Aptitude and tolerance to temperature environment of “Heuchera” as plant for urban greening

Abstract

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.
