Sage; Texas Sage

Sage; Texas Sage, Leucophyllum frutescens.  This hardy, evergreen shrub from the Chihuahua desert sports light grey, rounded leaves, and bright purple tube flowers which are intensely fragrant.  A popular flowering hedge, Texas Sage tolerates trimming, is drought resistant, prefers full sun, and blooms when nothing else will.  The light grey, slightly fuzzy, oval leaves are attractive in their own right, and smell only slightly of sage.  The grey color and hairs give the shrub protection from both the hot sun, and cold desert nights.  The plant blooms irregularly, breaking out into full blooms several days after a rain, all the sage plants in an area blooming so vigorously that the shrub is covered with light purple tube flowers that open to a 5 petal corolla.  Flowers bud singly from the node of each leaf, covering new growths with blossoms.  Honey bees swarm to the heavily pungent flowers for the few days they are open.  This shrub will reach 10 – 15 feet in height if watered, but is usually shorter, preferring to spread out in a dense, compact, naturally rounded shape that needs little maintenance.  It does not propagate naturally in the DFW region, but does well when planted.  Most plants are found in yards, hedges around shopping centers, or boulevard medians.

Texas Sage; a compact shrub with light grey, fuzzy leaves which blooms periodically with masses of purple tube flowers.

Note; oval, slightly pointed, light grey leaves are densely arranged in an alternating whorl.

Note; all Texas Sage shrubs in an area will burst into flower at the same time, covering the plant with pungent, lavender blooms.

Note; lavender tube flowers, the throats speckled with orange or red, open up to a corolla of 5 lobes, two pointing up, three pointing down.

Sumac; Prairie and Smooth Flame-Leaf Sumac

Sumac; Prairie and Flame-Leaf/Smooth Sumac Rhus copallina L;. As the name implies, the leaves of this woody, deciduous shrub turn bright red in the fall.  The trunks have low, rough, corky knobs, but are otherwise smooth and unfurrowed.  Long (10-14”) pinnate leaves bear opposite pairs of slightly asymmetric, lance shaped leaflets. Terminal clusters of tiny greenish-white, fragrant flowers bud from the ends of this year’s growth, each with 5 petals arranged around a central disk.  Flowers convert to heavy stalks of hard, dark red berries (some varieties are white).  Though small and inconspicuous, sumac has many uses.  The resin of this Sumac has a copal like property, and can be burned as an incense, earning it the scientific species name copallina.  The stems and bark contain high levels of tannin, used for curing hides, and Amerindians crushed the berries to make lime-laced water taste palatable.  The berries are a rich source of food for birds migrating through DFW in the early spring. Two nearly identical varieties grow in the area, the Prairie Flame Leaf has toothed edges on the leaves, but lacks wings on leaf stems, while the flower petals are longer, and whiter.  The Smooth Flame-Leaf has a smooth, untoothed leaf margins, with flattened wings on leaf stems, while the flowers are more rounded, and have a darker colored disks, but both varieties are considered one species.  (632-633) 5/10/15; 5/30/16; 5/15/17 – 5/30/17; 6/2/18; 19 no obs. 5/20/20

Note; flowers convert to dense panicles of dark red (or white), hard berries, readily eaten by migrating birds in the spring

Flame Leaf Sumac habit; a densely branching, deciduous tree with relatively smooth bark, bearing alternating, compound pinnate leaves and panicles of white flowers that convert to dense clusters of dark red berries.

Note; the relatively smooth bark lacks ridges, or scales, but has corky rough protuberances

Note; Smooth Flame Leaf Sumac have compound pinnate leaves with an odd number of asymmetrical leaflets with smooth margins, and flattened ‘wings’ between leaflets

Note; Prairie Flame Leaf Sumac have compound pinnate leaves with an odd number of nearly symmetrical leaflets with coarsely toothed margins, lacking ‘wings’ between leaflets

Note; dense terminal panicles fragrant flowers, each with five white, elongated petals arranged around a dark central disk

Note; Prairie Flame Leaf Sumac flowers have longer, thinner petals with pointed tips

Note; Smooth Flame Leaf Sumac flowers have shorter, rounded petals

Note; leaves turn a bright, dark red in the fall, remaining on the plants for some time, earning this Sumac the nick-name Flame Leaf Sumac.

