Rosea

There are a lot of pink wildflowers in the Maryland Piedmont. As with blue and purple, “pink” can vary quite a bit, from almost white to practically red.

Claytonia virginica (spring beauty; Portulacaeae)

One of our earliest ephemerals, blooming as early as late February after a warm winter, and lasting into May. In woodland soils almost everywhere. Usually white with a pink tint.

Mertensia virginica (Virginia bluebells; Boraginaceae)

Virginia bluebell buds start violet and turn pink before opening blue, except when the flowers are pure white or pure pink. I visit this stand every year just to make sure that the flowers really are all pink from start of bloom through senescence. They are.

Cercis canadensis (redbud; Fabaceae)

Around here, this understory tree usually blooms in April, when other trees are just starting to blush green. It’s a beautiful effect, though maybe not as stunning as…

 

Rhododendron periclymenoides (pinxter azalea; Ericaceae)

I don’t know that we have a more stunning native shrub than this. I’ve seen it in rocky, wet areas in Rachel Carson Conservation Park and Sugarloaf Mountain; it blooms in mid spring.

Silene caroliniana ssp. pensylvanica (wild pink; Caryophyllaceae)

Look for the flowers in early April to late May. These low-growing plants are often found in dry, rocky soils in open woodlands. There are several stands near Carderock.

 

Valeriana pauciflora (long-tube valerian, large-flower valerian; Valerianceae)

This delicate plant (S1/endangered) has an explosive inflorescence that usually opens in May. A great photo has always eluded me, despite hours and hours and hours of trying, because the plants bloom in the deep shade of dense woods. Shade is the bane of photographers. Maybe this year.

Hibiscus laevis (halberd-leaved rosemallow; Malvaceae)

Unlike the previous species, this one likes bright, sunny riverbanks. I love how it just glows in the light! Sometimes considered a forb and sometimes as a shrub, it’s a very tall plant with stems that get somewhat woody as the season progresses; but, like a forb, it dies back to the crown in autumn. Watch for it in early to mid summer. S3 in Maryland.

Hylodesmum nudiflorum (naked-flower tick trefoil; Fabaceae)

The tick trefoils can be tricky to identify, but this one stands out because the flowers are borne on leafless stems. The genus Desmodium was recently split, with some species placed in a new genus, Hylodesmum. According to the excellent gobotany site, species in the former as sun-loving, and species in the latter are shade-loving.

Desmodium paniculatum (panicled tick-trefoil; Fabaceae)

This one blooms in mid to late summer. It grows in moist to dry soils in sun to part shade, and does well in disturbed areas.

Lespedeza virginica (Fabaceae) Not seen as often as the alien invasive L. sericea, this species grows in dry areas, blooming in mid to late summer.

Asclepias incarnata (swamp milkweed; Apocynaceae)

If you want to spend hours being entertained by bees and butterflies, park yourself in front of a stand of milkweeds. I’ve seen them blooming in wet soils in sunny areas from late June to late August.

Persicaria amphibia (water smartweed; Polygonaceae)

Or, as I prefer to call it, DPP (damn pink persicaria). I’m fairly certain I’ve ID’d it correctly. Sometimes I’m not particularly attracted to a species until I sit and study it awhile and try to get good close-up pictures. So it was with this one. Click on the pic to see it larger. It’s pretty up close!

Sabatia angularis (rosepink; Gentianaceae)

I’ve only seen this plant once, in the shade of a small shrub even though it’s a sun-loving species. Watch for it in dry soils in open places. What a beautiful color.

So Very…

 

 

…Pink.

 

 

 

Not my favorite color.

 

 

 

 

But how can I not love this plant?

 

 

 

 

I wrote about pinxter azalea last year and don’t have anything to add.

 

 

 

 

I just wanted to post more pictures.

 

 

 

Rhododendron periclymenoides (Ericaceae) in Rachel Carson Conservation Park, April 27. Also look for them on the lower slopes of Sugarloaf Mountain.

Pink!

About ten days ago I read that the pinxters in Rachel Carson Conservation Park were in bud. A few days later, I went to have a look, but only a few were open. A few days after that, I went back and found them fully open, glorious splashes of pink blossoms among the pale green of new leaves on other trees.

There are thirty two native species of Rhododendron in the continental US. Seven of these occur in Maryland, mostly in the western counties or on the coastal plain. Three species are found in the piedmont. This species is a deciduous shrub growing to twelve feet tall (usually less). Like most ericaceous plants it prefers moist but well-drained acidic soils. At Rachel Carson you can find it near rock outcroppings and along the shore of the Hawlings River.

Supposedly pinxter is a fairly common plant, but I’ve never come across it before. I’ve read that it can be found on Sugarloaf Mountain. Guess I need to get back there soon. It’s listed as endangered in New Hampshire, expoitably vulnerable in New York, threatened in Ohio, and special concern in Rhode Island.

About the name…  According to  Cookies, Coleslaw, and Stoops: The Influence of Dutch on the North American Languages (Nicoline van der Sijs, Amersterdam University Press), the word “pinxter” comes from the word “pinkster”, the Dutch name for the religious festival known in English as Pentecost. You can read more about that here.

The more I looked at this flower, the more fascinated I became by its structure. Note the five stamens and one very long pistil per flower. In general, plants in the Ericaceae have twice as many stamens as petals (typically ten stamens and five petals, but not always). It took awhile but I finally read that the North American azaleas are an exception to this rule, having the same number of stamens as petals.
