The demand for aromatic plants is increasing from year to year, due to their wide application in various industries (cosmetics, perfumes, food, pharmaceutical products). Along with such common aromatic crops such as lavender, dill, parsley, celery, fennel, anise, there are many non-traditional crops, which contain oil, but are used less frequently and researches on their introduction, content, economic value haven’t been done.  Monarda is an aromatic, medicinal and ornamental plant with two or three storeys of flowers and it is also an excellent honey plant. Monarda is native to North America, where the plant grows in meadows and forest clearings. The name “Monarda” was given to the genus in honour of the botanist and physician Nicholas Monardes, who wrote a book about New World plants. The experiments were carried out in open field, in balanced conditions, on a general agrotechnical background, without using fertilizers and herbicides. The seeds were sown on plots with an area of 10-20 m2, in March, all at the same time, but, in greenhouses, they were sown in early February.  The vegetative method, by dividing mature bushes, was also experimented with. Phenological observations were performed on 25 plants, every 3 days. The biological material used in the experimental field setting is represented by three species of the genus Monarda L.: M. didyma L., M. fistulosa L. and M. citriodora Cerv.  In the seasonal study, the observations on highlighting the phases of plant development were performed by standard methods. Monarda species is a strong plant that can survive in almost any conditions. It grows best in full sun, but can tolerate some light shade. If the soil is well drained, it does not necessarily need to be very rich in nutrients. If grown in gardens, Monarda attracts bees, which contribute to the pollination of this plant and of those around. The flowering period can be extended and the abundance of flowers can be increased if the withered flowers are removed.  Monarda citriodora Cerv. ex. Lag is an annual species, which grows 25-90 cm tall, with well-developed, branched tap root system. Stems are branched, tetraedged, pubescent. The leaves are opposite, petiolate, lanceolate or oblong-lanceolate, pubescent, with serrated edges, with a strong lemon scent. The flowers are pink-purple, are grouped in 2-7 capituliform, terminal whorls (verticillasters). The fruits are ovoid, glossy nut-like.  Monarda didyma L. is a perennial species with flowering period from July to October. The stem is about 100-130 cm tall. The leaves are opposite, ovate-lanceolate, petiolate, 8-10 cm long. The flowers are irregular, bilabiate, red, arranged in 1-3 capituliform, terminal whorls. On each stem, there are 6-8 inflorescences, with a diameter of 4-10 cm. This species is quite undemanding to growing conditions, being drought and frost tolerant.  Monarda fistulosa L. is a perennial, shrub-like species, which grows 35-120 cm tall. The stem is simple, erect, hairy, reddish at the top. The leaves are strongly flavoured, are large, ovatelanceolate, petiolate, toothed, 3-10 cm long. The flowers are of lilac-purple colour, grouped in terminal whorls; the calyx is tubular. The plants from the variant established by seedling in the experimental year 2014 have determined the highest values of morphological characters examined in comparison with the variants obtained by direct sowing in the experimental field. The M. fistulosa L. plants from the variants established by seedling had the highest values regarding their height measured in the full flowering phenophase.
