Chickasaw Plum Prunus angustifolia

Chickasaw Plum Prunus angustifolia. A thicket forming, twiggy bush which has sharp thorns along the branches, this fruit tree is common on open land along water courses and road sides.  Blooming later than P umbellate, which produces umbels of flowers on the ends of stems, Chickasaw Plum produces white flowers along the full length of stems, making a display of total white “bottle brushes”.  The ½” fruit begins green, turns red, then yellow when it is ripe.  The leaves are soft and serrated along the edges, but longer and thinner than P umbellate.  Like other members of the cherry and plum family, the leaves are toxic to livestock and rabbits.  Each individual, sweetly fragrant flower is composed of 5 oval petals surrounding a central pistol with many filamentous stamen.  Known clumps are most prevalent under the power lines along the DORBA trails.

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

Soapberry, Western Soapberry

Soapberry; Western Soapberry Sapindus drummondii Hook;. Soapberry can grow to be a branching crown tree in some areas, but in the DFW area it is normally a short, spindly, deciduous bush of the understory, rarely more than 4” in diameter.  The loose, light grey, extremely scaly bark is often tinged with yellow or orange lichens.  Light green shoots produce a new crop of oddly pinnate leaves which alternate in a spiral around the stems, the asymmetrical leaflets alternating along the ribs, rather than being arranged in opposite pairs.  Leaves turn bright yellow in the fall.  Flower panicles, 6-10” long, bud from the tips of new growths, bearing tiny (1/4”), fragrant, short-lived, white flowers with 5 papery thin petals.  Flowers have 8 or more stamen, each tipped with an off-white anther, which project out, far beyond the flower, giving the flower heads a fuzzy look.  Flowers convert to yellowish, translucent berries with a solid pit, which look similar to Chinaberry seeds.  When dried, the saponin rich berries can be vigorously rubbed in water to produce soap-suds.  Otherwise, the berries, though used in moderation as a purgative and antiseptic, are considered toxic.  Trees are parasitized by the Soapberry Borer beetle, which eats away the water carrying xylem layer under the bark.  (683-684) 5/28/15 – 6/5/17; 5/25/17 – 6/5/17; 5/25/18; 19 no record; 5/28/20

Privet; Glossy Privet

Privet; Glossy/Japanese Privet Ligustrum lucidum var. macrophyllum Ait;. Much bigger, more upright, and less aggressive than L sinense (Chinese privet), this vigorous, invasive, hardy, evergreen, ornamental from south-eastern Asia is more of an understory tree than bush.  The smooth, light grey bark of the trunks, often mottled with lichens, bear large (2-4”), glossy green, pointed leaves that are arranged in opposite pairs along long (6’+) arching stems.  More upright, L lucidum is an understory tree with 3-6 trunks, and though the stems might take root if they touched the ground, they rarely do. Terminal panicles of fragrant, white flowers, each with 4 rounded petals, grow out from the axils of new leaves and the ends of last year’s stems.  Flowers convert to blue-black, oblong fruit which remain on the bush through the winter, providing spring food for migrating birds.  L lucidum is common both in the thin soils of limy high ground and the deep soils of lowland flood plains.

Privet; Chinese Privet

Privet; Chinese Privet Ligustrum sinense Lour;. This leggy, drooping, invasive, evergreen ornamental shrub was imported for its terminal spikes of fragrant white flowers and green foliage.  Privet sports multiple, small, trunk like stems which sprout from a central, shallow, bulbous root, sprouting new growth from the base and from branches in March, then developing terminal sprays of flowers which open in April or May.  Flowers convert to small, oblong, blue-black fruit that soon ripens, but does not fall until the next spring (March).  The mass of showy, fragrant flowers are white, with 4 elongated petals, arranged around a short tube, from which two filamentous stamen protrude, each tipped with a purple anther.  Pointed, elliptical leaves are born in opposite pairs along new stems, remaining for several years.  The long thin, brittle new shoots are easily snapped, but grow back quickly, gradually bending over if not supported, till they touch the ground. They will take root if they touch, so privet needs to be cut back twice a year to keep it in check.  Older trunks develop a knobby surface with sharp, spike like protuberances where opposite leaf ribs once grew. This privet has taken over large areas of moist bottom land, forming interlaced understory thickets that are nearly impenetrable without a machete or hardy nippers.  The roots are shallow and the stumps easily removed, but Privet can grow back from roots.  Privet does not colonize open grass land, as it does not tolerate full sun. (857) 4/25/15; 5/25/16; 4/18/17- ; 4/18/17; 5/20/18- ; 5/4/19; 5/15/20

Crape-Myrtle; Ladies Streamers

Crape-Myrtle; Crape-Myrtle/Ladies Streamers Lagerstoemia indica L;.  This relatively small, deciduous, multi-trunked tree, originally from drier parts of India, grows from a bulbous base, allowing it to survive fire, drought and flooding.  The smooth, reddish-brown bark sheds in layers, revealing greyish new bark underneath.  Though hardy, and having viable seeds, this commonly planted cultivar, grown for its attractive flowers and foliage,  has not been known to reproduce itself in forests, or on the prairies.  In yards, the tree sprouts, often as not, from roots, rather than its seeds.  An evergreen in tropical environments, but deciduous in temperate zones, or regions with a prolonged dry season, it tolerates Dallas summers, blooming in July.  New growth and suckers sprout in May, the attractive, glossy, oval leaves arranged in an alternating pattern, followed by terminal panicles of round, purplish buds which open to 1” showy, lightly fragrant flowers with crape like petals born on filaments, and curved pistols and stamen that project well beyond the petals.  Modern hybrids range from white to deep red to purple.  Flowers convert to black capsules less than ½” across, filled with small, hard seeds.  New shoots, covered in a light grey powdery substance, can grow as much as 5’ in one season, needing yearly pruning to shape the tree and encourage blooming.

Magnolia; Southern Magnolia

Magnolia; Southern Magnolia Magnolia grandiflora L;.  Dallis is considerably west of the natural range of Magnolia, and too dry for it to go native, but it is commonly planted as an ornamental tree, where it thrives if watered.  The large, thick, stiff, evergreen leaves are dark, glossy green above, rust-brown to purple on the underside, beginning as ‘pig-tails’ that unfurls as they open. If grown in full sun it attains a conical shape, the lower branches spreading out radially from the smooth, dark grey trunk, and drooping slightly.  Large, white, cone shaped buds open up into huge (5-8”), fragrant (lemony smell), brilliant white flowers, the cupped petals arranged radially around a central, fleshy cone, from which white anthers protrude.  The petals fade to cream, then brown two days before falling off.  The fleshy cone turns reddish, then brown as bright orange-red seeds mature and poke out of the cone bracts.  Beetles pollinate this flower. The flowering season can last into Fall if the summer is cool and the Fall mild. (280-281) 4/29/15; 4/26/16-; 5/2/18; 5/6/19; 5/1/20;
