Ratibida and Salvia farinacea compliment one another in the garden of Nell Jean at http://www.seedscatterer.blogspot.com/ in the hot, humid depths of Southwest Georgia USA.
Mealycup sage started from seed last year has grown to good size. One clump divided in late winter yielded ample cuttings to fill the bed as they grow on. Only one clump of yellow Ratibida grew from scattered seed; the rest have maroon petals with yellow edges.
Ratibida is complimented by yellow Lantana in the next bed.
