Pyracantha (Firethorn) MISSION: BEAUTIFICATION … CONSERVATION … EDUCATION Planting and Nurturing October, 2020 Volume: V Number: 6 Landscape Design: Suzanne Finger, Editor Environmental Edition: May, August, November, February – Mary Lovings, Editor Gardening: June, September, December, March - Linda Doiron, Editor Landscape Design: July, October, December, April – Suzanne Finger, Editor As we swap Jack-o-lanterns for cornucopias and enter into a season of Thanksgiving, I am reminded that along with the tricks from the year 2020, we can also find some treats for which to be thankful. This brings to mind some plants that, although they may have a few tricks up their sleeves, they are a treat in our gardens. In this edition of Planting and Nurturing, I would like to explore a few of these plants we love to put up with. Pyracantha (Firethorn) Pyracantha (Pyracantha coccinea) or Scarlet Firethorn has withstood the test of time as a southern garden classic. Its showy red berries in the winter and ability to draw birds like Snickers attract kids on Halloween are just a couple of its endearing traits. Pyracantha is a versatile plant that, when espaliered, can bring life to any wall. When simply left alone, it will grow into a large, open weeping form. My mother espaliered pyracantha on the brick walls to either side of our family home's front porch. Through some misfortune, when the yard work was divvied up, I received the job of trimming the pyracantha. Through that memorable experience, I learned the value of thick leather gloves and potent wasp spray. Above and Next Page: Pyracantha coccinea This bush, commanding a prominent spot in a neighbor’s yard, was allowed to grow as a large specimen shrub. It really puts on a show each fall. Cons: Most varieties are VERY thorny! 'Thornless' is a thornless variety that is available. It features colorful berries, but has more of an open growth habit than the older varieties. Disease/Pest prone (aphids, lacebugs scale, fireblight, twig blight, and fruit scab) Can be damaged by severe cold Wasps love to make their nests in its branches (this is only from personal experience, not scientific research) Does not like to be transplanted Pros: Beautiful Red to Orange berries contrasted by rich, emerald green foliage Can be espaliered or trained to a wall Drought tolerant once established Tolerates clay soils Fabulous bird attractor Makes an attractive, yet impenetrable barrier Bamboo The mention of bamboo brings shivers to the spine of many who have battled its presence where it wasn't wanted. I would invite you to consider; however, bamboo's talents and the landscape possibilities presented by non-invasive types. There are countless types of bamboo, and for the purposes of this discussion, I will mention only two. There are the running types of bamboo, like Phyllostachys aurea, which are invasive and considered a nuisance because of how quickly they can take over an area. They pose dangers to the native landscape and wildlife as they bully their way into the landscape, stealing space and resources. These types are not recommended; therefore, we will concentrate on the clumping types, specifically, Bambusa multiplex. This species of bamboo is a clumping bamboo that sends out new sprouts from the center of the plant, slowly increasing in diameter. It has many different cultivars, one of which, 'Golden Goddess,' is a particular favorite of mine. Below: Bambusa multiplex ‘Golden Goddess’ This hedge of bamboo was planted about six years ago to create a green wall to enclose a Chinese Garden and screen it from an adjacent parking area. It is roughly 10-12 feet tall and only about 2-3 feet wide at its base. Although this lovely bamboo is considered a slow grower and non- invasive, I still like to use this plant where it will have limitations. I located this particular planting along the side of a concrete sidewalk, limiting its growth on that side. The perfect way to plant bamboo is between two concrete curbs. Its tough new shoots can push their way up through compacted ground and even asphalt, but concrete creates a significant barrier to its growth. Right: Bambusa multiplex ‘Golden Goddess’ Hemmed in by a concrete sidewalk. The canes of 'Golden Goddess' are a light golden green with leaves that float in the slightest breeze. The plant can also be trimmed to maintain a height of under eight feet. In the pictured application, it provides a small garden area with the perfect visual screen from an adjacent parking lot. Gardens with limited space can benefit from these lovely living walls. Bambusa multiplex 'Golden Goddess' is well suited to our heat and is hardy in zones 8-10. Pros: Must plant a clumping variety; otherwise, employ a goat full-time for maintenance Cons: Can create a narrow living wall to use as a visual screen Can be an effective dust barrier Is useful as a physical barrier Pet-friendly Tolerates poor soils Drought tolerant once established River Birch Batula nigra ‘Dura Heat’ This allee of River Birch creates a cool path around a water feature. "Messy!... Greedy Roots!…" These are some of the heartfelt comments often shared about the River Birch. Because of this, our native River Birch (Betula nigra) may be overlooked at times for landscape plans, but when put in the right spot, it can shine. Its exfoliating bark revealing ivory, gold, grey, and cinnamon brown colors, creates interest even when the fall breezes whisk away its light green leaves. A fast grower, the River Birch, is often used as a shade tree. River Birch, marching down either side of an allee, makes a memorable pedestrian path covered in dappled shade. This workhorse tolerates poor soils and can even handle wet feet periodically. In my planting designs, I rarely use a river birch tree alone. When grouped together, they create dynamic visual interest in the landscape. Multi-trunked specimens show off the beautiful, paper-like bark best and facilitate full, open canopies. 'Dura Heat' is a popular cultivar famous for its heat and drought-tolerant traits. Be sure to give your River Birch plenty of space to grow and keep it away from foundations and septic systems. Its vigorous root system can get it into trouble in these places. Although the River Birch loves to drop little sticks and twigs, I believe its beauty is worth the trouble in the right spot. Cons: Messy, dropping little twigs, bark flakes, leaves, and catkins. (My experience is that a hardy riding mower with a catcher does just fine on clean-up duty) Invasive roots Can get really big Pros: Fast Growing shade tree Can get really big Lovely bark providing Fall/Winter interest Tolerates poor soils Drought tolerant once established Yucca I try to keep an open mind when it comes to plants. Nonetheless, some are really hard for me to wrap my arms around (this one, literally). A love for the Yucca is a cultivated thing, and my palate is just not that refined. Both Yucca filamentosa and Yucca aloifolia are native to Georgia, primarily the coastal regions. Yucca filamentosa or Adam's Needle has the added benefit of a curly, threadlike fiber along the leaf's edges. This is an exciting Above: Yucca filamentosa feature when you observe the plant up close. For this reason, and the fact that filamentosa maintains a lower, rounded form, it is easier to imagine a place for it in the designed landscape. Historically, it was used as an accent plant on either side of rose garden entrances. I suppose an evergreen plant with a strong linear spray of leaves gave a nice contrast to the looser habit of the roses. I have also seen the filamentosa used successfully as an attractive container plant. Perhaps if I go exploring more of its attributes, I will learn to appreciate it more. Yucca aloifolia or Spanish Below: Yucca aloifolia (The “Gang”) Bayonet will have to work a little harder to win me over. I would love to hear my garden club friends debate its usefulness in the landscape design world. Maybe it would look at home in Miami? A singular plant left alone to its evil wiles can spawn an entire gang to keep it company. We usually see it at the height of about eight feet. Apparently, in its optimal environment, it can reach heights of twenty-four feet! This sent shivers up my spine. I would liken the sight of one of these to spotting a six-foot roach. I must confess that even despite my best efforts to find the redeeming qualities of this plant, my memory of accidentally backing into one when I was a teenager clouds my ability to remain unbiased. Therefore, if this plant ever ends up in court where I am selected for the jury, I will have to recuse myself. I once heard the plant described as "modern." Hmmm. Perhaps it looks good in front of a mid-century style brick ranch with an orange door? Cons: Mean Nasty Ugly Pros: Edible fruit – raw or cooked. Was a staple for some Native American Tribes Native Modern? (I'm trying) As long as there are opinions, there will be differing opinions. It is always fun to talk plants among friends, and I hope that if not informative, at least this article was entertaining. I am happy to start this Thanksgiving season grateful for the rich abundance of plant material we Georgians enjoy and a climate where we can explore our gardens year-round! What are you thankful for?

