Purdue Landscape Report: These three maples have somewhat similar-looking leaves. On the surface, you may think this is simply an academic exercise. But if you care about invasive plants and local ecology, this distinction is an important one.

Norway maple is an invasive tree species, while sugar and black maples are native tree species (sometimes called hard maples). Sugar and black maples are even more beloved for their gift of delicious sugary sap that can be made into maple syrup and similar products. They also make great shade trees. Note that there are other native and non-native maple species.

One way to distinguish between Norway (Acer platanoides), sugar (Acer saccharum), and black (Acer nigrum) maples is to count the number of lobes on the leaves. Lobes are large areas of the leaf that stick out, like an ear lobe, although that is not the clearest analogy. Norway maples typically have 5-7 lobes (commonly 7), sugar maples typically have 5, and black maples typically have 3-5. Black maple’s bottom two lobes are so much less prominent than sugar maple that it often looks like 3 main lobes. Additionally, black maple leaves droop on the sides, almost like they are starting to wilt from lack of water.

Another way to distinguish Norway maples from native maples (sugar and black) is to look at the winged seeds, called samaras. Children may call these “helicopters,” as they twirl on their way to the ground. The Norway maple has paired samaras arranged like a handlebar mustache. Sugar and black maple samara pairs look more like a Fu Manchu mustache, pointing downward rather than the near horizontal arrangement of Norway maple samaras.

A third way to distinguish Norway maples from native maples is to snap off the long leaf stem (petiole). Norway maples have a milky latex sap that exudes if you squeeze or pinch a petiole, while native maples have clear sap.

There are a few other identification nuances between these species. For example, black maples have stipules (leaf-like growths) at the base of their petioles (absent on sugar maple). They also have pubescence or hairiness on the underside of the leaves. Norway maple has hairs in the axils of leaf veins. Norway maple’s leaves are generally broader than long. Other differences may be seen in the bark, twigs, buds, and fall coloring.

Although Norway maple is an invasive species, it has been a long-time landscaping favorite of homeowners, especially cultivars like ‘Crimson King’ that retain their deep red color all year. This attribute has made Norway maple a popular choice because few other options exist to offer that color feature for the landscape. Other varieties or cultivars exhibit the normal green leaf color. Native to northern Europe, the tree was introduced in America in the late 1700s. George Washington reportedly purchased two trees in 1792 to plant at Mount Vernon.

The Purdue Hardwood Tree Improvement and Regeneration Center has signed a commercial partnership agreement with Tree Pro to distribute select hardwood seedlings from its breeding program beginning in March 2025.

The partnership, which will mark the HTIRC’s first commercial release of seedlings in its 25-year history, will see West Lafayette, Ind., based Tree Pro distribute bare root seedlings of six species across its timber select, conservation and wildlife lines. Timber select varieties will include black walnut, black cherry, northern red oak, white oak and pure and hybrid butternut. Conservation species include pure butternut and American chestnut. The wildlife line will feature select precocious white oak.

The HTIRC collection is available for purchase now on the Tree Pro website. Delivery of the seedlings is set for March 2025.

For over five decades, Purdue University and the HTIRC have assembled, tested and selected populations of Indiana’s most valuable hardwood tree species (black cherry, black walnut, northern red oak and white oak) for deployment across the Midwest’s Central Hardwood Forest region. Populations of all four species have been selected for stem straightness and growth rate and are under continuous improvement as breeders remove underperforming clones and seedlings from seed production areas.

Today, as a product of the HTIRC’s efforts, numerous progeny tests, grafted clone banks and orchards exist at Purdue properties across Indiana and are now producing commercial quantities of seed for distribution.  A commercial partnership with Tree Pro now gives the HTIRC an outlet to distribute its hardwood trees to landowners throughout the Central Hardwood Forest Region.

“Tree Pro’s established reputation with conservation groups, private landowners and foresters makes them an ideal distributor of the HTIRC’s select material,” said Matt Ginzel, director of the HTIRC. “We want to make it clear that this partnership will not take away from our existing relationship to provide seeds and seedlings to the Indiana Department of Natural Resources. This simply gives us another avenue to get our material into the hands of the public and to achieve our goal of increasing the value and resilience of woodlands by enriching the diversity of seedlings available for reforestation efforts.”

Tree Pro has been in business for 37 years and is known for its tree protection products (Miracle Tube) and lines of fruit and nut trees oriented to hunters and wildlife enthusiasts.

“When we were approached about the opportunity to distribute genetically diverse select hardwood seedlings from the HTIRC, we were instantly excited,” said Tommy Mills, co-owner of Tree Pro. “It brings our start as a company with black walnuts full circle.”

