Cultivars of ACER PALMATUM 
`Bloodgood' holds its red leaf color better than others. 
`Dissectum Atropurpureum' is compact and slow growing. It has finely cut leaves which are deep red. Leaf color fades in time.
`Osakazuki' (shown) has large green leaves that turn bright red in the fall. 

Comments
Japanese Maple is valued for its interesting foliage.  Most varieties are very slow growing and will rarely get over 10 feet tall; however, some varieties can grow up to 25 feet tall. Trees grown from seed lose their red leaf color in summer, which may be disappointing to the homeowner.
