Looking for a lace leaf with a more upright growing habit? Acer palmatum dissectum 'Garnet Tower' is just such a tree. Not growing as upright like the very unique 'Seiryu' but definitely more so than most dissectums.
'Garnet Tower' has a purple-red colour and a bright red fall colour. A fairly vigorous grower, it may reach 8' tall in ten years. Having grown as a sport on 'Garnet', it shares the similar genetics for colour but adds a little something extra with it's semierect growth habit.
