Acer palmatum 'Ryu sei'

Japanese translation means 'Falling Stars'.  This cascading deciduous tree with small green leaves, if grown naturally will become a ground cover.  If staked it will form a narrow weeping column.  Prefers sun/partial shade in well drained soil.   Prefers an eastern exposure sheltered from severe winter weather.  The green leaves turn gold to orange in autumn.  Zone 5
