Safety & Hazards

A comment has been made in one report on medicinal uses that the plant should be used with caution[1]. No explanation was given. It quite possibly refers to overuse of the essential oil. All essential oils, since they are so concentrated, can be harmful in large doses[PFAF].

Cultivation Details

HabitEvergreen Shrub
Growth—

Prefers a light, dry calcareous soil and a sunny position[2, 3, 4, 5, 6]. Succeeds in dry soils, poor soils and tolerates drought once it is established[7]. Plants can be grown on old walls. Thymes dislike wet conditions, especially in the winter. A layer of gravel on the soil around them will help protect the foliage from wet soils[8]. Thyme is hardy to about -15°c[9], though it is even hardier when grown on old walls are in well-drained poor light soils[2]. Thyme is commonly grown in the herb garden, there are many named varieties[10]. It is also harvested commercially for its essential oil[11]. The leaves are very aromatic[7]. It is sometimes grown as an annual from seed when used for culinary purposes[9]. The flowers are rich in nectar and are very attractive to honey bees[2, 3, 9]. Thyme is a good companion for most plants[12, 13], it is said to repel cabbage root flies when grown near brassicas[14, 12]. This is a very difficult genus taxonomically, the species hybridize freely with each other and often intergrade into each other[9].

Propagation

Seed - sow spring in a cold frame. Seed can also be sown in autumn in a greenhouse. Surface sow or barely cover the seed. Germination can be erratic. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. The seed can keep for three years in normal storage[2]. Division in spring or autumn[9]. Larger divisions can be planted out direct into their permanent positions. We have found that it is best to pot up smaller divisions and grow them on in light shade in a greenhouse or cold frame until they are growing away well. Plant them out in the summer or the following spring. Cuttings of young shoots, 5 - 8cm with a heel, May/early summer in a frame[9]. Cuttings of half-ripe wood, 5 - 8cm with a heel, mid summer in a frame[9]. Layering.