Manhattan, KS 66506 (785) 532-6173 Video of the Week: Growing Asparagus VEGETABLES Bolting and Buttoning in Cole Crop Plants Broccoli, cabbage and cauliflower are cole crops that have a tendency to bolt (go to seed) or button (produce an extremely small head) if plants are not grown properly. These crops need to be kept actively growing through their production cycle, including growing transplants from seed. If they slow down due to under-fertilization or are stunted due to overgrowing their container, buttoning or bolting is more likely. If you are not growing your own transplants but rather selecting plants from a retailer, choose small, stocky dark green plants. Even after transplanting, these plants need to be well-fertilized. Fertilize at transplanting with a starter solution and continue to fertilize every 2 to 3 weeks until harvest. Both buttoning and bolting are irreversible. Once a seed stalk starts for form, nothing can be done to force the plant to produce a normal crop. (Ward Upham) FRUIT Strawberry Mulch Removal Research done in Illinois has shown that the straw mulch should be removed from strawberry plants when the soil temperature is about 40 degrees F. Fruit production drops if the mulch remains as the soil temperature increases. There are likely to be freezing temperatures that will injure or kill blossoms, so keep the mulch between rows to conveniently recover the berries when freezing temperatures are predicted. (Ward Upham) FLOWERS Fertilizing Perennial Flowers Most flowering perennials are not heavy feeders, and once established, may not need fertilizing every year.

