Greenthreads are annual to herbaceous perennials from the Americas where they prefer rocky, dryish sites in full sun. They make numerous bright lemon yellow flowers on filigree stalks in summer, above ornamental, finely cut, narrow foliage in several species. All Thelesperma species are easily grown in any rich, well drained soil in a sunny spot.
Sow seeds flat in any rich, well drained soil and keep pots outside in a protected spot. Seeds require a prolonged cooling period prior to germination in late spring. Carefully transplant young plants to the final spot in the garden as soon as they are strong enough.
