Unlike conventional roof landscaping, where various kinds of plants and structures are employed, a grass roof is a roof on which herbaceous plants are grown in planting medium and which is not accessed or maintained, mainly because it doesn't have sufficient load capacity to support a regular roof garden. They are mostly built on existing roofs, whether flat slab or gabled. Planting on roofs has numerous advantages, such as creating a biotope, purifying urban air, adding moisture to the atmosphere, storing rain water, preventing flash floods, reducing energy use for heating and air conditioning, enhancing the urban landscape and providing relaxation to the city dwellers, not to mention the alleviation of global warming by absorbing $CO_2$. In addition to the general merits of roof planting, the grass roof has its own unique qualities. Only herbaceous species are planted on the roof, resulting in light weight which allows roofs of existing buildings to be planted without structural reinforcement. The species chosen are mostly short, tough perennials that don't need to be maintained. These conditions provide an ideal situation where massive planting can be done in urban areas where roofs are often the only and definitely the largest space available to be planted. If roofs are planted on a massive scale they can play a significant role in alleviating global warming, heat island effects and energy shortages. Despite the advantages of grass roofs, there are some problems. The most significant problem is the invasion of neighboring plants. They may be brought in with the planting medium, by birds or by wind. These plants have little aesthetic value comparing to the chosen species and are usually taller. Eventually they dominate and prevail over the original species. The intended planting design disappears and the roof comes to look wild. Since the primary value of a grass roof is ecological, a change in attitude towards what constitutes beauty on the roofscape is necessary. Instead of keeping the roof neat through constant maintenance, people must learn that the wild grass with bird's nests on their roof is more beautiful as it is.

In order to research the effects that indoor plants of apartments in Seoul have on the happiness index, we tried to analyze relationships between indoor plants which are nearest to the residents and happiness which is the final goal of the residents, and for this 200 residents who live in apartments in the Seoul city area were sampled. This study was based on the precedent studies of the facts that horticultural therapy and function of plants had already proven the affirmative roles of plants to people. The results were as follows. Residents reported that they were happiest when the plants were blooming(57%), when the plants were sprouting(33%), when repotting(2%), when distributing(2%) and others(7%). The residents exposed to indoor plants were in direction proportion to the happiness index within 1hour. Happiness indexes of the residents who cared for potted plants were by themselves was 67.90, when family members cared for the plants, 65.09, and when others cared, it was 64.79. The preference of indoor plants and the happiness index according to the scale of interior gardens were in direct proportion. Lastly, the happiness index of residents according to the number of potted plants, was in direct proportion: the more potted plants, the greater the happiness index.

The purpose of this study is, focusing on the ancient paintings and literatures, by examining Flowering Plants and drawing their cultivating methods, to provide a ground of utilizing them on the modern landscaping. In the scope and method of this study, 766 pieces of ancient paintings(6 garden paintings and 760 folk paintings) which were available and had value as literatures, and 8 of ancient literatures were intensively examined. Main results extracted from them are as follows. First, the most frequently used Flowering Plants in Joseon Dynasty were Prunus mume, pbyllostachys, Nelumbo nucifera, Chrysanthemum morifolium, Musa basjoo, Rosa spp., Rhododendron mucronulatum, Paeonia lactiflora, which appeared 11 times to 16 times in total. Next frequently(4 times to 8 times) used Flowering Plants were Gardenia jasminoides, Punica granatum(8 times), Dianthus chinensis, Vitis vinifera(7 times), Orchidaceae, Syringa velutina, Impatiens balsamina, Hemerocallis fulva, Celosia cristata, Hibiscus Syriacus, Rhododendron indicum(6 times), Rhododendron, Rhododendron obutusum, Acorus calamus, Althaea rosea, Kerria japonica, Citrus junos(5 times), Hibiscus mutabilis, Lychnis cognata, Calendula officnalis, Begonia rex., Helianthus annuus, Papaver spp., Narcissus tazetta, Daphne odora, Hosta plantaginea(4 times). Second, usage of the Flowering Plants in Joseon Dynasty can be divided into character building and horticulture for pleasure through positive, scientific approach attempt. It suggests that there might have been classes in the use of them and we can estimate which plants were particularly preferred. Third, in the symbolicity of the usage of Flowering Plants, it can be divided into three parts: The case of representing integrity, gentleman, honesty and nobility and the thought of loyalty and filial piety under the influence of Confucianism. The case of representing Taoism's thought of hermit and perennial youth and long life. The case of representing wish on wealth and prosperity. So if we make a good use of it, we may draw a meaning of cultivation of Flowering Plants from it. This is your target audience or the good luck to all he plants is aimed at, you can see the occurred. Fourth, the Joseon Dynasty was the use of flowering plants are the line of rain wanted to be more consistent with the spirit world. This is shown as a symbol of their ancestors. Joseon Dynasty was used, resulting in a kind of flowering plant and is not a subjective judgement criteria A psychological approach to the side when interpreting the Joseon Dynasty flowering plants to take advantage of the landscape of the area will widen in scope.

