The astilbe is a popular flower promoted by many garden centers for shade gardens. However, without an ample supply of moisture, these late spring through summer flowers will never reach their glorious potential. Astilbes are a slow growing perennial, so unless you’re planting a large group and wish to save money, start with potted plants. In spite of the astilbe’s need for abundant moisture (dry spells will induce dormancy), some drainage during the winter months is necessary. Astilbes are... heavy feeders, so regular soil amendment and fertilizer is important.

The bearded iris has enjoyed the limelight in many gardens, but the smaller Siberian iris rarely succumbs to the iris borer or leaf spot disease that claims many bearded iris specimens. To add to its low-care appeal, Siberian irises rarely require division. Your plants may take a few years to get established, so don’t remove them if they don’t seem to take off at first.

The white or pink flowers of the chelone make a welcome appearance in August and September in the shady garden, when not much else is going on. The plants prefer dappled shade to dense shade, which can cause weak stems that flop over. Turtleheads appreciate humus-rich mulch in addition to very moist soil.

Whether your soggy spot lies in sun or shade, you can make it a focal point by choosing one or more of these flowering bog garden specimens.
