for the Green Industry Ahead

We

can put another spring in the books, and from all indications, it was a very good sales season. In East Tennessee, we had a dry spring, which made it a little tough on the watering, but it helped the retail markets, which in turn helped the wholesale side. We had only one rainy weekend this season, and that is very unusual; normally, we have four or five wet weekends. I do hope that we are not starting into drought season this summer, but I think the averages are back near normal since the summer storm season has begun.

I have talked with growers around our region and across the state, and everyone seems to be in consensus that sales are up and that they have started to see a shortage of material. Large-caliper trees and dogwoods are very hard to find in any area of Tennessee and also in any of the surrounding states. I would encourage everyone to refer customers to local growers and/or contractors for items or services that you do not have available.

The TNLA Buyers Guide would also be a good source for everyone to refer customers and to use as a marketing tool for your business. We are now in the process of assembling the 2016/2017 Buyers Guide, so join in on this great opportunity.

I realize we often think of other growers/contractors as our competition, but I know from experience that we can accomplish more by working together as an industry.

Remember to mark the week of October 3, 2016, on your calendar, and plan to attend some or all of the Tennessee Green Industry Expo events that have been planned for that week. Whether you like to play golf, enjoy live entertainment, tour nurseries, socialize with other growers, attend the tradeshow or shoot sporting clays, it will all be there for your pleasure. I plan to invite several guests to the golf tournament and sporting clays, and I hope everyone will. Booth space is still available for the tradeshow, so please contact our office for information.

In closing, I would like to leave you with a thought I read in the farmers’ advice column of the Appalachian Tribune. If you think you’re a person of some influence, try orderin’ somebody else’s dog around. That will keep you humble.

What Grows There?

A Handy Guide for Identifying Nuisance Fungi that Commonly Occur on Bark Media and Mulches

W

ood, bark and other forest by-products are used extensively as potting media for commercial nurseries and as mulches in landscapes. Unfortunately, these organic substrates provide the perfect growing media for several common nuisance fungi.

Although these fungi are not harmful to the plants growing in the media, they are often unsightly and aesthetically unappealing, or they are malodorous and can be disagreeable to the final consumer. These fungi can also speed decomposition of bark substrates and mulches.

Identifying these nuisance fungi can help growers and consumers ease fears and prevent unnecessary chemical applications.

Many fungi are considered a nuisance in potting media, greenhouses and landscape mulches. Let’s take a look at some of the most common nuisance fungi.

Photo 4. Yellow houseplant mushroom, Leucocoprinus birnbaumii.

Bird’s nest fungi These are aptly named for their vaseshaped resemblance to a tiny bird’s nest complete with a cache of eggs (see Photos 1 and 2). The fruiting structure varies in size depending on the species but is usually in the range of 5 to 12 mm (1/5 to 1/2 inches) across. The “eggs” are a group of spore sacs called peridioles.

Dispersal of the spores occurs when a drop of water hits the cup and the eggs are splashed out as far as seven feet.

A number of genera and species make up this group of fungi, with the most common being Cyathus and Crucibulum spp. These fungi can cover house siding

with black specks that are difficult to wash off. On greenhouse and nursery plants, the peridioles can look like insect frass and be so numerous on foliage that they cause the grower to believe it’s an insect infestation.

Peridioles of this group are easily recognized, as they often have a length of white, hyphae attached called a funicular cord.

They do not cause damage to the plants, and there is no need to control them.

Artillery fungi In the genus Sphaerobolus, artillery fungi are much smaller (0.04 to 0.1 inches or 1 to 3 mm) than the bird’s nest fungi and therefore are often not as visible and

Photo 5. Elegant stinkhorn, Mutinus elegans.

are difficult to detect (Photo 3). These “cannons” can send the single spore sac (shot from the tiny fruiting body) as far as 17 feet.

Like the bird’s nest fungi, they do no damage to plants, but the tiny projectiles can cover leaves, plant labels and siding and are unsightly and often difficult to remove.

