Plant in plain or sandy soil, well drained, full sun or near full sun.  You probably want to prune as your Mexican Sunflower as it grows to create more branching and therefore more flowers.  May need added water after establishment during dry spells

By the way, Mexican Sunflower has a scent and is loved by honey bees and butterflies.  Use for screening, bold color and a specimen plant providing many months of bright yellow during your cool and colder months
