August Plant of the Month
It’s unusual to come across blue flowers by late summer but this perennial stands out as one of the few to have rich, true-blue flowers. Low growing and mat forming, it also stands out for having leaves that take on shades of red and purple when the temperatures drop in autumn.
Ceratostigma likes full sun or partial shade and can be used as ground cover, although it isn’t evergreen. Height 25cm, spread 90cm. Time to full growth 2-5 years. Hardy in most places in the UK and it has the RHS award of garden merit (RHS AGM).

It caught my eye in the garden of our cottage on holiday in Wales this month. Here it was starting to spill over a low stone wall with Japanese anemone and a hardy fuchsia as a backdrop. A lovely late summer combination.