In addition to making selections on four major hardwood species, the HTIRC has been working to preserve and develop disease-resistant populations of two endangered native fine hardwood species –  butternut and American chestnut.

After more than 20 years of work, the HTIRC now possesses the most diverse collection of butternut in the United States, and has made significant advances in breeding butternuts resistant to the deadly butternut canker fungus. The HTIRC’s canker-resistant butternut program utilizes both pure butternut and hybrids between the butternut (Juglans cinerea) and the Japanese walnut (Juglans ailantifolia), with a program goal of decreasing the proportion of Japanese walnut genetics in the population while increasing overall canker resistance. A collection of pure, disease susceptible butternuts also is maintained for research purposes, and provides valuable seed for organizations and individuals that prefer pure butternut over hybrid butternut.

The American chestnut, once the backbone of timber production for all uses in the eastern United States and a prolific producer of nuts for animals and humans alike, is now functionally extinct due to the accidental introduction of the chestnut blight fungus in 1904. In collaboration with the American Chestnut Foundation and other entities, the HTIRC has assembled an American chestnut collection that represents pure American chestnuts from Indiana and neighboring states. It stands as one of the few grafted American chestnut collections in the country. While currently unavailable for public release, the HTIRC’s ongoing efforts to breed a blight-resistant American chestnut encompasses the use of both interspecific hybrid breeding and biotechnology to restore a long-lost forest species.

“The mother trees for HTIRC’s Timber Select lines were all selected for straight stems with few defects like low forks that can negatively impact standing timber value, while the Timber Select butternuts were selected for their resistance to butternut canker disease,” said Caleb Kell, operational tree breeder for the HTIRC. “Landowners have a good chance of getting similar characteristics out of their seedlings if they are planted on suitable soils with deer protection, which is one of Tree Pro’s specialties.”

Here is a quick list of what is available for purchase:

• HTIRC Timber Select Black Walnut
• HTIRC Timber Select Black Cherry
• HTIRC Timber Select Northern Red Oak
• HTIRC Timber Select White Oak
• HTIRC Timber Select Pure and Hybrid Butternut
• HTIRC Conservation Pure Butternut
• HTIRC Conservation American Chestnut
• HTIRC Wildlife Select Precocious White Oak

Purdue Landscape Report: The bitter winter cold has finally passed us (or has it? It’s hard to tell in the Midwest)! The days are getting warmer and longer, and that means the insects are coming out of their overwintering stages. As you prepare for your landscaping and gardening this year, are you implementing preventative measures for pests? Now is the time to think about those strategies to minimize the damage to your plants.

Preventing pest issues is foundational to integrated pest management. The first step is always to start with healthy and clean plants. Don’t be afraid to bring a hand lens to the store and check for those hard-to-see pests! You don’t want to bring a problem home. Next, remember that many pests will thrive due to improper watering, light conditions, or fertilization. Avoid these issues by reviewing the recommendations for your plants and consulting a soil test. (Read more about why soil tests are essential!)

Finally, which pests/diseases do you anticipate? What are the most common pests on the plants in your landscape? Perhaps you have had issues in past years and know what to expect. Review the biology of these pests and consider implementing preventative measures now. Let’s look at a couple of examples of frequent landscape pests and some management options you can add to your list of spring preparations.

Spider Mites

Spider mites overwinter on the host plant or in leaf litter. Around this time of year, cool season mites such as spruce mites and boxwood mites are the dominant issue. Check your plants now for these spider mites, and scout regularly to make sure populations aren’t getting out of control. A rainy spring will help keep the pressure low. If you have to spray, avoid chemicals that will harm natural enemies, which are vital to spider mite management. (Learn more about spider mite management: Spider Mites on Ornamentals; and check out the Purdue Plant Doctor Quick Guide: Managing Spider Mite Mayhem)

Bagworms

Bagworms overwinter as eggs in the bags left on the tree. They’re frequent pests of arborvitae, junipers, and several other trees and shrubs. Take action now to prevent an infestation in the summer that requires costly pesticides. Manually remove the bags from your tree and drown them in soapy water. (Learn more about bagworm management: Bagworms).

Lace Bugs

Lace bugs may overwinter as eggs or adults, depending on the species. They become active again in the spring, so now is a good time to check for these pests. Focus on the undersides of the leaves where the pests are found. Lace bugs prefer hosts planted in sunny areas with a lack of plant diversity, so consider including some flowering plants in your landscape to provide pollen and nectar to beneficials. (Learn more about Lace bug management from the Purdue Plant Doctor Quick Guide: Managing Lace bugs).

What pests do you encounter in the landscape? Take a moment to review their biology and your options for preventative management. Be proactive now and reduce your pest problems for the season ahead. Read the original article, Insects are waking up – are you prepared?
