Because of my lifelong interest in gardening, I have seen countless breathtaking maples. I have found that the best part about this variety is that it holds its burgundy red colour throughout the season, unlike other maples that turn green.

In autumns leaves fell off, exposing the dark red, beautiful bark that offers winter interest when the rest of the surroundings go dull.
Susan Wood –
My father planted this shrub some years ago. At that time, we had no idea that it would become a perfect garden decor after growing up with its bright scarlet red display.

The tree is there in my friend’s front yard. It offers season long sizzle to the landscape. I planted it a week before in a container, counting down the days to see it flourish.
