If you are a woodworking beginner, it’s easy to get lost and overwhelmed because of the options to choose from. Why are some hardwoods soft, and why are some softwoods hard? What is the best lumber for the job? 

Worry not, for we have compiled a guide to answer your questions on whether or not poplar is a hardwood.

What Kind of Wood is Poplar?

Poplar is usually mistaken for softwood because its hardness resembles pine or cedar. 

However, it has a finer grain and a more pronounced wood pattern than coarsely-grained softwoods. It is usually used as material for furniture making, such as frames for cabinets, dressers, and panels.

But to set things straight, poplar is a hardwood. It comes from a deciduous tree and is not evergreen like coniferous softwoods. Contrary to its name, it does not belong to the Populus genus.

Instead, it is from the Liriodendron genus and is a dioecious plant, which means that male and female flowers are grown on separate plants, and the wind later pollinates the seeds.

In terms of hardness, it scores a bit higher than some soft wood variants like white pine but is well below most hardwood types. This ranks it as one of the softest hardwoods on the Janka Scale.

Poplar Wood Hardness in the Janka Scale

To better grasp the hardness rating, we recommend the Janka Scale. It is a standard measurement used in the production industry.

The higher the number is on the scale, the harder the lumber is. For reference, common poplars sit at around 540 pound-force (lbf) [1], and below are some of the Janka numbers for other common woods:

What is Poplar Used For?

Poplars are usually used as framing for furniture hidden by upholstery. The most common is frames for cabinets and dressers that are later finished with plywood or other hardwoods for their exterior. 

It is also used for making pallets, shipping crates, and other utility equipment that bank on strength and durability rather than appearance.

Unlike most hardwoods, it is not known for its overall aesthetic. However, certain species like rainbow poplar have a good variety of hues when stained or exposed under the sun for some time. Woodturners use them to make plates, bowls, and other artisanal merchandise.

Projects Using Poplar Wood

You might be wondering which woodwork projects is poplar good for. Seasoned woodworkers use it for cabinets, toys, and wood turnings because it is easy to work with and highly affordable. 

Poplar wood furniture is the usual pick because it holds nails, screws, glue, and even paint well. It has a straight, muted grain and a cream to yellowish-brown color, making it ideal for cabinetry and interior trim. Its low density and porosity, however, make it hard to sand.

Poplar Wood in the Yard

What is quite confusing about poplars is that their scientific classification is split in two. “True” poplars belong to the genus Populus, which includes aspens and cottonwoods, while common yellow poplar belongs to the genus Liriodendron.

As a yard tree, true poplars are tough and easy to grow. They are tall and upright, and their leaves change with the season.

Once they mature, they have an impressive landscape appearance. Its aggressive root system needs usual tending as it can crowd out other plants in the area and even reach sewer and pipelines if left unmaintained.

During autumn, the female poplars produce many fluffy seeds that can litter the yard. If you have no time to look after them, it is best to get a male variety.
