Thymus

Thymus Species

Thymus is native throughout Europe and much of Asia, from Scandinavia in the north and the Iberian Peninsula in the south west, including the islands, eastwards through western and central Europe, the Mediterranean countries, including north west Africa north of the Sahara, Turkey, Russia, Mongolia and Japan and as far south as the Himalaya.

The following species are generally available from British nurseries and garden centres.  However I do not propagate all of them for sale.

Those marked * are fairly hardy but they dislike winter wet and prefer winter protection in the greenhouse.  Although they will survive outside all year round, they tend to die if we have a very wet autumn or spring and they also grow more healthily in pots.

Those marked † are not hardy and need winter protection in a greenhouse with a minimum temperature of 4°C.  The pots should be taken into the greenhouse at the end of the summer.

Those marked § can be obtained from specialist alpine nurseries.  However they are not easy to grow and should only be contemplated by experienced alpine growers.  They dislike being overwatered in our wet summer weather and need to be kept dry in a greenhouse or alpine house and just have the soil watered when necessary.
