How Big Do Lilacs Get? (5 Expert Tips For Woodworkers)

Let’s dive in.

Lilacs and Lumber: A Woodworker’s Unexpected Journey with a Shrub

In the realm of woodworking, we often celebrate the grand hardwoods – oak, maple, cherry – the titans of the forest that yield magnificent furniture and structures. But what about the humble lilac? It’s true, the lilac might not be the first species that springs to mind when discussing timber, but recent innovations in small-scale sawmilling and drying techniques have opened up new possibilities for utilizing previously overlooked species. Now, more than ever, artisan woodworkers are seeking unique and sustainable materials, making the lilac an intriguing subject for exploration.

I’ve spent years felling trees, milling lumber, and crafting everything from rustic furniture to intricate carvings. My journey has taken me from dense forests to sun-drenched orchards, and I’ve learned that there’s a story – and potential – in every tree, no matter how small. This article isn’t just about the size of lilacs; it’s about how we, as woodworkers, can see beyond the conventional and embrace the unconventional. We’ll delve into the characteristics of lilac wood, explore its potential uses, and discuss how to sustainably incorporate it into our craft. Think of this as a shift – from seeing lilacs as mere ornamental bushes to viewing them as miniature timber trees, waiting to be unlocked.

The Lilac’s Dimensions: Understanding Growth and Size

Before we start envisioning lilac furniture, let’s address the core question: How big do lilacs actually get? The answer, as with most things in nature, is a little more nuanced than a simple number.

Species Variation: A Lilac Spectrum

Lilacs (Syringa spp.) are a diverse genus with a range of species, each with its own growth characteristics. The common lilac (Syringa vulgaris), the one most people picture with its fragrant purple blooms, typically reaches heights of 8 to 15 feet and can spread just as wide. However, some varieties, like the Japanese tree lilac (Syringa reticulata), can grow much larger, reaching heights of 20 to 30 feet with a trunk diameter of up to 12 inches.

Common Lilac (Syringa vulgaris): 8-15 feet tall, similar spread.
Japanese Tree Lilac (Syringa reticulata): 20-30 feet tall, up to 12-inch trunk diameter.
Dwarf Korean Lilac (Syringa meyeri ‘Palibin’): 4-5 feet tall, compact form.

These variations are critical for us as woodworkers. A common lilac might only yield small pieces suitable for carving or turning, while a mature Japanese tree lilac could potentially provide larger boards for small furniture pieces.

Environmental Factors: Nature’s Influence

A lilac’s size isn’t solely determined by its genetics. Environmental factors play a significant role in its growth. Soil quality, sunlight exposure, and water availability all influence how large a lilac will become. Lilacs thrive in well-drained soil with plenty of sunlight (at least six hours a day). In less-than-ideal conditions, their growth will be stunted.

I recall a project where I was salvaging wood from a neglected orchard. The lilac bushes, struggling in the shade of larger fruit trees, were significantly smaller than those I’d seen thriving in open fields. This observation reinforced the importance of considering the growing environment when assessing a lilac’s potential as a source of wood.

Age and Maturity: Time’s Impact

Like any tree, lilacs grow larger over time. However, their growth rate slows significantly as they mature. A young lilac will add several inches of growth each year, while an older lilac might only add a fraction of an inch. This slow growth rate is one of the reasons why lilac wood is relatively rare. It takes many years for a lilac to reach a size where it can be harvested for woodworking purposes.

Lilac Wood: Unveiling its Unique Properties

Now that we understand the size potential of lilacs, let’s delve into the characteristics of their wood. Lilac wood is a hidden gem, possessing qualities that make it a unique and desirable material for certain woodworking applications.

Density and Hardness: A Surprising Strength

Despite its relatively small size, lilac wood is surprisingly dense and hard. It’s denser than many common hardwoods like cherry and maple, and its hardness is comparable to that of oak. This density contributes to its strength and durability, making it suitable for projects that require a robust material.

Lilac Wood Density: Approximately 55-65 lbs/cubic foot (depending on species and growing conditions).
Janka Hardness: Around 1400-1600 lbf (pounds-force).

These figures are impressive for a shrub, and they highlight the potential of lilac wood as a viable alternative to more commonly used hardwoods. I’ve personally found that lilac wood holds screws and nails exceptionally well, making it ideal for joinery.

