year? my white mountain leucanthemum marguerite is only 9" high; garden tag says it should be 24-32". will it be taller in its second year?
It will probably be taller next year. Be sure it is grown in a sunny spot with well-draining soil. It is drought tolerant once established. Clay soil could stunt the growth.
