Lemon Marigold is an attractive, flowering perennial or annual in the aster family. It is often grown for its ornamental value and the foliage, when crushed, is more aromatic than most other plants. The lemon-like smell can remain for an hour or more after touching the plant. Remove dead flowers before seeds form to extend the flowering season. It is often planted as a companion plant in vegetable gardens and grows well with tomatoes.
Lemon Marigold does well in a wide variety of soils, well drained and fertile, including clay, but will not tolerate shade. It can tolerate some dry conditions, but prefers a moist, well-drained environment, water regularly but do not over water. It will grow best from seed that you can start indoors 6 to 8 weeks before last frost date and is also available as plants in six packs from local nurseries. Set plants out after last frost date. Plant taller varieties deep is sites protected from strong wind or heavy rain to minimize the need for stem support.
Insects, Diseases, and Other Plant Problems:
Susceptible to snails, slugs and botrytis.
