Johnny-Jump-Up (Wild Pansy) Viola tricolor

Johnny-Jump-Up Violet (Wild Pansy) Viola tricolor. This soft stemmed plant is occasionally perennial, but in most zones is a self-seeding annual. An immigrant from the Mediterranean, this violet ranges in color from solid yellow to dark purple, the most common pattern being painted, purple lip with yellow stripes, the petals split between yellow and lavender. The elongated leaves, which have coarsely toothed margins, alternate along a squared, somewhat trailing stem.  The parent stock of commercial pansies, V tricolor produces viable seeds.  This wild stock bears 3/8” flowers on long stems, one at a time.  An uncommon visitor, this wild pansy escaped cultivation, and no occasionally blooms along forest margins, like Sunset Walk.  Not in books. 3/15/19-3/29/19; 20 no obs;

Johnson Grass

Johnson Grass, Sorghum halepense;  a very tall, jointed grass, rising from a thick rhizome, which produces a long, open spike of small seeds that remotely look like rice grains.  The long, broad leaves are often red toward the tips, growing part way up the flower spikes.  The thick, pithy stems are strongly jointed at nodes that may be 10″ apart.  Johnson Grass grows quickly, and the rhizomes easily break off when uprooted, allowing the grass to spread underground.  The rhizomes are edible, but not filling.  Johnson grass is not viable as a commercial food, for although the heads are heavy, the grains are small and tightly wrapped in chaff like bracts, and the leaves are poor in grazing quality.  Most common along partly shaded forest margins, or intermittent drainages.  New heads may be purple, opening to white flowers, which then ripen into small seeds.  Most of the seeds are eaten by birds, especially doves.

Rice Grass habit; fast growing stem grass with long, broad leaves, which produces long flower spikes bearing loose panicles of seeds that look remotely by rice.

Note; the tall, fast growing blades are often tipped in red

Note; long jointed flower spikes produce loose panicles of small white flowers

Violet, Missouri Violet

Missouri Violet (Wood Violet) Viola missouriensis. The only violet native to the ILC, this herbaceous perennial sprouts a cluster of deeply notched, cordate (heart-shaped) to arrow-shaped leaves.  Each flower stem produces a single, short-lived flower composed of two upright, light blue sepals, two lower, deep violet-blue petals, and a central, modified petal called a lip that sports three or four darker purple streaks.  The petal is modified into a small opening leading to a short, rounded nectar tube, just large enough for insects to insert their tongues.  Flowers convert to thin seed capsules full of tiny, dust like seeds.  Blooming season lasts 2-3 weeks.  Locally it is found only in shaded areas along forested trails where there is deeper, moist soil, but occasionally in yards, where it tolerates mowing.  Only found in low areas of MK trace, CC, SWk (378) 3/15/15-4/7/15; 3/10/16-4/1/16; 2/22/17-4/5/17; 3/15/18-4/2/18;

Vervain, Wright’s Vervain

Wright’s Vervain Verbena wrightii. A low growing, sprawling perennial consisting of tough stems radiating outward from a central tap root.  Opposite leaves are divided into three deeply pinnate lobes, which are wider than those of V hasata, Blue Vervain.  Thick, bushy, terminal spikes form a cone-shaped, tight cluster, or head, of light lavender-blue tube flowers.  Many flowers are open at the same time, creating a ring of lavender around the head, with green, unopened buds at the top.  The tubes are completely concealed in bracts, opening up to a corolla of 5 cleft petals, the bottom ‘lip’ petal being longer, and more deeply cleft.  This vervain prefers full sun, so is not found in shaded or forested areas, but is common everywhere else, specifically prairies, mowed areas, and west facing forest margins, where it forms dense clumps of bright blue flowers.  A favorite of butterflies and bees, Wright’s Vervain blooms early, goes dormant during summer heat, and resumes blooming in cooler fall weather.  PDU, CC (372) 4/2/15 – ; 3/10/16; 3/12/17- ; 3/22/18; 3/23/19; 3/25/20