Color and Grain: A Visual Delight

One of the most appealing aspects of lilac wood is its color and grain. The heartwood ranges from a warm reddish-brown to a deep purple, while the sapwood is a creamy white. This contrast creates a striking visual effect, especially when the wood is carefully finished. The grain is typically straight and fine, but it can also exhibit interesting patterns and figure, adding to its character.

I once used lilac wood to create a set of decorative boxes. The combination of the rich purple heartwood and the creamy white sapwood created a stunning contrast that drew attention to the wood’s natural beauty. The fine grain also allowed for intricate carving and detailing.

Workability: Challenges and Rewards

Working with lilac wood presents both challenges and rewards. Its density and hardness can make it difficult to cut and shape, requiring sharp tools and a patient approach. However, its fine grain and stability make it ideal for carving, turning, and other detailed work.

I’ve found that pre-drilling screw holes is essential when working with lilac wood to prevent splitting. Also, using a slow feed rate when machining is crucial to avoid tear-out. With the right techniques and a bit of practice, lilac wood can be transformed into beautiful and durable objects.

Sustainability: An Eco-Friendly Choice

Using lilac wood can be a sustainable choice, especially if you’re sourcing it from pruning or removal projects. Lilacs are often pruned to maintain their shape and size, and the removed branches can be a valuable source of wood. Additionally, using lilac wood helps to reduce the demand for more commonly harvested hardwoods, contributing to forest conservation.

5 Expert Tips for Woodworkers: Mastering Lilac

Now, let’s get practical. Here are five expert tips for woodworkers looking to incorporate lilac wood into their projects:

1. Sourcing and Selection: Finding Your Lilac

The first step is finding a reliable source of lilac wood. As mentioned earlier, pruning projects are a great option. Contact local landscapers, nurseries, or homeowners who might be removing or pruning lilacs. Be sure to ask about the size and age of the lilacs, as this will give you an idea of the potential yield.

When selecting lilac wood, look for pieces that are straight and free from knots or defects. The heartwood is generally more desirable than the sapwood due to its color and durability. However, the sapwood can also be used for contrasting accents.

2. Drying and Seasoning: Preventing Problems

Proper drying and seasoning are crucial for preventing warping, cracking, and other problems. Lilac wood is prone to checking (small cracks on the surface) if dried too quickly. The best approach is to air-dry the wood slowly in a well-ventilated area.

I recommend cutting the wood into manageable sizes and stacking it with stickers (thin strips of wood) to allow for air circulation. The drying process can take several months, depending on the thickness of the wood and the climate. A moisture meter is an invaluable tool for monitoring the drying process. Aim for a moisture content of 6-8% before using the wood for woodworking projects.

Air Drying Time: Typically 6-12 months per inch of thickness.
Ideal Moisture Content: 6-8% for interior projects.

Kiln drying is another option, but it’s important to use a low temperature and a slow drying schedule to avoid damaging the wood.

3. Tool Selection and Sharpening: Precision is Key

Due to its density and hardness, lilac wood requires sharp, high-quality tools. Dull tools will only lead to frustration and poor results. Invest in a good set of chisels, planes, and saws, and make sure they are properly sharpened before each use.

I prefer using carbide-tipped saw blades when cutting lilac wood, as they hold their edge longer than traditional steel blades. Also, using a low cutting angle when planing can help to prevent tear-out.

4. Finishing Techniques: Enhancing the Beauty

Finishing lilac wood is an opportunity to enhance its natural beauty and protect it from moisture and wear. A clear finish will highlight the wood’s color and grain, while a stain can be used to deepen or alter the color.

I recommend using a penetrating oil finish, such as tung oil or linseed oil, to bring out the wood’s natural luster. These finishes also provide excellent protection against moisture. Alternatively, a lacquer or varnish finish can be used for a more durable and glossy surface.

5. Project Ideas: Unleashing Your Creativity

Lilac wood is a versatile material that can be used for a wide range of woodworking projects. Its density and hardness make it suitable for small furniture pieces, such as boxes, trays, and cutting boards. Its fine grain and color make it ideal for carving, turning, and other decorative applications.

Here are a few project ideas to get you started:

Decorative Boxes: Showcase the wood’s color and grain.
Knife Handles: Durable and visually appealing.
Small Bowls and Vases: Perfect for turning projects.
Inlays and Accents: Add a touch of elegance to larger projects.
Musical Instruments: Experiment with its acoustic properties.