It has small (¾-2” long, ½” wide), dark green oblong-shaped leaves with rounded tips. The leaf undersides may be a green-gray color because of dense short hairs. Its stems are woody and sparsely covered with long hard thorns. Small white flowers (up to ¾” wide) have from 4 to 10 petals and are arranged in clumps along the stems. The fruits are red to orange in color and are less than ½” wide. Distribution: P. angustifolia has been found from Mountain View through the Volcano Golf Course in mesic forest, along disturbed roadsides and abandoned agricultural lands. It is also established on Kaua‘i. It is probably spread by birds and rats. Other Information: The firethorn bush is used as an ornamental in many places in the world, including Hawai‘i. In Hawai‘i, firethorn escapes cultivation and forms dense thickets. The thickets easily overgrow native plants, and prevent new plants from sprouting.

    RESEARCH LABORATORY TECHNICAL REPORT Apple Scab Bruce R. Fraedrich, PhD, Plant Pathology Scab is a leafspot disease that causes premature defoliation of crabapple and apple. Other species in the rose family including pyracantha and hawthorn may also be affected by scab fungi. Symptoms can also develop and drop prematurely (Figure 2). Scab lesions on fruit which can deform it and cause Apple scab is caused by the fungus Venturia inaequalis fruit drop prior to ripening. which infects leaves, petioles and fruit of its host. Initial symptoms appear as olive-green, sooty spots on Disease Cycle leaf blades and petioles on young, developing foliage. Venturia inaequalis overwinters in infected, fallen As leaves age, the infected areas form definite spots leaves. Fruiting structures, known as perithecia, form which are slightly raised, black, and velvety in on the dead, fallen leaves in late winter. Spores are appearance (Figure 1).

Spores are carried by wind currents to developing leaves and fruit where Figure 1: Apple scab leaf lesions infection occurs. Since all perithecia do not mature at the same time, spores are produced over a period of several months and as late as June. Secondary spores are also produced on leaf lesions which can cause infections later in the growing season. Control Some varieties of crabapple and apple have demonstrated resistance to apple scab.

A plant is considered exotic, (alien, foreign, non- indigenous, non-native), when it has been introduced by humans to a location outside its native or natural range. Most invasive, exotic plants have escaped cultivation or have spread from its origin and have become a problem or a potential problem in natural biological communities. For example, black locust, a tree that is native to the southern Appalachian region and portions of Indiana, Illinois, and Missouri, was planted throughout the U.S. for living fences, erosion control, and other uses for many years. Black locust is considered exotic outside its natural native range because it got to these places Kudzu is an invasive exotic plant that has spread by human introduction rather than by natural from Japan and China to become a large problem in dispersion. It has become invasive, displacing native much of the US. Local, state, and the federal species and adversely impacting ecosystems and governments spend millions of dollars per year to several endangered native bird species that depend on control the spread of kudzu. Even yearly control other plants for food, as well as several endangered may not be enough to successfully remove kudzu. Seeds can remain dormant in the plant species.

