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.

Rose of Sharon Hibiscus

Rose of Sharon Hibiscus; Habiscus syriacus.  Several hibiscus are cold hardy enough to tolerate Dallas’ weather.  H syriacus is originally from southern China, but was collected from Syrian gardens, hence the species name.  Although it will not propagate locally, this medium sized, pink to lavender hibiscus is locally perennial, adding a dash of color during summer months.  The tough, slightly rough, narrow, but miltilobed leaves alternate along woody stems, sprouting again from leaf nodes in late spring.  The five lavender to soft pink, or even blue petals have a darker basal spot where they connect to the long pistol, which like other hibiscus, sprouts short stamen tipped with white anthers toward the tip.  The ovaries ripen into dry capsules that crack into 5 sections, allowing the seeds to disperse.  Although it can tolerate full sun, this hibiscus does best where the afternoon sun is dappled by shade trees, but it will not do well in dense shade.  Mature “trees” have several erect, somewhat leggy, weakly branching ‘trunks’.

Note; a weakly branching, erect, woody tree like bush with narrow, deeply lobed, rough, alternating leaves, producing pink to lavender flowers with a darker basal spot.

Note; alternating leaves with somewhat narrow, deeply cut leaves.

Lantana, Calico Lantana

Lantana; Calico Lantana Lantana urticoides/horrida. A native of central and south Texas, this deciduous, invasive plant quickly spreads onto poor, overgrazed, or disturbed soil.  A first generation succession plant, it can provide ground cover to reduce erosion, and can help stabilize leaf litter and add humus to the soil.  However, its leaves have a pungent smell, it stalks are lined with tiny, stiff, and sharp spines, and its juicy blue-black berries are poisonous to most animals, making it unpalatable to most livestock, hence the alternative species name, horrida.  Locally, Lantana is a deciduous perennial, but it cannot withstand severe freezes of northern clines.  Mildly fragrant, clustered flower heads begin as yellow, but turn lavender, purple, and red over time, hence the name ‘calico’.  Sphinx moths pollinate the flowers in the warm air of summer evenings, and several green orb spiders set up their webs for smaller fair that are attracted to the flowers.  Unlike many Texas natives which flower before leafing, Lantana blooms from new shoots that leaf out first.  The large, folded leaves, born in opposite pairs, have coarsely toothed margins.  DFW is in the extended range of Lantana, so while it will survive if planted and watered, it does not propagate locally, and so is restricted to gardens and flower beds.

Note; dense heads of 5 petal tube flowers begin as yellow, turning lavender with age.

Note; stiff, woody stems lined with ridges of small, stiff, sharp thorns

Note; days old flowers turn lavender with red centers around a nectar tube.

Note; bunches of juicy, blue black berries are strong smelling, and poison to most animals, though some birds eat them

Viburnum, Rusty Blackhaw

Viburnum; Rusty Blackhaw Viburnum Viburnum rufidulum Raf;.  A small, understory, evergreen tree with cubed, but not ridged, corky bark, V rufidulum yearly produces new sprigs of glossy green, oval leaves with a very finely toothed margin, arranged in opposite pairs along the stems, completely lacking any drip-tip.  New stems, often long arching suckers off of the main trunk and branches, have a slight layer of rusty colored fuzz, giving the plant its descriptive name. Panicles of small, white, tube flowers that are mildly fragrant, bud from the ends of new growth.  The short tube ends in a corolla of 5 petals, with five white stamen, each tipped with a yellow anther, protruding beyond the profile of the flower, giving the bunches a slightly fuzzy look. The fruit are oblong, dark blue drupe with a single seed. Viburnum cultivars are popular in hedges, both for their yearly bloom of large, showy bunches of white flowers, and their glossy, evergreen foliage. (957-958) 3/30 – 4/15/15; 3/15 – 4/5/16; 3/22/17 – 4/7/17; 3/28/18; 19 no obs; 3/25/20;

Note; terminal bunches of white tube flowers that unfold into a corolla with 5 petals, the white stamen tipped with yellow anthers protrude beyond the profile of the flowers, giving the bunches a fuzzy look

Note; the dark bark is corky and divided into cubes, not furrowed ridges.

Note; bright, evergreen, glossy, oval leaves with very fine serration along the margins, are arranged in opposite pairs along stems, completely lacking any drip-tip

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.

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. (856) 5/28/15- ; 16 not recrd; 17 not recrd; 5/26/18; 19 no obs; 5/10/20;

Glossy Privet habit; an upright, evergreen bush with tree like trunks, often mottled with lichens, which bears large, opposite, glossy, oval leaves, and terminal panicles of showy, white flowers

Note; opposite, glossy, dark green, pointed, egg shaped leaves with a sharp drip-tip stay on the plant for several years

Note; terminal panicles of showy, white flowers with a mild fragrance, each flower composed of four rounded petals, stamen and pistol emerging beyond the flower profile

Note; each shallow tube flower has four rounded petals, two white, filamentous stamen tipped with cream colored anthers extending beyond the flower face

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

Note; evergreen, dark green leaves born in opposite pairs along stems.

Note; showy, terminal panicles of fragrant white flowers, each with four elliptical petals, and two white stamen tipped with purple anthers.

Note; each flower has four elongated, slightly curled, white petals arranged around a short, central tube from which two stamen, tipped with an anther, protrude

Note; flowers convert to black/dark blue, oval to round berries, eaten by many migrating birds

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. (787) 5/15/16; 5/8/17; 5/25/18; 5/25/19; 5/27/20;

Note; terminal, dense panicles of round buds open nearly all at once, weighing the stems down

Note; glossy, crisp, oval leaves are arranged alternately along new growth, which are leggy and brittle

Note; round buds open to frilly, crape like petals and curved pistols and stamen that protrude beyond the flower profile

Note; flowers have a lite, pleasant fragrance most obvious during the heat of the day

Mimosa; Mimosa Silk Tree

Mimosa; Mimosa/Silk Tree Albizia julibrissin Durazz;. A native of Asia, this deciduous, smooth barked tree of medium height thrives in hot weather and tolerates drought, winning it popular use in decorating southern coastal cities.  Otherwise, unlike the Neem tree, it does not take over wild lands.  The alternating leaves are doubly compound, being fronds up to 12” long composed of leaflets up to 4” long arranged in opposite pairs along leaf ribs, themselves composed of tiny, oblong leaflets in opposite pairs.  The fragrant flowers, born on terminal spikes, are pink-red, fading to white toward the center, so covered in silky stamen that they appear as fluffy hemispheres. The flattened seed-pods are up to a foot long, the seeds forming regular lumps under the surface. (500-501) 5/18/16; 5/20/17- ; 5/22/18; 5/25/19; 5/24/20;

Note; flowers convert to flattened bean like pods, the seeds embedded in fibrous pod sections

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;
