Flower of the Day: Swamp Milkweed

Asclepias incarnata; Asclepiadaceae (milkweed family)

20140710-DSC_0076

A relative of yesterday’s FOTD.  A few characteristics differentiate the two. Note how the inflorescences in the picture above are held upright; the flower heads in common milkweed are often drooping.

Swamp milkweed tends to have rose pink flowers,20140710-DSC_0093

while common milkweed’s flowers are duskier.  And swamp milkweed has much narrower leaves, and the side veins join the midrib at an acute angle; in common milkweed, the side veins join the midrib at an almost ninety-degree angle:

Swamp milkweed is generally a foot or two shorter, not as fragrant, and likes a wetter habitat.  It would be a good plant for a consistently wet area of a garden, and will attract butterflies and hummingbirds.

Flower of the Day: Common Milkweed

Asclepias syriaca; Asclepiadaceae (milkweed family)

20140708-DSC_0138-2 Click on the picture below to enlarge and check out all the tiny moths! 20140708-DSC_0130 There are a whopping 72 native species of Asclepias found all over the US and Canada.  About a dozen of them are in the mid-Atlantic.

This is a big plant – up to six feet – with big leaves and big, showy, fragrant flowers heads, each of which can bear up to 120 individual flowers. It’s good for attracting butterflies but beware if you want it in your garden: because it spreads vigorously by roots, it’s considered a weed in much of its range. The USDA site has a great document about the plant, including interesting ethnobotanical history. Tomorrow, another type of milkweed.

Flower of the Day: Naked-Flowered Ticktrefoil

 Desmodium nudiflorum; Fabaceae (pea family)

20140708-DSC_0071

Plants in the Fabaceae are not my favorites, maybe because there are a lot of ugly, invasive aliens in that family.  But I did a double-take when I saw this one.  Isn’t it gorgeous?

Not like the typical scrawny sprawling messy plants that I’m seeing all over the area this time of year.  Naked-flowered ticktrefoil has one short stem of large compound leaves standing at about six inches , and another stem (leafless) bearing a panicle of flowers, about two feet up.

By the way the leaves in the picture above have dried sand from a nearby trail all over them.  I searched the immediate area for more (cleaner) plants to photograph, but this was the only one I could find.

There are 42 native species of ticktrefolis in the continental US.  This one ranges throughout the east and parts of the prairie midlands.  Apparently the name “ticktrefoil” derives from the fact that the seeds have tiny hooks, allowing them to stick like a tick to any passing animal; “trefoil” indicates a 3-leaved (or in this case, leaflet) plant.

Flower of the Day: Starry Campion

aka widowsfrill; Silene stellata; Caryophyllaceae (pink family)

20140702-DSC_0022   Starry campion is one of about 60 native and 18 alien species of Silene found in continental North America.  It ranges throughout the eastern US except Maine and Florida, though it is no longer found in Vermont and Rhode Island, is of special concern in Connecticut, and is threatened in Michigan. The plant stands about one to two feet tall, with a terminal panicle of blossoms (and sometimes a few more panicles along the upper stem).  It seems to like a variety of habitats, mostly in mesic soils on rocky slopes and along riverbanks, in light shade.

Another campion species I’ve found in the Carderock area is wild pink (Silene caroliniana), a low-growing plant of rocky places that blooms in early May:

This Just In!

We interrupt the “Flower of the Day” report to bring you this breaking news! Look what I found:

20140710-DSC_0188

OK, you’ll have to click on it to enlarge and see what’s in there.  And it doesn’t look like much – a bunch of small brown shoots standing a few inches above the leaf litter.

So what.  Big deal.

It is to me.  I’ve been waiting and waiting to see these in bloom.  Not long now!  Here’s a picture from mid-May:20140522-DSC_0002

Each leaf represents a single plant.

Know what it is yet?

Stay tuned…
