Sanvitalia procumbens is a cheerful Mexican annual, with flowers like miniature zinnias. It’s a perfect choice for growing in hanging baskets and containers, as its soft hair stems soon sprawl and become prostrate, forming a solid carpet of bright foliage, studded with the flowers all summer. Almost all varieties are yellow, except for some orange ones. The yellow tones vary between lighter and darker shades. Most varieties are just yellow.
