(Other gentians open at the top.) The plant grows 1 to 3 feet in height and has sessile (no petiole) leaves that are opposite, entire, lanceolate, hairless,…

Balsam Mountain Gentian
Gentiana sp. The last days of August… Today, I was pleasantly surprised to find this tall species of Gentian growing in the meadows of Grayson Highland State Park. At first I thought it was Bottle Gentian, but the bright green color of the leaves, the large size of the flowers, and the high elevation locale led…
Stiff Gentian
Gentianella quinquefolia Just when I thought that the growing season had advanced to the point where no new flowers would come my way, surprise–here comes Stiff Gentian! Members of the Gentian family offer great late-season color, especially in the realm of blues, purples, and violets. Stiff gentian differs in a few significant ways from the other gentian species found…

Great Blue Lobelia
Lobelia siphilitica It is a late summer treat to see great blue lobelia in full bloom, often alongside the fabulously red cardinal flower. Sometimes called “blue cardinal flower”, great blue lobelia resembles red cardinal flower, (Lobelia cardinalis), in stature, habitat, and structure. Both of these plants are tall wetland species with colorful flowers borne on terminal racemes. Their…
Blue Vervain
Verbena hastata No need to bend over to see this tall beauty! Blue vervain grows 2 to 5 feet tall!

The flowers on…

Blue Mist Flower or Wild Ageratum
Conoclinium coelestinum Until today, I always thought of ageratum as a low-growing garden annual that you could buy readily in any garden center– but I never knew it was also a native wildflower! I recently found a colony of these plants growing along the side of a shallow pond in Blacksburg, VA. The plants were…
Chicory
Cichorium intybus Chicory, blue sailors, wild succory, coffeeweed, or cornflower…whatever you want to call it–how can you not LOVE the bright blue flowers of this tough little wildflower? In a summer field, chicory stands out because of its tall, rigid stems that almost appear woody. Here and there along the stem appear aster-like flowers in…

Scutellaria serrata Here’s a beautiful wildflower! The dainty flowers are two shades of purple and they are held high above the simple and attractive foliage. The morphology of the flower is interesting at each stage of development–from new buds to maturity. Just take a look at some of the photos below… Skullcaps are in the Mint…
Wild Comfrey
Cynoglossum virginianum The genus name for Wild Comfrey, Cynoglossum, can be translated as “dog’s tongue”. The name refers to the shape of the plant’s leaves, which are ovate to narrowly elliptical, smooth on the edges, and 2 to 8 inches long —just like a dog’s tongue! In fact, another common name for this native plant…

Quaker Ladies
Houstonia caerulea Everyone has seen bluets before, but did you know that the real name for them is Quaker Ladies? This is a native plant that goes unnoticed most of the time, because it is so small and low-growing. That is, until springtime. That is when Quaker Ladies send up their slender flower stalks and the…
Dwarf Larkspur
Delphinium tricorne Sometimes in blue, sometimes in white, and sometimes in both blue and white, dwarf larkspur can be found blooming right now in local woodlands. This plant is among the showiest of the spring wildflowers, and it is a great reason to schedule some time outdoors soon. Before dwarf larkspur comes into bloom, the first cluster of basal leaves are…

Tended by invisible hands, miniature gardens are bursting from the forest floor with color and promise. Here’s just one example, Dwarf Crested Iris! As the name implies, Dwarf Crested…
Wild Blue Phlox
Phlox divaricata My wooded yard is full of this tall, lovely wildflower! Although it is called blue phlox, the flowers sometimes appear pink or purple. Look closely and you will see that the outer edge of the flower petal is notched outward. The stem of this plant is hairy and slightly sticky; the leaves at…
Great-spurred Violet
Viola rostrata In general, I think violets are hard to identify with real certainty, but thankfully this one has a few distinctive characteristics, starting with an extremely long “spur” on the back of the flower. There are also “toothed stipules”, or very small serrated leaflets in the space where the leaf meets the stem (see photo at right)….
Virginia Bluebells
Mertensia virginica Virginia bluebells are also called Virginia cowslip, or Roanoke bells. I first spotted them here in Blacksburg in a friend’s yard, but soon learned that this native wildflower grows extensively along the banks of streams and rivers in this part of Virginia, making it a riparian species. Last year I saw them growing…
Gill-Over-The-Ground vs. Purple Dead Nettle
Glechoma hederacea I’m going to take a break from weeding my garden to recognize two very fast-spreading members of the mint family (Laminaceae). The first one gets the Award for being “Most Insufferable”. Gill-over-the-ground (AKA Ground Ivy or Creeping Charlie) is a low-growing mint with a creeping habit. Like many garden weeds, it tolerates the…
