A pleasing color combination of red and yellow plus a contrast in flower shape makes this combination a great addition to the sunny border in summer. Golden Marguerite begins to bloom in late spring and remains in flower until fall. Cambridge Scarlet joins the scene as summer rolls in and continues to bloom for eight weeks if deadheaded. Both plants like full sun and can do well in medium moist soil. Golden Marguerite is drought tolerant but ‘Cambridge Scarlet’ must not be allowed dry out. Both plants are short lived and susceptible to mildew so profit from good air circulation.