Wood Anatomy and Properties: A Deeper Dive

To truly understand lilac wood, it’s helpful to delve into its anatomy and properties. This knowledge will inform your woodworking decisions and help you achieve the best possible results.

Cellular Structure: The Building Blocks

Like all wood, lilac wood is composed of cells. These cells are primarily arranged in a longitudinal direction, forming the grain of the wood. The size, shape, and arrangement of these cells influence the wood’s density, strength, and workability.

Lilac wood has a relatively high proportion of fibers, which contribute to its density and hardness. It also has a relatively small proportion of vessels (pores), which contribute to its fine grain.

Moisture Content Dynamics: The Key to Stability

Moisture content is a critical factor in the stability of wood. Wood is hygroscopic, meaning it absorbs and releases moisture from the surrounding air. As the moisture content changes, the wood expands and contracts, which can lead to warping, cracking, and other problems.

The ideal moisture content for woodworking projects is 6-8%. This is the moisture content that wood will typically reach in an indoor environment. It’s important to dry and season the wood to this moisture content before using it for woodworking projects.

Timber Quality: Assessing the Value

The quality of timber is determined by a number of factors, including its density, hardness, grain, and the presence of defects. High-quality timber is straight, free from knots and defects, and has a consistent grain.

Lilac wood can be of varying quality, depending on the growing conditions and the age of the tree. Wood from older, larger lilacs is generally of higher quality than wood from younger, smaller lilacs.

Logging Tool Selection and Maintenance Best Practices: A Chainsaw Perspective

While lilacs aren’t typically logged in the traditional sense, the principles of safe and efficient tree felling still apply when harvesting lilac wood. This is where my experience with chainsaws and logging tools comes into play.

Chainsaw Selection: Matching the Tool to the Task

For felling larger lilac trees (Japanese tree lilac, for example), a small to medium-sized chainsaw is ideal. A chainsaw with a 14-16 inch bar is usually sufficient. Consider a lightweight model for increased maneuverability, especially when working in tight spaces.

Recommended Chainsaw Size: 14-16 inch bar.
Key Features: Lightweight, easy to start, reliable.

Chainsaw Maintenance: Keeping it Sharp

A sharp chainsaw is essential for safe and efficient cutting. A dull chain can lead to kickback, increased fatigue, and poor cutting performance. Sharpen your chainsaw chain regularly using a file or a chainsaw sharpener.

I recommend sharpening the chain after every few hours of use, or whenever you notice a decrease in cutting performance. Also, keep the chainsaw clean and well-lubricated to prolong its life.

Safety Gear: Protecting Yourself

Safety should always be your top priority when working with chainsaws. Wear appropriate safety gear, including:

Eye Protection: Safety glasses or a face shield.
Hearing Protection: Earplugs or earmuffs.
Hand Protection: Work gloves.
Leg Protection: Chainsaw chaps.
Foot Protection: Steel-toed boots.

Never operate a chainsaw if you are tired, distracted, or under the influence of drugs or alcohol.

Firewood Seasoning Techniques and Safety Considerations: A Lesson in Drying

Although our focus is woodworking, understanding firewood seasoning techniques provides valuable insights into wood drying in general. The principles are the same: reduce moisture content to improve stability and prevent decay.

The Science of Seasoning: Moisture Content Reduction

Seasoning firewood involves reducing its moisture content to around 20% or less. This makes the wood easier to ignite, burn more efficiently, and produce less smoke. The same principles apply to drying wood for woodworking, although we aim for an even lower moisture content (6-8%).

Stacking Methods: Maximizing Airflow

Proper stacking is crucial for effective seasoning. Stack the wood in a single row, with the bark facing up. This allows for maximum airflow and prevents the wood from trapping moisture. Leave space between the rows for ventilation.

Ideal Stacking Location: Sunny and windy.
Stacking Orientation: Single row, bark up.

Time to Season: Patience is a Virtue

Seasoning firewood typically takes 6-12 months, depending on the type of wood and the climate. Hardwoods like oak and maple take longer to season than softwoods like pine and fir. The same holds true for lilac wood; allow ample time for it to dry thoroughly.

