Arboretum at Utah Botanical Center Named In Honor of Past Director
by David Anderson, Utah Botanical Center

We celebrated Arbor Day last week in fine fashion! It was wonderful to recognize the value of trees in our lives - and to honor our friend and colleague Bill Varga in the process. The Varga Arboretum was opened at the UBC with a great group in attendance. We are so pleased to have this new area underway at the UBC.

Many other things will be happening this spring and summer at the UBC including the installation of boardwalks and additional solar panels at Wetland Discovery Point classroom, a packed to the gills fish camp, environmental education field trips, Aggie Adventure camps, spring plant sale, farmer's market and our food bank garden - just to name some.

Exciting activities are also happening at the Ogden Botanical Gardens, including a special 15th anniversary celebration in June. We invite you to visit our Web site regularly to stay up-to-date on activities and events. OBG and the UBC are working hard to serve as community-building places - connecting people with one another and with the environment.

Featured Pest:
Lawn Insects
by Jerry Goodspeed


The lawn is one of the whiniest plants in the landscape.  It seems as if any insect that wanders near the lawn causes it to weaken, go brown, start to holler and then die. This can be really upsetting aft
er all the work of mowing, fertilizing, aerating, sweating and fretting just to keep it green. There are a number of insects that can damage the lawn, including the white grub, bluegrass billbug and the sod webworm. Each has a little different life cycle and does a little different damage, but they all can be quite destructive if left unchecked.
The best defense is to keep the lawn as healthy as possible. Make sure to water properly (don't over water), cut the grass about 2 inches tall, aerate once a year, and fertilize. However, even a healthy lawn may not be enough to keep the critters out. If you suspect you have an insect causing damage on the lawn, here are some helps for control:
      1.  Properly identify the insect causing damage. Dig around the edges of the damaged area to find the pest.  White grubs are large, have three sets of prologs near their head, and form a "C" shape when disturbed. Billbugs are smaller white larva with a light brown head and no prologs. Sod webworms are typically brown with black spots on their bodies.
      2. Determine a control method. There are both preventative and curative options available.  Most preventatives are put down in May before the damage is done, while the curatives are used later in the summer once the damage is noticed. Contact your local nursery for available products.
      3. Monitor the area to insure you are obtaining the desired results. You may also need to reseed an area if you have had some severe damage. 
      4. Be patient and a little tolerant. After all, we are dealing with Mother Nature. For more information go to http://utahpests.usu.edu/insects/htm/factsheets/by=category/category=149.



Featured Tree:
Common Hackberry
by Jerry Goodspeed

Common Hackberry
(Celtis occidentalis)
Size: Large (over 50 feet at maturity), good for parks, yards and fields
Ornamental Characteristics: Average to good yellow/gold fall color, no flowers or noticeable fruit, but does have attractive bark
Shape: Somewhat vase
Pests: None of significance
Other: The small, dry fruit can bring some birds into the landscape. Since the fruit dries up on the tree, they do not present a cleanup problem.
Description: One of the best and most hardy shade trees grown in Utah is the common hackberry. This tree can adapt to most soil types, has few pests, and is noted as a somewhat fast grower. It is native to the eastern plains of the United States, but can be grown in much of the country. It makes a large shade tree that can be enjoyed for generations to come.



Featured Perennial:
Avalanche Feather Reed Grass
by Richard Anderson

Avalanche Feather Reed Grass
(Calamagrostis x acutiflora 'Avalanche')

Type: perennial, clump  
Zone: 4 (-30F)
Size: 2 to 3 feet tall (seedheads to 5 feet) and 1 to 2 feet wide
Description: Calamagrostis x acutilflora 'Avalanche' is a long-blooming, low-maintenance, long-lived, perennial clump grass suitable for full sun to partial shade exposures. 'Avalanche' grows best in well-drained fertile soils with sufficient moisture, but will tolerate heavier clay soils and drier sites. Fertilizer may be required to produce maximum height. Low fertility will result in shorter plants. Feather reed grasses are generally free of serious disease or insect problems, although a foliar rust disease can occur during wet summers where poor air circulation conditions exist. Little maintenance is required except cutting back the stems to approximately 8 inches in late winter or early spring. In areas with mild winters the foliage may remain evergreen. This ornamental grass is a cool-season grass, which allows planting or transplanting in spring or fall. Sterility eliminates any chance of this cultivar becoming invasive or producing unwanted seedlings in the garden. Consider combinations with late summer and fall-blooming perennials such as Perovskia, Agastache, Helianthus, and Rudbeckia. Photo Credit: Richard M. Anderson 


Down and Dirty Question:
Where did the Tomato Originate?

by Richard Anderson

According to many scholars around the globe, the ancestral form of the modern cultivated tomato appears to have originated in South American countries of Peru, Ecuador and Chile. It is believed that the tomato migrated northward into Mexico during pre-Columbian times where extensive domestication began and from where the various cultivars we have today were disseminated. Today, tomatoes are the most popular plant in the home garden. The tomato varieties 'Floramerica,' 'Fantastic,' 'Celebrity,' 'Mountain Delight,' and 'Better Boy' have all performed well in Utah and are only a few of the numerous varieties worth planting in your garden.
