It is natural to think of spring as the season of flowers in our woodlands, but summer can also provide some outstanding displays of native bloom. In addition, these flowers are often attracting some of our largest and showiest butterflies and bumblebees. Here are a few of the late summer flowers you may encounter in local woodlands. (Click on photos to enlarge.)

Wood Nettle is a look-but-don’t-touch type of plant. While I find the foamy white flowers attractive, the stinging hairs along the stems and under the leaves feel like instant poison ivy. This is one of the reasons Foresters don’t wear short pants in the woods! It is a good indicator of moist and fertile soils.

 

 

 

Wingstem is a large plant with thin ridges along the stems providing the name. These head-high and taller plants of edges, thin woodlands and fertile soils put on a great display. It seems to be a common plant in black walnut plantations as both the good soils and light shade favor its growth.

 

 

 

Tall Bellflower catches the eye as blues seem to stick out in the green and yellow dominated foliage. I see this attractive star-shaped flower on tall stalks at the edge of woodlands and in areas where more sunlight enters the forest understory.

 

 

 

 

Pale or Yellow Jewelweed is in the same genus as the impatiens found in the garden stores. The tube flowers turn into spring-loaded seed pods that pop with the least amount of pressure applied by a finger and thumb. It is hard not to be startled even if you have experienced this mini-explosion before. Spotted Jewelweed is very similar, but has orange flowers with dark dots.

 

 

White Snakeroot can be quite common in forest understories. The white flowers may be the dominant bloom in some woodlands, partly because of the toxic nature of the plant. It is toxic to both livestock and humans and is the source of the milk sickness that killed Abraham Lincolns mother. Cows grazing in woodlands would eat the white snakeroot, which tainted the milk consumed by the pioneer families.

 

 

Jack-in-the-Pulpit flowers in the spring, but the cluster of red berries which ripen in the late summer and fall are large and bright, so they draw attention. While toxic to humans some birds and other wildlife will consume the seeds. The less common, but related Green Dragon plant has similar berry clusters.

Great Blue Lobelia has a name that matches its visual impact. The tall spikes of brilliant blue flowers are excellent for pollinators and put on a great show. This is a plant of woodland edges and moist soils, but can get to be 4 feet tall, with large numbers of flowers, so it is hard to miss when present.

Purdue Landscape Report: Many homeowners have evergreens in their home landscape. Evergreens provide a landscape service that other plants cannot – they add color to our landscapes in the winter, and provide some thermal protection for animals and birds. However, if you are researching potential evergreens for your landscape, you may be confused about species names and the botanical differences between them.

Identifying evergreens is a difficult task for most people, which is why many interchange the terms “evergreen” and “pine tree,” but we can also think of spruces, firs, hemlocks, and other species. Although I encourage planting native trees, I’ll cover several native and non-native evergreen species that may be planted or encountered in Indiana.

Let’s start with the basic aspects of pine trees. Pines have needles that are wrapped together in bundles (called fascicles) of 2, 3, or 5 needles, and their cones hang down from branches. Common 2-needled pines include (from shorter to longer needles) Jack pine, Virginia pine, Scots (or Scotch) pine, Austrian pine, and Red pine. 3-needled pines are somewhat rare in Indiana. Loblolly pine is one, and has very long needles, 6-9 inches long. We have one common 5-needled pine tree, the Eastern white pine.

Purdue Landscape Report: Pollarding is a tree pruning method in which the upper branches of a tree are cut back to the same points on a regular schedule, creating a framework of knobby growth points from which new shoots emerge. The practice has been used for centuries and is especially common in landscapes where trees must be kept at a controlled height or width. Pollarding is not the same as topping, which is generally considered harmful because it removes branches without a long-term management plan. Instead, pollarding is a deliberate, repeated technique that can shape a tree into a compact, manageable form.

One of the main advantages of pollarding is size control. In urban areas, along streets, and near buildings or utility lines, trees often need to fit within tight spaces. Pollarding can reduce conflicts with overhead wires, streetlights, sidewalks, and traffic while still allowing a tree to remain in place. It can also reduce shade, which may be useful in courtyards, parking areas, and other sites where too much canopy cover is a problem. Some trees also respond by producing dense, attractive new growth, which can give them a distinctive architectural look.

Pollarding may also extend the usable life of certain trees when it is started early and maintained properly. Because the tree is kept smaller and more compact, it may be less likely to fail under wind or storm stress than a large tree with heavy limbs. In some settings, the regular cutting of new shoots can even provide a source of small-diameter wood or fodder, which helps explain why pollarding developed historically as a practical land-management method.

That said, pollarding has real drawbacks. It must be done correctly and consistently; if a tree is pollarded at the wrong age, on the wrong species, or after long neglect, the result can be stress, decay, weak regrowth, or structural problems. Not all trees tolerate the practice well, and some may decline if pollarded too aggressively. Pollarding also creates a very artificial appearance, which some people dislike. A freshly pollarded tree can look bare or severe for a time, and the repeated cuts require ongoing maintenance.

