Laurel Heaven

The stand of mountain laurel that I wrote about last time is now at glorious peak bloom. My wrist is healing well, so I was able to manage the D750 with the kit lens (24-120mm) to get a few pictures.

If you read about mountain laurel in just about any guidebook you’ll probably come across a phrase like “impenetrable thicket”, describing how they grow. Apparently in the southern Appalachian mountains these thickets are known as “laurel hells.”  I hope to find one someday, but in the meantime I’m enjoying a local laurel heaven.  Hope you are, too!

 

Other common names for Kalmia latifolia include spoonwood, spoon-hunt, calico-bush, big-leaved ivy, ivybush, red-stemmed ivy, clamoun, little laurel, small laurel, wood laurel, poison-laurel, sheepsbane, lambkill, and wocky*.

Mountain Laurel and Sheep Laurel

Just was I was on a roll getting this blog going again, I had to go and break my wrist.  No more photography for awhile, but I wanted to let you know about this great stand of mountain laurel.  Two weeks ago they were budding up, so I expect they’ll be open by now.

 

 

 

The plants are on the Cabin John Trail, roughly midway between Bradley Boulevard and River Road. There’s a trail marker there, at the side trail that goes to Cindy Lane, and the stand starts just to the south of that and goes on for a few tenths of a mile. There must have been thousands of mountain laurels. Not all were in bud, of course, but a lot were, so it should be a good show.

Mountain laurel (Kalmia latifolia) is a medium-sized evergreen shrub in the heath and heather family.  Like other ericaceous plants, it prefers acidic soils that are moist and well-drained. It ranges from the Gulf of Mexico coast north all the way to Maine, and westward a little ways past the Appalachian Mountains (further west in the South).  In Maryland it can be found in every county.

If you’re exploring this segment of the Cabin John Trail, keep your eyes open for pinxterbloom azaleas (Rhododendron periclymenoides). They grow in the same area as the mountain laurels, mostly along the banks of the creek. I counted at least twenty-one of them blooming on April 27th this year. They’re almost certainly done by now.

One other species of Kalmia is found growing in Maryland: K. angustifolia, or sheep laurel.  The Coastal Plain of Maryland is almost as far south as it grows; it’s found more frequently as you go northeast, all the way into Maine and beyond, well into Québec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland (where I took this picture, in 2017).

 

Lucky Day

After a few years of trying, I finally caught trailing arbutus in bloom on Friday, April 13.

This is an uncommon species. Although it has a wide range (most of the US east of the Mississippi, and the upper Midwest ) it isn’t found in large numbers anywhere.


That might be because of its rather specialized growing requirements: moist but well-drained acidic soils. It likes undisturbed open woodlands, especially rocky slopes, where leaf litter doesn’t collect. Look for it whenever you see other species in the Ericaceae, like mountain laurel, blueberry and deerberry, and spotted wintergreen.

Many authors recommend against trying to grow trailing arbutus in the home garden: it is difficult to propagate, leading to poaching concerns; also, it is suspected that, like other species in the Ericaceae, it might have specific mycorrhizal associations without which it simply cannot grow.

 

It’s certainly a belly flower, but also  technically a shrub.  Epigaea repens stays low, the tough evergreen leaves lying flat along semi-woody stems that creep over the ground.

 

 

The plants are polygamo-dioecious, meaning that any given plant has two types of flowers: staminate and perfect, or pistillate and perfect. (See this post about maples for a more complete description of these terms.)

 

Also known as mayflower, this species has a delightful scent, but you have to get your schnoz right up in there to smell it.

Trailing arbutus is endangered in Florida and exploitably vulnerable in New York. It’s the state flower of Massachusetts and the provincial flower of Nova Scotia.

These pink-flowering and white-flowering specimens were blooming along a bank under mountain laurel (Kalmia latifolia) on Sugarloaf mountain.

