Basswood - Characteristics, Benefits and Uses
Tillia, a genus of over 30 species of trees from subfamily Tilioideae is a type of a tree that has originated from
temperate parts of the western and northern hemisphere but has managed to
achieve large diversity in the comparable territories of Asia where most of
the variations of this tree can be found. It is more commonly known in
North America and Europe as basswood, linden and lime tree, even though this
tree has nothing to do with the lime fruit.
On territories where it grows, Basswood managed to become one of the most
common types of trees in nature, which was helped by the ability of this
tree to very easily hybridize, both naturally and in cultivation.
Scientists believe that the official count of over 30 species of Tilia tree
is a conservative number since new hybrids can form and start spreading fairly easily with each passing decade.
Commercial applications of Basswood are numerous, especially for the
application of detailed carving work since the timber of
this tree is especially known to besoft, moldable, with very little grain, low density and easily worked with even most basic carving tools. Since it
is light and does not require a lot of effort for cutting,
it was one of the lumbers of choice for various applications in Europe up
to late medieval times (such as for the creation of lightweight
single-handed wooden shields). Today Basswood timber remains in high demand
not only for the creation of small art and household items
but is also a wood of choice for lightweight window blinds and shutters.
What is Basswood
Basswood is a light, soft and very easily workable type of wood that has
managed to become a lumber of choice for many woodworkers who are
interested to quickly and easily produce lightweight wood products. This odorless and finely grained wood has easily managed to
find its place on the worldwide commercial market, where it is today used
not only for the larger-scale operations such as creation of
wood pulp, veneer, plywood, musical instruments and window shutters and
blinds, but also remains the lumber of choice for woodworkers who wish to carve
objects of all sizes, create small and intricate models, puppets and musical instruments.
In almost all of its types, Basswood is a large deciduous tree that can
easily reach an impressive size of between 20 to 40 meters (65 to 130 ft)
in height, and develop oblique-cordate leaves that can grow in sizes
between 6 to 20 centimeters across. Its flowers are known
to develop in anidentical way for both male and female parts, making this three family hermaphroditic.
If the conditions are right, Tilia/Basswood treescan live exceptionally long, with theoldest surviving trees being claimed to be around 2000 years old.
In addition to producing excellent wood, Basswood also has many other side
benefits, such as medicinal leaves and anexcellent pollen which bees can transform into some of thebest types of honey in the world. Famous Hyblaean Mountains honey is produced using (among
other sources) a large amount of linden trees. Its bark is also known worldwide
for its internal fiber, which can be extracted after keeping bark in water
for a prolonged period of time. Collected fiber can be used for various
purposes, including weaving of clothing.
To this day it is now known where the Tilia tree family originally evolved,
although there were some discoveries that led us closer to the solution of
this mystery. More precisely, the identical fossils of the very old types
of Limewood were found in both Norway and Canada, leading some scientists
to believe that this type of wood is a common ancestor of all Tilia species
in North America and Europe. There is, however, no concrete proof for this
claim, with the entire subfamily of Tilioideae continuing to grow with each
passing decade with the arrival of new hybrids.

Crushing Strength - 4,730 lbf/in2 (32.6 MPa)
Shrinkage - Radial: 6.6%, Tangential: 9.3%, Volumetric: 15.8%, T/R Ratio:
Odor - None, not even during woodworking.
Workability - Very easy, with soft and light wood that can be easily carved
by hand. Finishing, polishing and gluing is possible without any special
treatment of the wood surface. However, it bends poorly using steaming
process and holds nails poorly.
Texture - Nice and even texture with moderate natural luster.
Grain - Very straight and fine grain.
Sustainability - Widespread tree in North America and Europe. Not listed on
the IUCN Red List of Threatened Species.
Required growth density - Prefers rich and well-drained soil and moderate
moisture in the air. It can grow in both shade and sun, but it thrives in
sunlight or partial sunlight.
Drying - Easy and fast.
Durability - Very low in outdoor environments. Rated as non-durable against
normal heartwood decay. Finished Basswood products need to be coated to
survive for decades.
Maintenance - Low after polishing and coating.
Price - Low
Today, after centuries of use for creation of smaller household items, the
use case of this type of wood has shifted into two categories - commercial and small scale. Commercially, Basswood is used
extensively for production of
window shutters and blinds, plywood, veneer, wood pulp and fiber
. On the other hand, woodworkers from all around the world have found
Basswood incredibly suited for the production of intricate
carvings of all sizes, statues, model building, marionette and puppet
. Additionally, since Basswood has great acoustic qualities, it is also extensively used for
the creation of
various wind instruments, recorders, guitar and bass guitar bodies,
recorders, drum shells
, and others. One of the easiest ways to find basswood is in modern
aquariums - air pushed through the basswood grain produces consistently
Here are some of the most popular use case scenarios of Basswood/Tilia/Lime
Marionette and puppet making
Basswood (also known as lime and linden) has more than 30 variations and
hybrids. Here are some of the most common ones:
In addition to producing one of the most used soft lumbers in the wood processing industry,
Basswood is also known for fibers that are hidden in the structure of its
bark. Strong fibers can be extracted from basswood y peeling the outer
layer of bark and keeping it in water for around the month. After that
period of time, fibers will separate one from another, and they can be
harvested and dried up. Archaeologists have found out that clothes made from this fiber were in use in the Bronze age
, and lime tree fiber is also today used for the creation of clothing in Japan.
Flowers of Basswood are also well known for their sweetness. While the
flowers can be used for the creation of tasteful tea, several other parts
of the Basswood tree were found to have various medicinal properties. Wood,
leaves, flowers and wood charcoal all contain various flavonoids
(antioxidants), volatile oils and tannins (which acts as astringent) which
can be beneficial to our metabolism. Home remedies made from Basswood and
other types of Tilia trees are numerous, and can treat the following
High blood pressure
Various respiratory tract conditions
Liver and gallbladder disorders
Edema or skin infections
Ulcers of the lower leg
Possibly has hepatoprotective properties
Finally, the flowers of some double-flowered species of Tillia are used in the creation of perfumes.
