When creating your garden, you should remember to think in three dimensions. Just as you can create a dramatic effect with the combination of colors, you can also compose with different heights, and these blooms over two feet will lift your garden far off the ground.
The globe thistle, for example, is a versatile flower when it comes to placement. While smaller types form a lovely bouquet, the taller of the species are ideal as background plants and at the edges of gardens. Like an antique frame around a modern painting, these tall perennials define the borders of your garden, and bring out the color and breadth of your other flowers.
The perennials on this page come in a variety of colors, and require varying degrees of exposure to the sun. Consider how much sky is available in your garden, and then select the flowers that will create a tapestry in your yard.