Just Around the Corner

A few days ago a friend reported seeing spring beauty (Claytonia virginica) blooming on the Billy Goat C trail. Damn, that’s early!  Think I’ll head out tomorrow and have a look, because it has been literally months since I last photographed a wildflower.

Except for this one: trailing arbutus (Epigaea repens), a low-growing evergreen in the Ericaceae. Please forgive the picture quality; it’s a quick iPhone snapshot to remind me to go back and look for it again, because it’s already budding up, and I’ve never seen one in bloom. If I manage to catch it flowering I will of course be writing about it here.

Nerd moment: I just realized it’s time to start my 2018 spreadsheet.

Wildflowers Along Newfoundland’s Skerwink Trail

After two days of puffin hunting, I realized that it was fruitless to try to photograph them much before sundown, so early on day three I drove south to Skerwink Head, where a 5.3 kilometer loop trail takes you along coastal cliffs, through boreal forest and bog. Here I found flowering plant species that weren’t in the Bonavista area.

Of course balsam fir (Abies balsamea; Pinaceae) isn’t a flowering plant, but since it is the predominant species in this region, I wanted to show it. I have some sort of mental block when it comes to conifers and can never remember how to tell them apart. One clue, though, is that fir cones always stand up. Also, there’s this handy mnemonic: “Flat, friendly fir needles. Sharp, spiny spruce needles.”*

Sheep laurel (Kalmia angustifolia; Ericaceae) is a northern relative of mountain laurel (Kalmia latifolia); the former ranges from southern Virginia north into Newfoundland and Labrador, while the latter ranges from the Florida panhandle north through Maine. In Maryland sheep laurel is found mostly in the Coastal Plain.

Seven-angle pipewort (Eriocaulon aquaticum; Eriocaulaceae) is an aquatic plant that ranges from South Carolina north into Newfoundland and Labrador. In Maryland it’s listed S1/endangered and is a plant of the Coastal Plain.

 

Another aquatic plant, Dortmann’s cardinalflower (Lobelia dortmanna; Campanulaceae) is native to northern North America and Europe. In the US it can be found as far south as New Jersey. I don’t believe it’s found in Maryland, but there are conflicting accounts.

Twinflower (Linnaea borealis; Caprifoliaceae) is circumboreal, as the specific epithet suggests. In the US it’s found in New England, the upper Mid-West, and southwards in the Rocky Mountains. Some sources list in Maryland, but Maryland Biodiversity Project has no records; if it’s here, it would likely be in the far western part of the state, in the Allegheny Plateau.


Dwarf cornel (also Swedish bunchberry, Lapland cornel, and many others; Cornus suecica; Cornaceae) is a circumpolar species. In North America the furthest south it gets is Nova Scotia or Quebec. A closely related species, also called bunchberry (C. canadensis), ranges much further south; in Maryland that species is found only in Garret County and is listed S1/highly state rare. In areas where both species are found, they can be distinguished by leaf venation.

There’s something really special about glancing into the dim understory and spotting an orchid. Dactylorhiza viridis (frog orchid, also placed in the genus Coeloglossum, and formerly in Platanthera) is wide-ranging in the Northern hemisphere. I saw it in Iceland and once in Maryland, where it’s listed S1/endangered.


Moneses uniflora
(Ericaceae) has many common names, including one-flower wintergreen, one-flower shinleaf, and simple delight. It’s found in much of the northern part of the northern hemisphere, including New England, the upper Mid-West, and the Rocky Mountains. In Maryland look for the closely related striped wintergreen.

Garden lupine or bigleaf lupine (Lupinus polyphyllus; Fabaceae) ranges from Minnesota east and north into Newfoundland (but not Labrador), and also in the western US and Canada. Various accounts claim it is native to this western region, but none say that it’s alien to the east, so I’m not sure what its “native’ status is in Newfoundland. BONAP and USDA PLANTS Database show it in Maryland, but Maryland Biodiversity Project has no records for it.
