How to grow it
A. rugosa grows well in fertile, moisture-retentive soils and good sunlight. The aroma becomes weaker in shady conditions.
The plant can be propagated by both sexual and asexual means. The seeds gathered in autumn can be sown in the spring. One can also dig out the plant in autumn or early spring, divide the roots, and plant them at intervals of 30 cm (12 in).
