Most astilbe plumes tend towards cool pink, lavender and white shades, with a few reds sprinkled in. Warmer peachy pinks, like Peach Blossom, are recent developments and fine companions for gardens that lean towards the sunny side of the color wheel. Puffy flower heads are held tall, well above the serrated foliage. Big 5-8 eye clumps make the most of your gardening time with plants that settle in and get growing quickly.
