Scientific name: thymus vulgaris
Thyme (said like "time") is a small, woody plant with lots of tiny leaves. It grows all year around, and gets tiny pink flowers in the spring. It has a very strong smell, and is used to flavour meat, soups and stews. Some varieties of thyme are lemon scented and can be used in dishes that need a hint of lemon.
Thyme can be grown from seed, cuttings, or just digging up parts of the plant that have already grown roots. When thyme spreads, branches that touch the ground grow roots at that point and are easy to separate. It likes to grow in a hot sunny spot, and can tolerate very heavy frosts and drought. It is a perfect rockery plant.
