It's surprising what a few years can do to a garden. When I first started this client's garden it was one muddled mess and to be fair, very poorly maintained and no thought whatsoever regarding successional planting. This was a picture during the first year. The roses and leaucanthemums had just finished flowering and that was it for the rest of the year. I should also add, there was nothing prior to the rose display either.
As each year passed I was slowly but surely getting more colour introduced and a greater succession of interest; tulips were one of the first introductions that bridged the gap.
Even in mid-October, the border is still providing a colourful display. Ornamental grasses playing a huge part for autumnal interest, lasting well into the winter months. The tall, bleached erect stems of Calamagrostis 'Karl Foerster' is a really fab plant and one I would use more often if the conditions allowed.
