Dierama pulcherrimum, Blackbird. Full sun and in a warm, sheltered spot. Flowers June to August. Angel's fishing rod is perfect for introducing movement to a well-drained border in a sunny, sheltered site, or for overhanging water. Initially slow to establish, it looks particularly good with early autumn-flowering ornamental grasses. More: http://www.crocus.co.uk/plants/_/dierama-pulcherrimum/classid.2694/
Yes, you can create a garden like this! Just look at the shapes: sharp spires, round globes, soft spires, and a few oddballs. Pick flower shapes in the same color family (pinks and purples, here), throw in a few silver foliage plants, and plant closely together. It's that simple!
