100 (150)cm and 200 (300)cm, Flor de Chuvisco or Orange Cosmos (syn. Bidens sulphurea) is a beautiful Mexican annual with bright orange to rich yellow flowers above dissected leaves on tall, branching stems. Sow directly to the ground after the last freezing night in spring. Easily cultivated in any rich, well drained soil in full sun. We offer a mixture of seeds from the regular form with seeds from a polyploids, extremely tall growing form. This will give you flowers form early summer (regular form) to autumn (polyploid form). VI-IX.
