  • Coltsfoot (Tussilago farfara)

    Coltsfoot is one of our earlier spring flowers; these were blooming on the grounds of the Pittsburgh Zoo, Highland Park, in early April. The cheery and shaggy yellow flower heads top a short stalk that pops straight out of the ground; there are no leaves until later on. The plant’s favorite habitat seems to be a damp hillside at the  edge of the woods, often beside a street or highway. Coltsfoot was, as its generic name suggests, a popular cough remedy; but it has been known to cause serious liver damage, so it’s not as popular as it used to be.

    Gray describes the genus and the species:

    TUSSILÀGO [Tourn.] L. COLTSFOOT. Head many-flowered; ray-flowers in several rows, narrowly ligulate, pistillate, fertile; disk-flowers with undivided style, sterile. Involucre nearly simple. Receptacle flat. Achenes slender-cylindric or prismatic; pappus copious, soft, and capillary. — Low perennial, with horizontal creeping rootstocks, sending up scaly scapes in early spring, bearing a single head, and producing rounded heart-shaped angled or toothed leaves later in the season, woolly when young. Flowers yellow. (Name from tussis, a cough, for which the plant is a reputed remedy.)

    T. farfara L. — Wet places and along brooks, e. Que. to Pa., O.,and Minn. (Nat. from Eu.)

    –

    Frederic William Stack gives us this description in Wild Flowers Every Child Should Know:

    COLTSFOOT. COUGHWORT.

    Tussilago Farfara. Thistle Family.

    This is the same Coltsfoot that our grandmothers used to gather and dry and hang in the garret along with their Boneset, Catnip, Goldthread, and a various assortment of garden herbs. Coltsfoot was considerably used at one time as a family remedy for coughs and colds, and many a steaming cupful has been sipped by country people for this purpose. Its Latin name, an old one used by Pliny, is derived from tussis, a cough, and ago, alluding to the medicinal use of the leaves. The ancients smoked the leaves of Coltsfoot for relief in cases of asthma. Its fresh juice has been used for affections of the skin, and in Germany the dried leaves are said to be used as a substitute for smoking tobacco. The flowers of the Coltsfoot look something like those of an imperfectly developed, or half-opened Dandelion, but where the flower heads of the Dandelion are slightly tufted or raised toward the centre, those of the Coltsfoot are cupped or hollowed, more like an Aster, with a finely fringed edge. The rather large, solitary flower is borne on a thick, hollow, light green stem, rising direct from the long, slender, creeping perennial root from four to eighteen inches in height. It is usually stained with red and is covered with numerous scalelike and alternating leaflets. The light yellow flower head is of a lighter shade than that of the Dandelion, and is set in a deep, leafy, thimble-shaped green cup. It is composed of many ray and disc florets — an arrangement fully explained in the description of the Asters. The ray florets are fringe-like, and the small disc florets are five-parted. They have an agreeable odour, and as they fade, they turn to red-brown.

  • Skunk Cabbage (Symplocarpus foetidus)

    Skunk Cabbage is one of the earliest flowers to bloom; it can come out as early as February, before the leaves have appeared at all. The curious inflorescence at once marks it as a member of the Arum family, which also includes Jack-in-the-Pulpits, as well as the callas and anthuriums in florists’ shops. This plant was photographed in early April, by which time the leaves had emerged; they smell awful if you crush them. It likes wet ground, and this one was blooming in a muddy low spot next to the Squaw Run in Fox Chapel.

    Gray describes the genus and the species:

    SYMPLOCÁRPUS Salisb. SKUNK CABBAGE. Stamens 4, opposite the sepals, with at length rather slender filaments; anthers extrorse, 2-celled, opening lengthwise. Style 4-angled and awl-shaped; stigma small. Ovule solitary, suspended, anatropous. Fruit a globular or ovoid mass, composed of the enlarged and spongy spadix, inclosing the spherical seeds just beneath the surface, which is roughened with the persistent fleshy sepals and pyramidal styles.— Perennial herb, with a strong odor like that of the skunk, and also somewhat alliaceous; a very thick rootstock, and a cluster of very large and broad entire veiny leaves, preceded in earliest spring by the nearly sessile spathes, which barely rise out of the ground. (Name from symploke, connection, and karpos, fruit, in allusion to the coalescence of the ovaries into a compound fruit.)

    S. foétidus (L.) Nutt. Leaves ovate, cordate, becoming 3-6 dm. long, short-petioled; spathe spotted and striped with purple and yellowish-green, ovate, incurved. (Spathyema Raf.)—Bogs and moist grounds, N. S. to N. C, w. to Ont., Minn., and Ia.

  • Hairy Bittercress (Cardamine hirsuta)

    Depending on your point of view, this is either an invasive weed or a cheery harbinger of spring. It comes from Europe, and it makes itself at home in our lawns, where it politely refuses to exceed the height of the grass around it. There are people who eat it as a salad herb, so it can’t be all bad. It’s one of the first things to bloom in the spring, appearing along with the crocuses and persisting through daffodil season. This patch was blooming in a lawn in Beechview in early April.

