Pink azalea (Rhododendron prinophyllum) is found on acidic cherty soils on the dry ridge tops at LaRue Pine Hills. They are almost always at peak bloom on Mother's day weekend in May. Photo by Penny Stritch.
The days of late summer and early autumn bring the yellow blooms of the aster family into prominence in the upland forests at LaRue Pine Hills. Woodland Sunflower (Helianthus divaricatus) is a commonly encountered autumn wildflower. Photo by Larry Allain, USGS PLANTS Database.
Only when the yellow flowers of bladderwort (Utricularia vulgaris) appear above the surface of the swamp waters will you know that this carnivorous plant is part of the swamp ecosystem. The purple appearing plants on the surface of the water are Mexican mosquito fern (Azolla mexicana). The aquatic green plants floating on the surface are several species of duckweed (Lemna spp.), the United States' smallest flowering plant Columbian watermeal (Wolffia columbiana), and common duckmeat (Spirodela polyrrhiza).

The views from atop the Pine Hills give the observer an opportunity to see the LaRue swamps below. These swamps are derived from meander bends of a previous route of the Big Muddy river. Photo Larry Stritch.
LaRue Pine Hill
Forest: Shawnee National Forest
District: Mississippi Bluffs Ranger District
Description: LaRue Pine Hills’ unique characteristics dictate and support a rich biodiversity. It covers about 4.5 square miles (3,547 acres) and contains 14 natural communities including forests, swamps, ponds, wetlands, hill prairie, limestone barrens, and striking geologic features. LaRue Pine Hills supports nearly 1,200 species of vascular plants and as such is one of the country’s most diverse areas within an area 4.5 square miles.
Viewing Information: Throughout the year, numerous wildflowers can be seen in this beautiful area. Spring ephemerals including spring beauty (Claytonia virginica), cleft phlox (Phlox bifida), celandine poppy (Stylophorum diphyllum), Virginia bluebells (Mertensia virginica), dutchman’s breeches (Dicentra cucullaria), dog-tooth violet (Erythronium americanum), and sessile trillium (Trillium sessile) are commonly encountered on the rich mesic slopes. Spring flowering shrubs are encountered sporadically across the landscape. Several shrubs of note are Pink Azalea (Rhododendron prinophyllum), rusty nannyberry (Viburnum rufidulum) and in the autumn members of the Aster family are common across the landscape. Autumn wildflowers such as showy goldenrod (Solidago speciosa), blue-stem goldenrod (Solidago caesia), woodland sunflower (Helianthus divaricatus), joe-pye-weed (Eupatorium maculatum) and various asters (Aster cordifolius, A. divaricatus, and Aster azureus) will delight visitors into late October.
Safety First: Be prepared in spring, summer and autumn for rapid changes in weather as thunderstorms may develop rapidly. Timber rattlesnakes, copperheads and water moccasins are present so please stay on trails. None of these snakes tend to be aggressive but they will defend themselves if stepped on or threatened at close range. Just watch the ground as you walk and you should not have any problems. The lower bluff road is closed seasonally to allow for undisturbed movement of snakes from the swamps into the uplands in autumn and from the uplands to the swamps in spring. Temperatures in the summer can be high 90 to 100 F. Bring plenty of sunscreen and insect repellant. Poison ivy is common; remember leaves of three let it be.
