 | Red Sentinel Astilbe. Glowing scarlet-red blooms, the Red Sentinel Astilbe (Astilbe japonica 'Red Sentinel') is one of the most outstanding red Astilbes! Deep forest-green leaves have mahogany-red stems which nicely complement the scarlet-red flowers. Red Sentinel is a real eye-catcher and brings in butterflies, bees, and hummingbirds! You’ll love the tall stems in your bouquets too! Lightly fragrant, the finely dissected foliage looks amazing all growing season long and acts as a lacy backdrop for the fluffy blooms!... - Red Sentinel Astilbe. |
