 Angel Series Hydrangea Have you seen the large, elegant leaves of elephant ears or bananas used in tropical gardens? You might be surprised to learn that many of the heat lovers are also muck lovers. Even though many of these plants will grow in good garden soil, they really get spectacular in soggy soil.
If you think you cannot grow water-loving plants, reconsider your options. You can build yourself a boggy area in your own backyard. Construct your bog near a downspout or rain barrel, letting it seep into your mucky mire. Don't confuse this with a rain garden. We will talk about that another time. One caveat, do not locate it near the house foundation. Slope it away from your home. Dig out an area wide and long enough to accommodate the plants you would like to grow. Dig it about a foot deep. Line it with a vinyl pond liner but make sure the vinyl does not slope up the sides. Punch a few small holes in the bottom. You want the water to be able to soak into the surrounding garden area so that it does not become stagnant or a mosquito breeding area. If you live in colder zones, you will have to dig many of these plants and winter them indoors. On the other hand, you can treat them as annuals and replace them every year. You can use water-loving plants to stop erosion and runoff. Elephant ear (both Alocasia and Colocasia) come in traditional huge green, black ('Black Magic'), black and green (Colocasia esculenta 'Illustris,' one of my favorites),  Japanese Iris and Alocasia 'Hilo Beauty' which wears leaves camouflaged in green, lime, and beige. These plant roots grab the water to make their spectacular leaves. Cannas love bogs and reward you with many flowers on tall strong stalks. Ligularia, also usually grown in garden soil, will be much happier in a shady bog. The native Louisiana iris, or the Japanese iris (Iris ensata), and yellow flag iris (Iris pseudacorus) make beautiful clumps or sweeps of flowers in wet areas. Any water overflow slowly percolates out the sides of the bog and into the soil, where it is naturally filtered and cleaned. Amend the soil with compost in this overflow area and locate hydrangeas like 'Penny Mac', or a new beauty in the Halo(tm) series, Angel Lace(tm), or the native 'Annabelle', where they will benefit from the extra moisture.  Illustris Primroses, variegated holly fern (Arachniodes simplicior variegata), astilbe, and toad lilies (Tricyrtis) can edge the boggy area in part shade. Site a cut leaf Japanese maple so that it can cascade to the side. They all thrive on damp, well-drained soil, kept moist but not wet. Think of it. No need to drag a hose. They can water themselves. Rushes grow wild in many areas. A highly ornamental plant, the Great Spiral Rush (Juncus effusus) can be found growing in wet, mucky soil. Another native, Cephalanthus occidentalis, or Button Bush, thrives at water's edge along lakes and streams. 'Sputnik' is a selection aptly named for its very large flowers. Its nectar rich blooms, large for a buttonbush, benefit butterflies and bees. Try something new but do be aware of your state's noxious weed list. Our waterways are precious. Do not plant anything that might get loose in your environment. Check out plants at the USDA website, http://plants.usda.gov/java/noxiousDriver. Go for a bog, but be smart with your choices.
