Most Mint family plants have a strong fragrance and many are used in the kitchen. Wild marjoram is a relative of oregano, which is famous as an essential ingredient of pizza. The oregano that sits in the spice-rack is actually a combination of wild marjoram stems and its close relatives marjoram (sweet marjoram, knotted marjoram, O. majorana) and Cretan oregano (Turkish oregano, pot marjoram, rίgani, O. onites). Seasoning that is made solely from wild marjoram leaves is sharper and rougher than the oregano mixture. Nowadays oregano is mainly imported into Finland, but islanders in the south-western archipelago have been able to season their fish with wild marjoram before international trade began. Transplanting the species to herb gardens has undoubtedly expanded its habitat. Many special qualities have been attributed to wild marjoram throughout the ages and it was believed to have the power to repel evil spirits and demons.
Wild marjoram thrives on dry, sunny and preferably calciferous land. Like most other Mint family (Lamiaceae) plants, genus Origanum plants are easiest to tell apart by their inflorescence. The flowers that form little cymes are not in paired whorls around the stem but are rather an umbellate spike, forming a corymbose dense, compound cyme. Wild marjoram flowers from July–August, but it doesn’t release its seeds until winter. The woody stem sticks out above the snow, and the seeds can spread further that way.
Sweet Marjoram (Knotted Marjoram, Pot Marjoram)
NOT TRANSLATED YET. Maustemeiramia viljellään meillä jonkin verran kotipuutarhoissa. Sitä on viljelty meillä jo 1600-luvulla ja se on yksi vanhimmista meillä viljellyista maustekasveista. Meillä viljeltävä maustemeirami on yleensä valkokukkaista ja yksivuotista (alkuperäispaikoilla monivuotista), eikä se luonntoomme karkaa vaikka sitä yrittäisimme.
