(Tithonia rotundiflora) AKA Mexican Sunflower. A beautiful addition to any garden, tithonia attracts butterflies, hummingbirds and other pollinators with its rusty orange blossoms. Plants are multi-branching, continuing to bloom until a hard frost. When planted together in a row, tithonia will form a lovely 5-6 foot tall hedge. For earliest blooms, start indoors in mid-April and transplant out later in May. Farm favourite!
