    Three nonwoven fabrics were compared as bases of matted seedlings on slopes to elucidate their effects on groundcover growth. Groundcovers were transplanted with four species mixed (Lippia canescens, Verbena tenera, Thymus serpyllum, and Sedum sarmentosum). At the nursery stage and after planting on a slope, the groundcover growth was inferior with poly (lactic acid) fiber nonwoven compared to that of nonwoven polyethylene. Afterward until the third year, the total coverage of groundcover plants was maintained over 90% in all treatments. The rate of groundcover composition changed from the first year to the third year. Coverage of S. sarmentosum was high (18–30%) immediately after planting, but it decreased in the second and third years. In contrast, coverage of L. canescens and T. serpyllum increased rapidly, reaching 90–100% during the third year. A significant difference was found in the root penetration of different fabrics.

    Annual bluegrass derived from a putting green (GR) and an orchard (OR) were grown in a glasshouse and compared their morphologies. As a result, the values of plant length, inflorescence length, the number of primary branches/inflorescence, and the number of spikelets/inflorescence of GR were less than those of OR, while the number of florets/spikelet of GR was greater than that of OR. These results suggest that in putting green where annual bluegrass is subjected to excessive mowing and traffic, annual bluegrass may obtain high adaptability by increasing the number of florets/spikelet and downsizing the propagule and inflorescence.

    Heuchera (‘‘Lime Rickey’’, ‘‘Peach Flambe’’, ‘‘Caramel’’) was taken up as plant for urban greening in this research. The relation of the growth between light conditions was investigated. The growth experiment was conducted under a different illuminance condition. As a result, Peach Flambe excels in strong light, and excellent growth was shown in the high illuminance condition. It was possible to endure up to about 15% in a relative low illuminance. Lime Rickey and Caramel caused the leaf scorch phenomenon in 100%, and the growth damage appeared. Best illuminance condition of Lime Rickey was about 35 % and that of Caramel was about 35–50%. Then Lime Rickey was able to endure up to about 15% and it was 5% as for Caramel. However, original beautiful color is ruined under the low illuminance condition.

    Heuchera (‘‘Lime Rickey’’, ‘‘Peach Flambe’’, ‘‘Caramel’’) was taken up as plant for urban greening in this research. The relation of the growth between temperature conditions was investigated. It experimented under the constant temperature condition to clarify optimum temperature regions. As a result, the low temperature was both suitable for growth in the region of 15–30ºC. And it was thought that it was possible to grow enough in summer of Japan. It experimented under the low and high temperature condition, and investigated the low temperature resistance of Heuchera. As a result, Heuchera became clear that it was possible to plant in the large area in Japan.