Artillery fungus is commonly found on hardwood mulch. Choosing an alternative mulch or mixing mushroom compost with mulch can reduce the incidence of artillery fungus.

tennessee greentimes Summer 2016

Leucocoprinus birnbaumii is commonly found growing in containers in greenhouses and houseplants (Photo 4). As the common name indicates, it is easily identified as a yellow mushroom 1 to 4 inches tall. The cap usually has a nipple in the center and is 1 to 3 inches across.

There are reports of this mushroom causing gastrointestinal discomfort in some people, so it is not advisable to eat this mushroom, but it is not damaging to the

plant, and there is no control recommended.

They can be enjoyed as an unusual color surprise in houseplants. Containers infested with Leucocoprinus may have an extensive network of mycelium throughout the bark substrate, which may affect water retention.

Stinkhorn Stinkhorn is the common name given to a number of fungi that are common in landscape wood mulches, three of which are discussed here. Stinkhorns are often first noticed as a slimy, gelatinous, white egg-shaped mass buried in mulch.

The stinkhorns emerge from this structure and are identified by their shape.

The Elegant Stinkhorn (Photo 5), Mutinus elegans, forms a single pink to red narrow column that’s 4 to 7 inches tall.

Sometimes the top portion will be covered with a brown slime. The Starfish Stinkhorn (Photo 6), Aseroe rubra emerges from the egg as a hollow white stalk topped with a crown of deeply divided arms radiating from the center like a flower. The Columnar Stinkhorn (Photo 7), Linderia columnata erupts from the egg as 5 to 7 spongy red to orange columns that are joined at the top that can grow 6 inches tall.

As indicated by the name, all are identifiable by the putrid smell they produce at maturity. When conditions are ideal, they can emerge in large numbers and be very malodorous. They are often detected by their odor long before they are observed.

Flies and other insects are attracted to stinkhorns and disperse spores. They are usually short lived and do not last long, but they can be removed by hand if needed (rubber gloves are recommended).

Dog vomit slime mold This mold is not a fungus but is included in this discussion because it looks like a fungus and is a nuisance in bark mulches (Photo 8). It is in the Kingdom Protista like the amoeba. This organism, Fuligo septica appears in early evening as a white-to-yellow gelatinous mass that slowly moves across mulch. In pre-dawn hours, this slime mold contracts to form soft crusty growth, which is sometimes mistaken for something a dog threw up.

It can appear in mulch, lawns or even bare ground. It is extremely common on hardwood mulch. As with the other fungi, this growth is not harmful, does not last long, and control is not required. tennessee greentimes SUmmer 2016

Other common fungi Other common fungi found in mulch include Coprinoid mushrooms (ink caps), Leucoagaricus americanus, Gyromitra esculenta (false morels, Photo 9) and puffballs (Photo 10) such as Geastrum, Lycoperdon and Scleroderma.

None of these fungi are harmful to the plants they grow adjacent to, but they are often the subject of frantic calls or emails to plant diagnostic labs and University Horticulture Departments. Being able to identify these nuisance fungi is useful in educating consumers as well as possibly preventing unnecessary chemical applications.

In the Landscape

Echinacea ‘Cheyenne Spirit’

PROMISING AND PROVEN PERENNIALS Lavandula x intermedia ‘Phenomenal’ This vigorous grower needs well-drained soil to survive the persistent problems associated with lavenders in heavy wet soils, but this cultivar has a great mounding habit with foliage that is robust and has a silver-grey color. Foliage persists in winter, providing interest.

Echinacea ‘Cheyenne Spirit’ We are still enamored with this 2013 AAS winner because of its ability to reliably flower from seed its first season.

The seedlings produce a variety of warm colors, from soft, pastels to rich, deep shades of red, yellow and orange.

Cyclamen hederifolium, Hardy Cyclamen Small pink and white flowers appear in mid-fall, with foliage emerging a few weeks later. Hardy cyclamen is best suited for shady, woodland-type areas of dry shade. Naturalizing where planted, these gems can add a splash of flower power when the other colors in the landscape are from fall foliage. Mottled foliage remains evergreen throughout winter, disappearing in early spring.

tennessee greentimes Summer 2016

Rose: Love and Peace™

Sedum Rock ‘N Grow™ ‘Pure Joy’ This low-mounding sedum from Proven Winners reaches a height of only about one foot. It develops a huge head in summer covered with pink blooms that eventually turn to a dried seedhead that can provide fall and winter interest.