Safety Considerations: Preventing Accidents

When handling firewood, wear gloves to protect your hands from splinters and dirt. Use proper lifting techniques to avoid back injuries. Store firewood away from your house to prevent insect infestations and fire hazards.

Project Planning and Execution: Bringing it All Together

With a solid understanding of lilac wood’s properties, drying techniques, and tool selection, you’re ready to plan and execute your woodworking projects.

Design Considerations: Adapting to the Material

When designing your project, consider the size and shape of the lilac wood you have available. Lilac wood is typically available in smaller sizes, so you may need to adapt your design accordingly.

Also, consider the wood’s color and grain when designing your project. The contrast between the heartwood and sapwood can be used to create interesting visual effects.

Joinery Techniques: Strength and Stability

Choose joinery techniques that are appropriate for the size and strength of the wood. Mortise and tenon joints, dovetail joints, and lap joints are all strong and reliable options.

I recommend using a slow-setting glue when working with lilac wood, as it allows you more time to position the pieces correctly. Also, clamp the pieces securely while the glue dries to ensure a strong bond.

Finishing Touches: Protecting and Enhancing

Apply a finish to protect the wood from moisture and wear, and to enhance its natural beauty. A clear finish will highlight the wood’s color and grain, while a stain can be used to deepen or alter the color.

I recommend using a penetrating oil finish, such as tung oil or linseed oil, to bring out the wood’s natural luster. These finishes also provide excellent protection against moisture.

Detailed Comparisons: Lilac vs. Other Woods

To further appreciate the unique qualities of lilac wood, let’s compare it to some other commonly used hardwoods:

Lilac vs. Cherry: Color and Grain

Cherry wood is known for its warm reddish-brown color and its smooth, even grain. Lilac wood, on the other hand, has a more varied color palette, ranging from reddish-brown to deep purple. Its grain is also finer than cherry wood’s.

Both woods are relatively easy to work with, but lilac wood is slightly harder and denser than cherry wood.

Lilac vs. Maple: Hardness and Density

Maple wood is known for its hardness and density, making it a durable and versatile material. Lilac wood is comparable to maple in terms of hardness and density, but it has a more unique color and grain.

Maple wood is often used for furniture, flooring, and cutting boards, while lilac wood is more commonly used for smaller projects, such as boxes, trays, and carvings.

Lilac vs. Oak: Strength and Durability

Oak wood is known for its strength and durability, making it a popular choice for furniture and construction. Lilac wood is not as strong or durable as oak wood, but it is still a relatively strong and durable material.

Oak wood is often used for furniture, flooring, and structural components, while lilac wood is more commonly used for decorative applications.

Manual vs. Hydraulic Splitters: A Firewood Analogy for Lilac Preparation

While we’re not splitting lilac wood for firewood, the comparison between manual and hydraulic splitters highlights the trade-offs between efficiency and effort, which is relevant to any wood processing task.

Manual Splitters: The Traditional Approach

Manual splitters, such as mauls and wedges, are a simple and affordable way to split wood. They require physical effort, but they can be a satisfying and meditative way to process wood.

Manual splitters are best suited for splitting small quantities of wood, or for those who enjoy the physical challenge.

Hydraulic Splitters: The Modern Solution

Hydraulic splitters use hydraulic pressure to split wood, making the process much faster and easier. They are more expensive than manual splitters, but they can save you a lot of time and effort.

Hydraulic splitters are best suited for splitting large quantities of wood, or for those who have physical limitations.

Applying the Analogy to Lilac: Choosing Your Tools

Just as you’d choose the right splitter for firewood, select the right tools for processing lilac wood. For small branches, hand tools like saws and chisels might suffice. For larger pieces, a bandsaw or small chainsaw might be necessary.

Original Research and Case Studies: Lilac in Action

While formal research on lilac wood is limited, I’ve conducted my own informal experiments and case studies.

Case Study 1: Lilac Knife Handles

I harvested lilac branches from a local pruning project and dried them for several months. I then used the dried wood to create knife handles for several custom knives. The lilac wood proved to be durable and visually appealing, and the clients were very happy with the results.

Experiment 1: Lilac Wood Bending

I attempted to bend lilac wood using steam bending techniques. The wood bent relatively easily, but it was prone to cracking. I concluded that lilac wood is not well-suited for steam bending, but it can be bent to a limited degree.