With the changing of social needs and paradigms, citizens are concerned about aesthetic and cultural community gardens from productive urban farms in Korea. It is still difficult, however, to cultivate a beautiful garden with a community to design, install and manage it. Therefore, this study analyzed the community garden design guidelines of other countries to derive the characteristics and implications. The research method analyzed six guidelines for community garden design in the UK, Canada, the USA, Australia and Japan. As a result of the study, most community garden design guidelines are opened freely via on-line service. The guidelines are composed with chronological processes such as intro, site selection, design, construction and maintenance. The introduction section treats definition, purpose, meaning, efficiency and success factors for community gardens. Site selection emphasizes site conditions (soil, light, shadow, water, etc.), landholding and insurance. The design section, however, lacks adequate drawings and case images. These guidelines offer little explanation with few illustrations and sentences. Construction sections explain about plantings, facilities, expense and details. The maintenance guidelines of community gardens contain how to control members, funding, harvesting, pests and plants. In addition, some guidelines include vandalism, organic cultivation methods, recording and advertisement. Lastly, the appendix contains a variety of checklists, administrative documents, guidelines, drawings, and contacts. This study will help understand the trends and characteristics of overseas community gardens design guidelines so as to also supply directions for guidelines to be introduced in Korea.

To select fruit trees for urban garden with Elaeagnus umbellata var. coreana, Malus domestica 'Alps Otome', Prunus mume, Ribes nigrum, Rubus fructicosus, and Vaccinium corymbosum 'Reka', growth characteristics of these 6 species were compared and effect of trickle irrigation and shading on the growth of these fruit trees were investigated that these treatments were carried out how much these trees are endurable exposed to improper conditions. After passing the winter, E. umbellata var. coreana, M. domestica 'Alps Otome', P. mume, and V. corymbosum 'Reka' showed the highest survival rate, in contrast to R. nigrum with the lowest of 56.0%. In 9 months after planting, the hight growth rate of 62.3% was shown in P. mume but that of E. umbellata var. coreana was stagnant during experimental period. Flowering rate over 80.0% were shown in E. umbellata var. coreana, M. domestica 'Alps Otome', R. fructicosus, and V. corymbosum 'Reka'. On the other hand, R. nigrum has not ever flowering branches. Other species except E. umbellata var. coreana and R. nigrum have about 10 days in flowering duration. After flowering, fruition rate has shown significant difference among 6 species. As a result of both treatment of trickle irrigation and shading, leaf area and leaf weight of E. umbellata var. coreana, M. domestica 'Alps Otome' significantly inceased with treatments that have not affected other species. Based on these result, it is possible to deploy suitable fruit trees to specific garden condition after selecting various fruit trees.

Species invasions have rapidly increased due to the substantial growth of global trade in the recent past. As the awareness of the negative effects on natural ecosystems derived from alien species has grown, many countries and lawmakers have enacted rules and policies on the conservation of indigenous plants. Unfortunately, in Korea, research on species invasion is seriously lacking despite the growing number of alien species. In the current study, we report alien plants that have intentionally and/or unintentionally been introduced in Korea and also presented a checklist of invasive plants found both in the literature and in field surveys. We reviewed all documented records of alien plants, i.e., scientific papers, illustrated books, and annual reports. We also categorized alien plants by origin, time of introduction, naturalization, and the rate of their spread. The results revealed that there are 619 alien plant taxa (96 families, 353 genera, 595 species, 6 subspecies, 11 varieties, 1 forma, and 6 hybrids) occurring in Korea. Among these, 30 taxa are archaeophytes (Arc.), 214 are potentially invasive plants (PIPs), and 375 are invasive alien plants (IAPs). In addition, IAP taxa consist of grades 5 (widespread, WS) to 1 (potential spread, PS) of alien plants according to the rate of spread in Korea. Our results suggested that the number of alien plants is likely to keep growing; thus, the distribution should be regularly monitored and the list of alien plants must be updated.

This study was conducted to investigate the potentiality of various Korean Sedum species as ornamental plants based on morphological characteristics and to analyze the genetic relationship among the Sedum species. S. kamtschaticum and S. takesimense possessing splendour flowercluster with yellow color could be suggested for garden plant, S. routundifolium having pink flower-clusters with round leaf shape for pot flower or garden plant and S. sarmentosum, S. polystichoides and S. oryzifolium with creeping stem and low plant height for ground cover plant or floral carpet. Eighteen oligonucleotide random primers were used to amplify genomic DNA of Sedum species using polymerase chain reaction (PCR). Ninety five polymorphic bands among 125 different DNA fragments in the range of 224 to 3,675 base pairs were obtained from RAPD analysis. Similarity matrix of RAPD profiles was generated by coefficient value of variation, and the data were subjected to be cluster analysis. Fifteen lines of Sedum species analyzed were classified into 3 groups with the similarity coefficient value of 0.418, and 12 groups with the value of 0.328. RAPD results showed similar trends as the morphological characteristics of the plants.
