We don't make any apologies for our gushing - this colour combination is one of our favourites, as shown with a shot here from our Hampton Court garden for the APL (Association of Professional Landscapers) in 2017; here we used a CorTen steel water bowl, surrounded by deep crimson Penstemon, fresh green Asplenium and bright-leaved Pennisetum 'Red Buttons'.
Anyway, we digress.....back to the Acer!
We not entirely sure of the variety, but it could be an Acer palmatum 'Osakasuki' which is one of the best Japanese maples to grow for autumn colour.
It has a lovely open habit, tiny flowers followed by red winged seeds, and bright green leaves which turn a brilliant scarlet in autumn; all in all it's perfect for growing as a focal point in the garden. And as it only grows to 4m, it's also great in a smaller spaces.
Just remember when you're planting any Japanese maples to use ericaceous (acidic) compost as this encourages its vibrant foliage colour.
