Calamagrostis x acutifloraÂ ‘Overdam’ is a very hardy grass which looks good for months, standing tall and erect! It has stripey leaves and pinky seedheads in summer, which in turn change to the colour of wheat in Autumn! I cut this grass back later on in the year, often early spring time, as it looks good Â when covered in frost! I planted these in a new bed last year, and they are growing away quite well, considering the ground in which they’re planted – it’s really heavy clay and it never dries out, even though I’ve raised it a bit. I shall have to top dress over the autumn and cover with more bark and that should help a bit! This grass prefers full sun and a moist soil, but it can be grown in a large pot provided you keep up with the watering! The Ligularia Przewalski to the right of it is colouring nicely now too – and of course enjoying the moist soil! This is a good plant for shade, having lovely erect spikes of yellow flowers on black stems in summer. Growing to around 2 metres it is another erect, tall stemmed plant!