Pollarding is most strongly associated with Europe, especially Britain, France, the Netherlands, Italy, and parts of Spain, where it has a long history in both rural and urban landscapes. Today, it is still widely seen in European cities and towns, particularly on street trees and in managed public spaces. It also appears in some parts of North America, but it remains much more culturally visible and historically rooted in Europe. In many places, it is valued both for its practical function and for the distinctive form it creates over time.

Used thoughtfully, pollarding is a useful tool rather than a universal solution. It works best when matched to the right species, the right site, and a long-term maintenance plan. For the right tree in the right place, it can be both functional and visually striking.

Danielle Howard has been hired as an Extension prescribed fire specialist housed with the Department of Forestry and Natural Resources at Purdue

The prescribed fire specialist position, funded by the Sam Shine Foundation, aims to increase prescribed fire capacity in Indiana by coordinating, conducting, and leading prescribed fires and prescribed fire training and outreach statewide.

In this role, Howard also will support the formation of prescribed burn associations (PBAs) and the Indiana Prescribed Fire Council (INPFC). She will work closely with Indiana conservation partners to develop prescribed fire training and outreach that builds capacity and support for prescribed fire on public and private land in Indiana.

“Prescribed fire is key to maintaining healthy ecosystems in Indiana, and I’m very excited to be at the forefront of increasing its use across the state,” Howard said.

Co-PIs on the supporting grant titled “Building Capacity for Prescribed Fire in Indiana” are Extension wildlife specialists Jarred Brooke and Brian MacGowan, Extension forester Lenny Farlee, natural resources training specialist Jessica Outcalt and Dr. Zhao Ma.

Howard, who previously worked in FNR as the field coordinator for the Hardwood Ecosystem Experiment from 2020 to 2023, comes to her new role after spending the last three years as the central region ecologist for the Indiana Department of Natural Resources Division of Fish, Wildlife and Nature Preserves. In that role, she managed 71 state-dedicated nature preserves and multiple privately-owned conservation easements across 26 counties in central Indiana. She also planned, prepared and implemented prescribed fire, invasive species control measures, native plantings, forest stand management and other restoration activities. She also established and sampled research plots for post-fire vegetation monitoring in Brown County State Park.

Howard also has taught Applied Ecology as an adjunct professor at Indiana University since January 2025.

In her previous stint in FNR as part of the HEE project, Howard coordinated forest management research activities, including bird surveys, overstory plots, small mammal trapping and more, conducted by various universities and partners at sites in Morgan-Monroe and Yellowwood State Forests.

Previously, she acted as an intermittent bird biologist for the Indiana DNR, the whooping crane outreach program assistant in Indiana for the International Crane Foundation and as a farm bill wildlife biologist for Pheasants Forever/Quail Forever.

Howard is a type II certified wildland firefighter and has certifications in prescribed fire for managers, wildlife fire chainsaws (S-212), wildlife fire pumps (S-211) and a pesticide applicator’s license for core and forests.

Howard began her new role on May 18. She will be based remotely in Bloomington, Indiana.

Entomology Weekly Review: Purdue Forestry & Natural Resources (FNR) Extension would like to share a timely update from the Indiana Department of Natural Resources – Division of Entomology newsletter regarding a wood-boring insect that may be encountered in hardwood logs across the state. Will Drews, Entomology staff member located in south-central Indiana (Bloomington area), recently reported activity from one of the more common round-headed borer pests found in hardwood logs: the flat-faced longhorn beetle, Graphisurus fasciatus. Will shares in the Entomology Weekly Review how to identify the borer, their habitat and if we need to be concerned.

What to Look For
On the wing recently is one of the more common round-headed borer pests I find in hardwood logs, and that is the flat-faced longhorn beetle without a common name: Graphisurus fasciatus (Photos 2 – 5).  This longhorn beetle (in the family Cerambycidae) is quite large as far as longhorn beetles go, reaching up to 0.6 inches in length, and features two long antennae (aka “horns”) characteristic of most of its family (Photo 3).

Host Trees and Habitat
As a larva, Graphisurus fasciatus feeds on a variety of hardwoods and is reported to feed on pine trees as well. I generally find G. fasciatus larvae feeding between
the bark and sapwood of black walnut (Juglans nigra), white oak (Quercus alba ) and red oak (Quercus rubra) logs (Photo 6).

Identification Tips
There are several ways to differentiate this species from the less common but closely related Graphisurus despectus, but one of the surest ways is to examine the scutellum (aka the small shield-like plate at the top/between the elytra [wing covers]). In G. fasciatus, the scutellum has two small whitish patches of hair, not present on G. despectus (Photo 7). Another diagnostic characteristic of G. fasciatus is that it has elytra with emarginate (or notched) tips (Photo 8).

Should You Be Concerned?
This species can be alarming by its noticeable size and relative abundance but is not necessarily a major pest of concern as it does not usually bore into the sapwood and cause defects to the wood.

Stay Informed
FNR Extension encourages landowners and natural resource professionals to remain observant when working with hardwood logs and report unusual insect activity when found.

To stay up to date on forest health and insect alerts, consider subscribing to the  Indiana Department of Natural Resources – Entomology Weekly Review for regular updates on insects affecting Indiana’s forests and natural areas.