Redbud; Eastern Redbud

Redbud; Eastern Redbud Cercis canadensis L;. A low, stiff, upright, deciduous bush with multiple trunks, approaching the size of a small tree, which has crisp, matte, round to heart shaped leaves alternating along new stems, and dark grey, smooth to slightly corrugated (but not furrowed) bark that is very thin.  Main trunks are often short lived, (10-20) years, but new trunks rise from the root-base to replace them.  Mexican and Texas varieties are differentiated on the basis of how hairy the stems and leaves are, the Texas variety (texensis) being nearly smooth and hairless.  Redbud are best known for their abundant violet-red flowers, which sprout in umbels directly from trunks, branches and twigs early in the year (March), before other trees have begun blooming or putting out leaves.  New leaves bud out after the flowers have closed.  Three petals of each flower point up, while two wing petals encase ten filamentous stamen and the pistol.  Flowers convert to dark brown, flattened bean pods that eventually open on their own, scattering the small, flattened seeds. Cultivars range in color from white to purple, leaf colors from light green to burgundy, and some trailing or weeping varieties have been developed. Old Redbud trunks produce a medium brown wood streaked with black which makes attractive lathe-work.  Common in all zones, tending to be leggy in forest shade, and squat or stunted in full sun.  (553-555) (March 3/15, blasted by freeze) 3/22/15 – 4/17/15; 2/22/16 – 4/5/16; 2/21/17 – 3/25/17; 3/6/18; 3/8/19 – 4/14/19; 3/6/20 – 3/28/20;

Eastern Redbud habit; a variable understory bush with multiple, readily branching trunks, some approaching a small tree, which bears large, round to heart shaped leaves and bright purple-red flowers in early spring, directly from old growth and trunks.

Note; the dark grey, nearly black bark, is very thin, and smooth, often textured but not furrowed or corky.

Note; umbels of variable, purple-red legume flowers bud directly from old growth, such as trunks, branches, as well as last year’s twigs, before leaves grow in

Note; each flower is composed of three upright banner petals and two wing petals encasing the stamen filaments and pistol

Note; umbels of flowers are most common along twigs, attracting bees, although there is little detectable fragrance

Note; crisp, matte green, round to heart shaped leaves born alternately along new stems

Note; flowers convert to flattened bean pods, which turn black before they curl and pop open when dry, releasing the seeds.

Laurel; Mountain Laurel

Laurel; Mountain Laurel/Mescal-Bean Sophora Sophora secundiflora Lag; A stout, slow growing evergreen with leathery, pinnate leaves, each opposite leaflet a rough oval, native to Texas Hill Country.  Since it prefers limestone outcroppings, it does well enough here, though it has to be watered initially.  Spring growth produces a terminal spike, which blooms next year.  The large (6-10”) terminal clusters of showy, violet to pink flowers have a strong fragrance some might call pungent, each ½” flower opening in quick succession till the whole spike is full. The thick brownish seed pods contain brick-red seeds about ½” in diameter, used as beads by some Amerindians, thus it has also been called coral-bean.  The seeds contain a volatile alkaloid sophorine (mescal), which some Amerinds ground to powder and mixed in small portions with the Peyote Cactus, to make a narcotic that induced intoxication, delirium and a long sleep.  Thus, an alternative name for S secundiflora is “big-drunk bean”.  Otherwise the seeds are poison.  Black and grey tent caterpillars eat both the new leaves and flower spikes, so must be pulled off to ensure the plant blooms next year.  (568-569) 3/15/16 – 3/25/16; 3/20/17 – 4/1/17; 3/20/18 – 3/30/18; 4/16/19; 3/10/20 – 4/3/20;

Note; bright brick red berries in light grey seed pods

Note; leathery, spatula shaped, evergreen leaves, red to orange seeds and grey, bean like pods

Note; glossy green, leathery, evergreen, opposite, oval leaflets on compound leaves

