What Is American Burnweed?

Below are some helpful details about the main characteristics of American burnweed.

  • Habit: This is an annual herb which can extend up to 9 feet in height. It has an erect stem and is more or less strongly ribbed (grooved). It can be simple or branched toward the top and is glabrous to villose, featuring translucent hairs.
  • Leaves: The American burnweed leaves vary in terms of size and shape. The base may differ to a distinct petiole, be broadly sessile or expanded and clasping to auriculate. There are several leaf forms which are often visible on the same plant and those with clasping or auriculate bases are often larger towards the middle of the stem.
  • Length: The American burnweed leaves are alternate. The lower leaves are bigger and can stretch out to 28 cm in width. They are irregularly toothed and lobed with their secondary veins extending to be marginal gland-tipped teeth and the lower leaves being elliptic to broadly lanceolate.
  • Flowers: The upper stems in the plant terminate in panicles of flowerheads. Speaking of, these flowerheads consist of numerous tubular disk florets which are enclosed by green bracts that are smooth and linear. Sometimes, these bracts assume a purplish appearance.
  • Seeds: The dispersal unit of the plant is a cypsela – defined as a unique type of fruit formed from a single seeded inferior ovary. The naked seeds, on the other hand, are mostly dark blue to black with a whitish zone at the base. 
  • Roots: The root system consists of a taproot, featuring shallow and fibrous secondary roots.

The truth is, the American burnweed is a native plant to North America. It has gotten its unique name by being one of the first plants to grow after a fire has burned out an area. Burnweed is also referred to as fireweed – and is also a medicinal plant which is known for some great benefits (more on that below).

How To Identify American Burnweed And Detect Its Habits

The shallow rooted and herbaceous plant grows under a wide range of conditions and disturbed habits. Its stems are brittle and it has large basal leaves as well as deeply serrated upper leaves.

As a relatively benign weed, the American burnweed is prone to removal by hand thanks to its shallow and fibrous roots which are attached to a short taproot. As such, it can produce numerous cup-shaped flowers in the axil and enclose the densely arranged florets in a cylindrical calyx.

When the flowers bloom, they display something like a cluster of silvery hairs attached to tiny seeds. The weed is considered to be native to the forest zones of North America and is known for stretching to 8-10 feet high under its ideal growing conditions.

What Is Am. Burnweed Used For?

As a weed, the American burnweed can compete and interfere with certain crops including blueberries and strawberries, bringing economic losses. It can also reduce the aesthetic attributes of the landscape where it is growing. Even though its scent can be unpleasant to some people, it does not trigger allergies, rashes or other reactions.

What’s interesting is the fact that the American burnweed has a couple of medicinal properties. For example, the oil derived from the plant can be used to treat wounds, hemorrhages, poison ivy rashes as well as other ailments such as piles. The plant is efficient in assimilating atmospheric nitrogen dioxide (which is an important greenhouse gas) and rendering it to its organic form.

Control Of American Burnweed

The american burnweed plant can be easily hand weeded. This is possible because of its relatively shallow root system. Hoeing or cultivation can also help when controlling smaller populations.

The larger populations of the plant can be controlled by applying broadleaf herbicides that contain 2,4-D and triclopyr or other broad-spectrum herbicides. Alternatively, you can use a non-selective herbicide to control American burnweed – glufosinate or glyphosate can work in this manner.

Since American burnweed seeds germinate in thatch, it is difficult to treat them with pre-emergent herbicides. If you want to prevent germination, the best advice is to keep your lawn mowed at a short height below the weed and its growing point. In addition to this, you can apply a post-emergent herbicide to kill the weeds and keep them from producing seeds as well as spreading to other parts of the lawn.
