Mentzelia lindleyi, sometimes called Bartonia aurea, is a robust, freely branching, slightly sprawling annual some 45cm (18in) high. From mid to late summer it produces a long succession of fragrant, brilliant yellow. These open from gracefully pointed buds into flowers composed of five broad petals arranged around a mass of slender golden stamens. The small narrow leaves are a rich green and set on succulent stems.
This annual is a native of California so it should be grown in full sun. If the weather is cool and cloudy the flowers may fail to open properly. However it does have a reputation for standing up well to wind.
Sow the seeds during early andin a sunny site where they are to flower. They grow best in light fertile soil, though any well-drained soil gives good results. Cover the seeds with just a little soil. Thin to 23cm (9in) apart.