Grape; Mustang Grape

Grape; Mustang/Champins Grape (rough/hairy wild) Vitis candicans?/champinii?; This wild grape has dark, rough, rounded or heart shaped leaves which have a light, hairy texture on the undersides and on new shoots.  The leaves, arranged in an alternating pattern along the stems, have scalloped rather than toothed margins, feel soft to the touch, and usually have a climbing tendril growing from the opposite side.  Fuzz on the underside may drop off as they age.  Several variable, similar looking species grow on the ILC, preferring full sun, where they drape low shrubbery. They may climb some, but tend to be brittle, and easily break under very much weight.  Tiny flowers, made up of only pistols and stamen (no petals), are born on open, drooping racemes, and though few are pollinated, they withstand the summer heat.  Fruit have several nutlets, often juicy and sweet, if tart.  Leaves not infrequently have reddish galls.  (714-731) 4/15-/15; 4/20/16, 4/22/17-5/5/17; 18 no obs; 19 no obs; 20 no obs;

Pepper, Bush Pepper

Bush Pepper; Capsicum frutescens. The genus Capsicum has been divided into four species, each with multiple varieties. The best known species is C annum, which includes Bell Peppers and Jalapenio, is the most mild, ranging from 0-10,000 in terms of hotness.  Capsicum frutescens is a small, hot pepper hardy to North Texas, and one of the few pepper plants which is indigenous to the southern USA.  A medium height (less than 2’), pithy stemmed member of the tomato family that branches regularly in a rigid angular pattern from each node, with lance shaped leaves, somewhat clammy to the touch, so broad they are almost heart shaped.  Tiny white, forward pointing flowers, blooming in late summer, are born singly on stems that point upward, looking somewhat like White Nightshade flowers, except that they do not nod, and lack the prominent, yellow, fused anthers.  The fruit are tiny (3/8”) peppers which turn yellow, then red-orange when ripe. It has been rated at 30,000-70,000 in terms of Scoville hotness, (2,500,000 is the max).  Forested areas, or forest margins on SWk.  (907-908 Vines) 8/28/18; 19 not recrd;

Bush Pepper habit; a medium height, regionally perennial pepper with broadly lanceolate leaves on long, alternating stems, bearing solitary, white flowers that convert to small, oval peppers that are mildly hot

Note; leaves are mildly clammy, the smooth stems zig-zag, and the leaves are held in an alternating pattern within a single plain

Note; the small, white flowers are born singly from leaf axils, the peduncles pointing up, the five petals only slightly nodding.

Woolywhite

Woolywhite (Old Plainsman) Hymenopappus artemisiifolius. A pithy stemmed flower over 2” tall, which begins as a rosette of coarse, narrow, compound pinnate leaves in which the pointed end leaflet is longer and more lance-like than side leaflets.  Leaves have no stem but do not clasp the stiff stalk.  As the smooth stalk grows, the leaves are arranged in an alternating spiral around it, becoming less complex toward the top.  The loose inflorescence branches frequently from leaf nodes in a spiral pattern, dividing into sprays of small flower heads.  Each head is composed of tiny, white, papery flowers with yellow centers,  so tightly clustered they look like one large, complex flower.  Pistols and stamen protrude beyond the flowers.  PL, PDU (100) 4/17/16-6/15/16; 4/7/17- ; 4/22/18; 4/28/19; 4/11/20

Thistle, Yellow Star Thistle

Yellow Star Thistle Centaurea solstitialis. More like a cactus than a thistle, this sprawling, lanky, readily branching plant has pithy, flattened, winged stems which branch in asymmetric patterns, forming a messy looking mass of spines. The long, stiff, very narrow, dusty green leaves are arranged alternately at irregularly spaced nodes, each leaf tipped with cactus like spines.  Stems potentially branch at each node, creating a tumbling habit. The flower heads are bright yellow globes that sprout from fleshy, fruit-like pedicles 3-4” long which are covered in thorns.  Common on disturbed soils, roadsides, otherwise the plant is soon crowded out by grasses and taller plants. (Pl Rn X Old Clark) (218) 6/25/15; 6/15/16- ; 6/10/17- ; 6/7/18 ; 19 not recrd;

Note; flattened, ‘winged stems’ and grey-green color

Note; tumbling, readily branching growth habit produces mounds of weakly upright stems, thorns and leaves

Note; bright yellow globe flower on a fleshy, fruit-like pedicle, with inch long cactus like thorns.

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
