Chrysanthemum is one of the major crops in the word and it is grown for two basic ways for cut flowers and potted plants, depending of market demand. In the last years the cultivated areas with Chrysanthemum have gained a significant growth. Also, due to the progress made in the selection of chrysanthemum, in order to obtain valuable varieties grown in pots, knowledge of characteristics morphology has of major importance, and the enrichment of the existing assortment in our country is the main objective of the growers. The flowers occur in various forms, and can be daisy-like, decorative, pompon or buttons. In addition, many colors are available, such as white, yellow, red, purple and green. The present paper aimed to study the main characteristics of Chrysanthemum grown in pots of the following cultivars: `Vanilla`, `Eté Indien`, `Camina Red`, `Pamplona Jogger White`, `Amelia Jogger`, `Avalon Salmon`. The measurements of the experiment were focused on the vegetative growth of the cultivars listed above (plant diameter, circumferences of the plant, height of plant, number of stems/plant, number of branches/stem, number of flowers/plant and the diameter of the flowers) in order to diversify the current Chrysanthemum assortment and to promote the cultivation of the most valuable cultivars. The obtained results shown that `Pamplona Jogger White` cultivar registered increases in the case of the diameter, circumference of the plant, and diameter of the flowers. On the opposite side the 'Camina Red' cultivar recorded the largest number of branches/stem and number of flowers/plant and the 'Avalon Salmon' cultivar has the highest values in terms of plant height and number of stems/plant.

Nature, childhood, and ecopsychology can to be connected in the landscape of a schoolyard. The landscape architecture of the natural environments serves as a wide-open green space for outdoor activities, creating imaginative and inventive urban environmental layouts and connecting natural elements. School-based green experience, either indoor or outdoor, can be a physical and mental activity for children. In the case of individuals, it makes` easy to access a natural, green environment and to be actively involved in a natural setting, developing either social and/or cognitive functions and improving concentration and creativity. Therapeutic horticulture activity, such as planting indoor plants, can be a good experience for developing team work, the proprioceptive (kinase) receptors, affectivity, socialization, permanent care, and responsibility. The potential benefits of ornamental plants for children involved in public education include spending time in outdoor spaces, fresh air and sunshine, experiencing a sense of control, and being exposed to sensory stimulations. Physical and psychological education based on therapeutic horticulture activities in Romanian schools, such as planting and green care, can provide important opportunities for children to develop their attachment to nature, offering sustainable education solutions to an active part of the natural environment.

Passiflora genus includes over 600 species native to tropical and subtropical areas of America, appreciated for the production of fruit and medicinal value. Their ornamental potential is especially appreciated in North America and in Europe. With the expansion of the flower trade and the use of secondary metabolites in the pharmaceutical industry, a need for the constant monopolization of new technologies and alternative in vitro techniques that allow to obtain a uniform, high quality material free of pests and diseases occurs. Passiflora's tissue cultures began to be studied in 1966, raising more and more interest of researchers worldwide.Depending on the source and type of the explant, plant growth regulators, and the used genotype, direct and indirect organogenesis are the main regeneration pathways for Passiflora. The latest approaches regarding the choice of explant and its source, the plant material surface sterilization and the specific requirements of each micropropagation stage are presented within our review. To this genus, the reduced gas exchange of in vitro growing of seedlings has been shown as the main cause of lack of success. In this regard, for regeneration and obtained improvements in morphogenesis, different protocols have been developed by using inhibitors of ethylene. In recent years, studies suggest that via somatic embryogenesis, starting from mature and immature zygotic embryos, regenerated plants that have maintained their mother plant ploidy can be successfully obtained. This confirms the callus cultures as main path to obtain in vitro regenerated Passiflora plants.