    Gray describes the genus and the species:

    CARDÂMINE [Tourn.] L. Bitter Cress. Pod linear, flattened, usually opening elastically from the base; the valves nerveless and veinlees, or nearly so; placentae and partition thick. Seeds in a single row in each cell, wingless; the funiculus slender. Cotyledons accumbent, flattened, equal or nearly so, petiolate.— Mostly glabrous perennials, leafy-stemmed, growing along watercourses and in wet places. Flowers white or purple. (A Greek name, used by Dioscorides for some cress, from its cordial or cardiacal qualities.)

    Root mostly biennial or annual; leaves pinnately 5-11-foliolate, flowers small, white.

    Stamens 4; leaflets strigose-hispid upon the upper surface.

    С. hirsuta L. Leaves chiefly radical, with short and broad leaflets, but those on the erect stem reduced and with narrow leaflets; pods erect, on ascending or appressed pedicels. — Moist places, s. l’a. to N. C, and “Mich.” (Eu.) Perhaps introduced. A doubtful specimen from w. Mass. (Miss Vail).

  • Groundsel (Senecio vulgaris)

    This ubiquitous weed is found in temperate latitudes throughout the world. The tight little flower heads never open up any wider than what you see here. These plants, growing on a sunny and recently disturbed bank in Beechview, were among the very earliest flowers to bloom in the spring; this picture, in fact, was taken on March 20, the first day of spring.

    Gray’s description of the genus and species follows, but it does not describe the plants in the photograph very well. The on-line Flora of North America remarks that the plants may be “sparsely tomentose when young,” as these plants were. And although Gray gives “July-Sept” as the flowering period, the Flora of North America says “flowering early spring.” In fact these can also be seen very late in the fall, and almost any time in between. The plant blooms very quickly from seed, and seedlings can overwinter; and it seems to present very different habits depending on the time of year.

    SENECIO [Tourn.] L. Groundsel. Ragwort. Squaw-weed. Heads many-flowered; rays pistillate or none; involucre cylindrical to bellshaped, simple or with a few bractlets at the base, the bracts erect-connivent. Receptacle flat, naked. Pappus of numerous very soft and capillary bristles.— Ours herbs, with alternate leaves and solitary or corymbed heads. Flowers chiefly yellow. (Name from senex, an old man, alluding to the hoariness of many species, or to the white hairs of the pappus.)

    Annuals (rarely becoming biennial); stems leafy to the Inflorescence; heads medium-sized, 1 сш. or less high during anthesis.

    S. vulgàris L. (Common Groundsel.) Low annual, 1-6 dm. high. corymbosely branched, glabrate, leafy to the inflorescence; leaves pinnatifid and toothed, 1-8 cm. long, 0.6-3 cm. broad; calyculate bracts (bracteoles) of the involucre distinctly black-tipped; rays none; achenes hirtellous. — Waste grounds, common. July-Sept. (Nat. from Eu.)

  • Great Lobelia (Lobelia siphilitica)

    Sometimes called “Blue Cardinal Flower” because of its strong resemblance to its close relative the Cardinal Flower, L. cardinalis, with which this species apparently hybridizes. The unattractive species name comes from an old belief that it was a treatment for syphilis. The Plant Fact Sheet (PDF) from the Natural Resources Conservation Service adds that “The Meskwaki ground up the roots of this plant and used it as an anti-divorce remedy.” What America needs today is more ground-up Lobelia siphilitica roots.

    The flowers are variable in color: some are solid pale blue, some darker blue, and some—as here—strongly bicolored. A white form is found occasionally.

    Like the Cardinal Flower, this Lobelia likes damp situations; this one grew on the bank of a stream in Manor, where it was blooming in early October.

    Gray describes the genus and the species:

    LOBELIA [Plumier] L. Calyx 5-cleft, with a short tube. Corolla with a straight tube split down on the (apparently) upper side, somewhat 2-lipped; the upper lip of 2 rather erect lobes, the lower lip spreading and 3-cleft. Two of the anthers in our species bearded at the top. Pod 2-celled, many-seeded, opening at the top. — Flowers axillary or chiefly in bracted racemes ; in summer and early autumn. (Dedicated to Matthias de l’Obel, an early Flemish herbalist.)

    Flowers blue, or blue variegated with white.

    Flowers rather large (corolla-tube 1-1.3 cm. long), spicate-racemose; stem leafy, 0.3-1 m. high; perennial.

    Leaves ovate to lanceolate, numerous; lip of corolla glabrous.

    L. siphilitica L. (GREAT LOBELIA.) Somewhat hairy; leaves thin, acute at both ends, 0.5-1.5 dm. long, irregularly serrate; flowers nearly 2.6 cm. long, pediceled, longer than the leafy bracts; corolla light blue, rarely white; calyx hirsute, the sinuses with conspicuous deflexed auricles, the short tube hemispherical. — Low grounds, Me. to Ont. westw. and southw.; rare eastw.