  • An Overview of the Genus Cotoneaster (Rosaceae): Phytochemistry, Biological Activity, and Toxicology
    antioxidants Review An Overview of the Genus Cotoneaster (Rosaceae): Phytochemistry, Biological Activity, and Toxicology Agnieszka Kicel Department of Pharmacognosy, Faculty of Pharmacy, Medical University of Lodz, 1 Muszynskiego, 90-151 Lodz, Poland; [email protected] Received: 18 September 2020; Accepted: 13 October 2020; Published: 16 October 2020 Abstract: Traditional herbal medicines have become a subject of global importance with both medical and economic implications. The regular consumption of herbal drugs has led to serious concerns regarding their quality, effectiveness, and safety. Thus, relevant scientific evidence has become an important criterion for the acceptance of traditional health claims. The genus Cotoneaster Medikus provides numerous species traditionally used in Asian medicine for the treatment of haemorrhoids, diabetes, and cardiovascular diseases. This review summarises the achievements of modern research on the Cotoneaster taxa, including ethnobotany, phytochemistry, pharmacology, and toxicology. To date, more than 90 compounds have been isolated or analytically identified in Cotoneaster leaves, fruits, flowers or twigs. These phytochemicals are categorised into flavonoids, procyanidins, phenolic acids, cotonefurans, cyanogenic glycosides, triterpenes, sterols, fatty acids, volatile compounds, and carbohydrates, and many of them are responsible for Cotoneaster pharmacological properties including antioxidant, anti-inflammatory, antimicrobial, antiparasitic, hepatoprotective, anti-diabetic or anti-dyslipidaemic

  • Fire Blight of Apples
    report on RPD No. 801 PLANT December 2015 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN FIRE BLIGHT Fire blight, caused by the bacterium Erwinia amylovora, is a common and very serious bacterial disease. The disease is also referred to as blossom blight, spur blight, fruit blight, twig blight, or rootstock blight – depending on the plant part that is attacked. Erwinia amylovora infects approximately 75 different species of plants, all in the family Rosaceae. The hosts for this bacterium include apple, blackberry, cotoneaster, crabapple, firethorn (Pyracantha), hawthorn, Japanese or flowering quince, mountain-ash, pear, quince, raspberry, serviceberry, and spiraea. The cultivated apple, pear, Figure 1. Infected blossoms wilt; turn light to dark brown and quince are the most seriously affected species, but on apple; black on pear. many ornamentals serve as overwintering hosts for the bacterium and are important sources of new infections each year. Losses from fire blight in apples and pears include: (1) death or severe damage to trees in the nursery; (2) death of young trees in the orchard; (3) delay of bearing in young trees due to frequent blighting of shoots and limbs; (4) loss of limbs or entire trees in older plantings as the result of girdling by fire blight cankers; and (5) partial loss of the crop by the blighting of the blossoms and young fruit. The seriousness of fire blight is demonstrated by its effect on the commercial pear industry. At one time, the pear was a popular and widely grown fruit in the Midwest, comparable in importance to the apple.

Polizu Str.011061, Bucharest, Romania Abstract. Scarlet/red firethorn, Pyracantha coccinea M. Roem., is a common ornamental shrub, commonly cultivated nowadays in Romania and many other countries, in gardens or hedges. The tree has small white flowers and it produces small bright colored berries. The fruit is bitter and astringent, making it inedible when raw. The fruit can be cooked to make jellies, jams, sauces and marmalade. In this study, the Pyracantha coccinea M. Roem fruits from three common cultivars named „Orange Glow”, „Red Column” and „Soleil d’Or”, were collected from different individuals in Constanta city, Romania. Both frozen and dried (80°C) fruits were analyzed for the active principles content such as, carotenoids, flavonoids and total phenolic compounds correlated with antioxidant activity. Carotenoids were determined by acetone extraction and UV-Vis spectrophotometry, flavonoids, by methanol extraction and UV-Vis spectrophotometry and total phenolic, by methanol extraction, Folin- Ciocalteu reaction and UV-Vis spectrophotometry. The total antioxidant capacity was quantified through photochemiluminescence method by comparison with the standard substance used for calibration, Trolox® as tocopherol analogue (ACL procedure) using Photochem apparatus, Analytik Jena AG, Germany.
