Dandelion and cat’s ear

DandelionFor our plant comparison we are going to look at dandelion (which most people know) and cat’s ear (a similar looking plant).  Beginning with this image of a lush dandelion (Taraxacum officinale), we can see lots of flower heads and a number of new heads forming, along with some closed heads which bloomed recently.  The dandelion could almost be an evergreen plant as it seems to grow year-round — at least whenever the temperature stays above freezing.  Let’s go through the dandelion’s life cycle and then check out the cat’s ear similarities and differences.

The dandelion’s flower head begins developing low in the center of the rosette of leaves.

DandelionGradually, the stem supporting the new flower head elongates until it rises well above the basal rosette.

DandelionThe dandelion’s hollow stem exudes a milky white substance (a type of latex) when broken.  After the flower head has blossomed, it closes in on itself . . .

Dandelion. . . converts those fertilized ovaries to seeds with wings . . .

Dandelion. . . and re-opens to create the familiar seed head which, once again, rises high above the basal rosette of leaves.

DandelionNote the fleshy stem supporting the seed head.  Here’s a closer view of that head with its symmetrical arrangement of the winged seeds.

DandelionAfter all the seeds have dispersed, what remains is the head’s receptacle.  It, too, has a lovely pattern.

DandelionHere is a final view of a dandelion plant.  You can see that most of its flowers have converted to seeds and/or have sent the new seeds on their way — to the irritation of people who want perfect lawns — and to the delight of herbalists and wild food foragers.

DandelionCat’s ear (Hypochoeris radicata) looks, on first glance, very much like the dandelion — especially when you see an area full of the plants.

Cat's earLet’s look more closely at this plant.  Here is its flower head . . .

Cat's ear. . . which, in isolation, looks like a dandelion flower head.  However, note its more wiry stem in the photo above and the next photo.

Cat's earYou can see a developing flower head in the background of the above photo.  This flower head looks similar to — and yet, different from — the dandelion flower head.  The difference is subtle.

As we stand back and look at the entire cat’s ear plant, we can see its flower heads rise on stems above the basal rosette of leaves.

Cat's earAlthough frequently a single flower head grows on a single stem (like the dandelion), it is just as likely the cat’s ear flower heads will appear on a branched stem.  In contrast, the dandelion’s single flower head will only appear by itself on an unbranched stem.  Along with the branched stems, this next photo shows the wiriness of the stems and the different looking unopened flower heads.

Cat's earAfter the flower heads have bloomed and become seeds, the heads re-open and spread their winged seeds — just like the dandelion.

Cat's earAnd this is where we can finally see some distinguishing characteristics between dandelion and cat’s ear.  The cat’s ear leaves are quite hairy while the dandelion leaves are smooth.  When you look closely at the shape of the leaves — by placing them side by side — you can see the dandelion is definitely sharply toothed, with its teeth pointing back toward the center of the plant.

Cat's ear and dandelionThose softly hairy leaves probably account for the common name given to cat’s ear.

Mountain (not Sessile) bellwort

Mountain bellwortThis is Mountain bellwort (Uvularia puberula) in the spring as it begins its growing season.  Here’s another flowering group. . .

Mountain bellwort

Let’s look more closely at the flower from the side . . .

Mountain bellwort. . .  and up into the flower.  Notice the shapes of the flower’s parts which are in sets of three.

Mountain bellwortBy mid-summer, the leaves have filled out and exhibit their alternating pattern along the stem.  You can see how similar this plant looks at this time to both Solomon’s seal (Polygonatum biflorum)  and False Solomon’s seal (Smilacina racemosa).

Mountain bellwortAahh, the Mountain bellwort is developing seed capsules!  You can see them in the above photo as well as the next photo.

Mountain bellwortNote the supporting structure for Mountain bellwort.  It has a single stem which forks into two stems with alternating leaves.  This is in contrast to Solomon’s seal (and False Solomon’s seal) which have a single stem of alternating leaves.

Let’s look more closely at the developing seed capsule.

Mountain bellwortVery interesting!  We can see how the seed capsule has three sides to it — just like the flower we saw in the spring.

Here’s a view of Mountain bellwort in the late summer / early fall when the leaf color begins to change from green to yellow.

Mountain bellwortAgain, we can see the branching pattern into two stalks from the single original stem.  Another view of the changing leaf color . . .

Mountain bellwortWhen we get close to this plant, we can see its seed capsule — now turning brown.

Mountain bellwortGradually, the yellow leaves also turn brown . . .

Mountain bellwortAnother view of the browning seed capsules. . .

Mountain bellwortThe seed capsules become brittle, open to release their seeds, and leave us a reminder of the previous spring’s flower.

Mountain bellwort

NOTE (11/25/13):  When I first discovered this plant in 2009, I thought it was Sessile bellwort (Uvularia sessilifolia).  I created this blog post in 2011 — describing what I then thought was Sessile bellwort.  Recently I re-read the plant’s description in several field guides and realized I had made an error.  This is Mountain bellwort (U. puberula) because it has fine (downy) hairs along the upper stems and at each leaf node.  The primary vein on the underside of the leaf also has fine hairs.  In contrast, Sessile bellwort has smooth, hairless stems and leaves.  In all other significant characteristics, the two plants look the same.  For some good photos of U. sessilifolia, visit the GoBotany site for New England wildflowers.