Geranium ‘Gerwat’ Rozanne The Perennial Plant of the Year in 2008, this long-blooming, hardy geranium looks great when massed together. It can take full sun when well watered; otherwise, it can use afternoon shade. It performs best with well-drained soil.

Dendranthema ‘Igloo’ Series, Hardy Mum We featured ‘Fireworks Igloo’ from Blooms of Bressingham® in the past, and as more colors are introduced, we find the results are the same. This standout mum develops a perfect mound of flowers.

These tidy, deer-resistant and butterflyattracting perennials will bloom in June and then again in September. The flowers last well into frost. Their domed habit creates a mound of 2' tall by 2.5' wide.

Mass them in mixed borders with ornamental grasses, asters and stonecrops.

Many colors are available with clever names like ‘Cool Igloo’ (raspberry),

Rose: Rainbow Sunblaze®

‘Frosty Igloo’ (white), ‘Rosy Igloo’ (coral red), ‘Sunny Igloo’ (yellow) and ‘Warm Igloo’ (orange/bronze).

Hibiscus Summerific® ‘Summer Storm’ From Proven Winners, this long-blooming hibiscus blooms summer through fall.

Huge 8" to 10" light-pink flowers bloom against burgundy foliage. Height reaches 48" to 60" with a 40" to 48" spread. For bushier plants with more blooms, one or two pinches will do the trick.

Agastache Kudos™ Gold, Dwarf Hummingbird Mint

From Terra Nova®, this dwarf variety is very hardy and resistant to downy mildew.

Great pollinator attractant, with long, slender spikes. About 18" tall and 20" wide. Starts blooming in late May and keeps blooming until frost. Can be sheared back in mid-summer to reinvigorate.

Amsonia hubrichtii, Arkansas Blue Star One of our old favorites. Feathery foliage up to 3' tall gives this plant a very airy feel as it blows in the wind. Add striking blue flowers in spring and brilliant golden to copper fall color, and you have a winwin for this underutilized plant.

Rose: Spellbound™

Rose: Sugar Moon™

Rose: Twilight Zone

REMARKABLE ROSES Love and Peace™ A perennial staff and visitor favorite, this hybrid tea has a bushy habit resulting in lots of blooms of soft yellow and rich pink. It’s consistent in bloom size and color.

Rainbow Sunblaze® As colorful as its name implies, this mini rose blooms deep, rich yellow with rich pink margins fading to a reddish-pink as each bloom ages. Very floriferous, blooming all season long.

Twilight Zone This double-flowered grandiflora rose has an old-fashioned appeal. Its deep velvety magenta-purple petals and strong scent make it appealing as specimen, mixed with other roses or in a group.

Spellbound™ A disease-resistant hybrid tea with large blooms and clear coral blooms.

Sugar Moon™ A large-flowered hybrid tea with purewhite blooms and a wonderful fragrance.

TREMENDOUS TREES & SHRUBS Cercis canadensis ‘Whitewater’, Whitewater Eastern Redbud This tree has it all! Weeping form, variegated foliage and rose-purple blooms. Leaf variegation is very pronounced. It’s a cross between ‘Silver Cloud’ and ‘Covey’ out of NC State. Filtered afternoon shade should help keep variegation from burning.

Stake as high as you want it to grow.

Lime®

Little Hydrangea paniculata ‘Jane’, Little Lime® Hydrangea Jane We find we are utilizing this dwarf hydrangea more and more because its scale fits well into so many landscapes.

It grows from 3' up to 5' tall, with softgreen blooms turning to pink in fall.

Tolerates part sun to full sun.

Little Lime® Hydrangea paniculata ‘Jane’, Little Lime® Hydrangea Jane

Juniperus virginiana ‘Taylor’, Taylor Juniper An ideal plant for that Tuscan feel. This columnar juniper maintains its dense upright form with no tendency of lodging.

