A new variety of chrysanthemum plant, particularly suitable for outdoor garden culture and for use as a greenhouse pot plant, characterized by its numerous, small, bright yellow blooms which are of single flower form and produced in a relatively open spray formation. This new plant is also distinguished by its excellent performance as a late spring, summer and early fall potted plant and as a natural season garden plant; and by its short, compact plant habit which requires no growth retardants and has excellent breaking ability when manually pinched.
