There are many Acer palmatum cultivars, mainly raised in Japan, with all kinds of filigree and coloured foliage.  I’ve found most of them finicky plants that need just the right situation to thrive. ‘Bloodgood’ is far more robust and suited to the rough and tumble of garden life, being able to cope with dry periods and occasional hot sunshine.   The leaves are deep red and turn brilliant scarlet in the autumn.  This cultivar also accepts being pruned better than others, but you must do the pruning when it is dormant, between November and February.
