested, although stem length will be shorter than when harvested as a one-cut spray type. White blooms open with a creamy center maturing to bright white. Fusarium tolerant.
