The studies were carried out to develop an urban forest aromatic bath in the idle space within city area for handicapped persons, patients and city workers, who having less chance to visit the natural forest aromatic bath. The environmental conditions were checked in the experimental double vinyl house where native and exotic aromatic woody and herbaceous plants were growing with minimum energy input in the periods of mid-winter and mid-summer. The growth and photoperiodic responses of the plants to the low and high temperatures were observed during winter and summer respectively. The most of herbaceous plants in the double vinyl house with the controlled minimum night temperature of $-2^{\circ}C$ had no winter injury but did not grow and started the growth in April. The exotic herbs such as Catnip faassen's(Nepeta x faassenia) and Lemon bergamot(Monarda citriodora) grew better in the longer photoperiodic conditions. The growth rates of Abies koreana, Thuja koraiensis and Pinus sylvestriformis in the early spring were affected mainly by the night minimum temperature and less affected by the photoperiodic conditions during winter. The native aromatic herbs such as Robdosia japonica, Molsa punctulata, Agastache rugosa and Codonopsis lanceolata showed stimulatory growth at the 16 hours day-length in case of the high temperature vinyl hose. The height and root collar diameter growth of pine seedlings were inhibited in maxim temperatures over $40^{\circ}C$ during summer.

The studies were carried out to know shade tolerance of the plants for the urban forest aromatic bath. The one to two year old potted seedlings were grown under the one of the five light conditions such as 100%, 50%, 30%, 10% and 2% of the full sun light intensities. Pinus densiflora S. et Z., P. sylvestriformis (Takenouchi) Chien., Thymus quinquecastatus Celak, Lonicera japonica Thunb, and Zingiber officinale Roscoe showed decreasing tendencies in height and root collar diameter growth, and dry mass production as the light intensity decreases. Exceptionally Thuja koraiensis Nakai showed the best growth in the 50% of full sun light intensity. Athyrium yokoscense (Fr. et Sab.) H. Christ showed better growth in the relative light intensity of 10 to 15% than in the in the relative light intensity of 25 to 30% in the bath green house.