Thistle, Texas Thistle

Texas Thistle Cirsium texanum.  A lanky thistle with long, ribbed, pithy stems, and dusty green, deeply pinnate leaves lined with only 4-5 spines per side of leaf.  This is the most common thistle on the ILC.  Rising from one pithy tap root, the main stem soon branches into multiple stems which are slightly grooved, but lack spines, like Nodding Thistle (C nutans).  Branching does not follow a symmetric pattern, and each long (6-10”) flower stalk bears only one elongated, slightly tapering flower-head, lined with prickly scales.    The lavender to rose-purple, hair-like petals are longer than Bull Thistle.  Not as robust or squat as Bull Thistle, Texas Thistle has shorter spines, does not have as sharp or thick of spines on stems, has much longer flower stalks, lacks spines on flower stalks, is a lighter lavender color, has longer hair-like petals, and has longer, more tapered buds.  However, it is only slightly less noxious.  (332) 4/28/15; 5/1/16, 4/17/17- ; 5/4/18; 4/28/19; 4/25/20

Spiny Sow Thistle

Spiny Sow Thistle Sonchus asper. An early (April) blooming annual, Sow Thistles begin as rosettes of deeply cut, thistle like leaves which look spiny, but are soft and harmless.  Leaves bleed a slightly bitter, but harmless milky sap when cut. The pinnate, clasping leaves, which have deep, rounded sinuses, are arranged in an alternating spiral around smooth, hollow stems.  The rosette of leaves stays low as long as the weather is cold, but quickly grows up when it warms, culminating in a compact clump of small, short lived, green buds, invariably coated with a white powder.  Stems can be trampled down, but continue to grow, arching back up and producing flowers.  Yellow ray flowers emerge from the tapering buds.  If cut back, the hollow stem quickly sends out new stalks.  The ray petals are squared at the ends, surrounding a yellow disk flower fuzzy with yellow anthers.  Flowers transform into coarse blow-balls of wind- blown achenes, and the plants wither soon after the plant goes to seed.  Common along partially shaded paths.  (222) 3/25/15-5/20/15; 3/10/16; 2/25/17- ; 2/8/19 – ; 20 not recrd;

Texas Yellow Star

Texas Yellow Star Lindheimera texana. A soft stemmed, fuzzy, if not bristly annual of medium height, the Yellow Star has opposite pairs of soft, clasping, fuzzy, light grey-green lanceolate leaves with smooth margins.  The single stems do not clump, and only weakly branch, going dormant by the time summer turns hot.  The 1” to 1.5” yellow-orange flowers are born in a loose, branching spray, opening one at a time, as a slightly bell-shaped 5 pointed, yellow “star” framed by 5 thick sepals.  Each petal is veined linearly, with a noticeable notch in the end.  Soft seed capsules split, spilling tiny brown-black seeds.  Preferring partial shade, it is found along forest margins of CC, PDU.

Texas Plume

Texas Plume (Standing Cedar) Ipomopsis rubra.  A biannual, the first year is spent as a low rosette of lacy, deeply cut compound pinnate, thread-like leaves.  The second year the tall (3-4’), pithy stem grows up out of the rosette, lined with increasingly smaller leaves, producing a spike like panicle of tubular, trumpet shaped, bright orange-red flowers with darker orange spots.  Unexpectedly, the 1” long by ½” wide flowers begin blooming from top down, small side branches producing dense clusters of orange flowers, .  Filamentous anthers and an even longer pistol protrude beyond the lip of the central nectar tube, which splits into five petals.  Seed capsules are tucked in the thread-like leaves, turning tan as they mature.  Plants grow readily from seed, especially in garden soil.  SWk.

Lettuce, Telegraph Lettuce

Telegraph Lettuce Lactuca floridana. A medium height (2-3’), hollow stalk with alternating, deeply lobed leaves with serrated edges.  Leaves look much like Prickly Lettuce, except they do not clasp the stem, lack thorns, and are much softer, and the plant blooms much later.  A multi-branched, terminal panicle, that becomes slightly tangled, has many small, aster like white flowers which open fully, converting to small blowballs.  Young leaves can be eaten like lettuce, before they turn bitter.  Found in shaded areas, along trails in forested areas or forest margins.  Disturbed areas, roadsides, MK, CC, CA.