Blue-green foliage can add a dramatic effect in the landscape. Reported to stay 3' wide up to 30' tall.

Acer palmatum ‘Mikawa Yatsubusa’, Mikawa Yatsubusa Japanese Maple Dwarf specimen tree with tightly layered green leaves that turn yellow to orange in fall. Reaches 3' to 4' in ten years.

BloomStruck® Hydrangea macrophylla ‘P11HM-11’, ® Bigleaf BloomStruck Hydrangea 18 tennessee greentimes Summer 2016

First Editions® Loropetalum chinense var. rubrum ‘PIILC-1’ Crimson Fire™, Crimson Fire Chinese Fringeflower

Acer palmatum ‘Tsukasa Silhouette’, Tsukasa Silhouette Japanese Maple A columnar form developed in Japan by Yutaka Tunakam, this Japanese maple was named in the U.S. by Don Shadow, reflecting the nursery from which it came and its growth habit. Rich, deep green in summer that turns orange to bright red in fall. Can reach 15' to 20' tall by 6' to 7' wide.

BloomStruck® Hydrangea macrophylla ‘P11HM-11’, BloomStruck® Bigleaf Hydrangea

Another in the line of Endless Summer® re-blooming mophead hydrangeas, this one displays vivid purple or rose-pink flower heads on sturdy, red stems. Its flowers are smaller than other cultivars, but there are more of them. Does best in partial shade with well-drained moist soil. Height 3' to 4' by 4' to 5' wide.

Change the color by adjusting pH (acid for blueish or alkaline/sulphur for pink).

Heat tolerant and disease resistant.

First Editions® Loropetalum chinense var. rubrum ‘PIILC-1’ Crimson Fire™, Crimson Fire Chinese Fringeflower Low-growing fringe flower with a compact and spreading habit. 24" to 30" tall. Rich, ruby-red foliage with neon-pink flowers. Improved cold hardiness is one improvement that we are still testing. Spring planting is best.

Zone 7 to 9.

In the Landscape

Lagerstroemia ‘PIILAGIII’ Red Rooster®, Red Rooster Crapemrytle Great new crapemyrtle with true-red flowers with an upright, mid-size growth habit. Resistant to powdery mildew.

Illicium parviflorum ‘Florida Sunshine’, Florida Sunshine Anise Shrub Chartreuse-gold foliage during the spring and summer brightens to screaming yellow in the fall. In winter, the yellow becomes a bit more muted, with the upper stems taking on a red cast, contrasting with the leaves. Best grown in average to moist soil in light shade to prevent leaf scorch. Its mature size is unknown, but expect it to reach 5' tall x 3' wide in 7 years.

Spiraea thunbergii ‘Ogon’, Ogon Spirea This shrub offers very early spring bloom, gorgeous golden foliage throughout the summer and lingering fall color. Ogon spirea moves softly in the breeze, adding a diaphanous quality in direct contradiction to its sturdy constitution. It makes a brilliant contrast against plants with leaves or, even better, with plants of purple or bronze foliage.

Ginkgo biloba cultivars Several cultivars are available that have desirable characteristics. ‘Autumn Gold’ is said to exhibit the most striking fall color, but Presidential Gold™ and ‘Golden Globe’ are also favorites. ‘Chase Manhattan’ is a dwarf, small-leafed cultivar that can reach 6' by 6' in 10

years. The UT Gardens, Knoxville, has a dwarf, high-graft, multi-branched cultivar named ‘Merikan’ that is about 6' tall and looks like a golden lollipop in fall. Both of these cultivars are ideal for the smaller landscape.

Salix x ‘Flame’, Flame Willow This wonderful, graceful shrub willow displays brilliant orange-red stems in winter, similar to shrub dogwoods. Can get 20' by 15' at maturity but can be kept in check for smaller areas by rejuvenation pruning (which also promotes new growth that will have better color). In summer, the lanceolate leaves create a graceful shrub. Fall color is golden yellow. This very forgiving plant that can be grown in a variety of conditions, from dry to moist, but it does best in full sun. C
