To pass the afternoon, we sat quietly along the edge of a pond created recently by North American Beavers (Castor canadensis). They first constructed their dam on this small stream about five years ago. Since then, a flourishing wetland has become established. Have a look.
Vegetation surrounding the inundated floodplain helps sequester nutrients and sediments to purify the water while also providing excellent wildlife habitat.The beaver lodge was built among shrubs growing in shallow water in the middle of the pond.Woolgrass (Scirpus cyperinus) is a bulrush that thrives as an emergent and as a terrestrial plant in moist soils bordering the pond.A male Common Whitetail dragonfly keeping watch over his territory.A Twelve-spotted Skimmer perched on Soft Rush.A Blue Dasher dragonfly seizing a Fall Field Cricket (Gryllus pennsylvanicus).A Spicebush Swallowtail visiting a Cardinal Flower.A Green Heron looking for small fish, crayfish, frogs, and tadpoles.The Green Heron stalking potential prey.A Wood Duck feeding on the tiny floating plant known as Lesser Duckweed (Lemna minor).A Least Sandpiper poking at small invertebrates along the muddy edge of the beaver pond.A Solitary Sandpiper.A Solitary Sandpiper testing the waters for proper feeding depth.A Pectoral Sandpiper searches for its next morsel of sustenance.The Sora (Porzana carolina) is a seldom seen rail of marshlands including those created by North American Beavers. Common Cattails, sedges, and rushes provide these chicken-shaped wetland birds with nesting and loafing cover.
Isn’t that amazing? North American Beavers build and maintain what human engineers struggle to master—dams and ponds that reduce pollution, allow fish passage, and support self-sustaining ecosystems. Want to clean up the streams and floodplains of your local watershed? Let the beavers do the job!
It may be one of the most treasured plants among native landscape gardeners. The Cardinal Flower (Lobelia cardinalis) blooms in August each year with a startling blaze of red color that, believe it or not, will sometimes be overlooked in the wild.
Cardinal Flower is most often found in wet soil along forested bodies of water. The blooms of this shade-loving species may go unnoticed until rays of sunshine penetrate the canopy to strike their brilliant red petals.
The Cardinal Flower grows in wetlands as well as in a variety of moist soils along streams, rivers, lakes, and ponds. Shady locations with short periods of bright sun each day seem to be favored for an abundance of color.

To its right is its close relative, Great Lobelia, a plant sometimes known as Great Blue Lobelia or Blue Cardinal Flower.Cardinal Flower in a wet bottomland woods.The Cardinal Flower can find favorable growing conditions along stream, river, and lake shores. Even though they are perennial plants, their presence along such waters often seems temporary. Changing conditions cause them to suddenly disappear from known locations, then sometimes reappear at the same place or elsewhere nearby. Some of this phenomenon may be due to the fact that stressed plants can fail to bloom, so they easily escape notice. When producing flowers during favorable years, the plants seem to mysteriously return.Cardinal Flowers along a wave-swept shoreline light up the greenery of erosion-controlling riparian vegetation with glowing red color.
The Cardinal Flower can be an ideal plant for attracting hummingbirds, bees, butterflies, and other late-summer pollinators. It grows well in damp ground, especially in rain gardens and along the edges streams, garden ponds, and stormwater retention pools.

REMEMBER the CARDINAL RULE…
Cardinal Flower plants are available at many nurseries that carry native species of garden and/or pond plants. Numerous online suppliers offer seed for growing your own Cardinal Flowers. Some sell potted plants as well. A new option is to grow Cardinal Flowers from tissue cultures. Tissue-cultured plants are raised in laboratory media, so the pitfalls of disease and hitchhikers like invasive insects and snails are eliminated. These plants are available through the aquarium trade from most chain pet stores. Though meant to be planted as submerged aquatics in fish tank substrate, we’ve reared the tissue-cultured stock indoors as emergent plants in sandy soil and shallow water through the winter and early spring. When it warms up, we transplant them into the edges of the outdoor ponds to naturalize. As a habit, we always grow some Cardinal Flower plants in the fish tanks to take up the nitrates in the water and to provide a continuous supply of cuttings for starting more emergent stock for outdoor use.

Cuttings from this plant will be used to grow emergent specimens in shallow water for transplanting outdoors around the garden pond.A Cardinal Flower grown from an aquarium store tissue culture blooms in the pond at susquehannawildlife.net headquarters.Grown as an emergent, Cardinal Flower may bloom very late in the season. This tissue-cultured specimen in the headquarters pond was photographed in early November, 2022.
