Swamp-dweller, water-lover. The wood of this tough tree doesn’t rot when waterlogged, instead turning stronger and harder.
Look for the leaf tip of alder trees – its never pointed and usually rounded or even indented.
The seeds develop in woody cone-like fruits which often hang around on the tree throughout the winter and into the next growing season.
Conical in shape, mature trees can reach a height of around 28m and live to approximately 60 years.
The bark is dark and fissured and is often covered in lichen. Twigs have a light brown, spotted stem which turns red towards the top. Young twigs are sticky to touch.
Look out for: small brown cones, which are the female catkins and stay on the tree all year round.
Identified in winter by: female catkins (that look a bit like cones) and purple twigs with orange markings (known as lenticels).
Alder trees are common deciduous trees found throughout the Northern Hemisphere With their rapid growth and adaptability to various soil conditions, alders play an important role in their ecosystems Alders can also be an attractive addition to landscapes and parks. Their striking shapes and textures make them great subjects for photographers. Here’s a guide to capturing the beauty of alder trees in pictures.
Getting to Know the Alder
There are around 35 species of alder worldwide. Alders are members of the birch family Betulaceae They are closely related to birches, hazels, and hornbeams. Alders are medium-sized trees reaching heights of 40-80 feet. Their leaves are alternate, simple, and toothed The leaves are oval, elliptical or round.
The most distinctive feature of alders are their catkins. Both male and female flowers emerge as catkins in early spring before the leaves. The male catkins are long and pendulous, turning yellow with pollen. The female catkins are much smaller and purple, maturing into woody cones containing seeds.
Alders thrive in moist areas along river banks, streams, lakes, and wetlands. They also tolerate flooding and poorly drained soils. Their roots have nodules that fix nitrogen, allowing alders to colonize disturbed sites and enrich the soil for other plants.
Some popular alder species photographed include:
-
Black alder – Common in Europe, northern Africa, and western Asia. Has dark gray fissured bark.
-
Red alder – Native to the Pacific Northwest coast of North America. Important hardwood used for making guitars.
-
White alder – Fast growing tree reaching 100 feet tall. Found along streams in western North America.
-
Green alder – Shrubby species with glossy yellow-green leaves found across the Northern Hemisphere.
Capturing the Alders’ Distinctive Features
When photographing alder trees, focus on capturing their unique identifying features:
Trunks and Branches: The trunks and branches of alders form striking gnarled shapes and twisting patterns. Look for curved or swooping lines that make a dynamic composition. Capture the corky or warty texture of the bark.
Leaves: Shoot leaves backlit by the sun to emphasize their toothed margins and venation. Try photographing the leaves in spring as they emerge with a fresh yellow-green color.
Catkins: Close-ups of the long dangling male catkins make excellent photos. Capture them trembling in the breeze. For female catkins, focus on their petite size and purple color.
Cones: The mature woody cones can remain on the branches for months, adding texture. Compose them together with leaves or catkins.
Wetland Settings: Shoot wide landscape scenes showcasing alders in their natural wetland habitat. Position alders in the foreground with water or marsh plants in the background.
Groups: The narrow, vertical form of alders makes them ideal subjects for grouping together. Photograph stands or thickets of alders to emphasize repetitive patterns.
Tips for Photographing Alders
Here are some tips to follow when photographing alder trees:
-
Shoot in bright overcast conditions for ideal even lighting. Avoid direct sunlight which creates harsh shadows.
-
Use a polarizing filter to cut glare and saturate colors when shooting foliage or catkins.
-
Stop down the aperture to widen the depth of field. Keep all parts of the alder foliage or catkins in focus.
-
Adjust your composition to utilize leading lines, symmetry, rule of thirds, and other elements.
-
Focus stack multiple exposures to maximize depth of field for landscape scenes.
-
Use a tripod for stability when shooting in low light or for macro photography.
-
Photograph catkins or new leaves in springtime as they emerge. Capture fall foliage color, though limited compared to other species.
-
Shoot in fog to create a moody, mystical atmosphere around the alders.
-
Include alder leaves, catkins, or cones in nature tabletop scenes.
Creative Ways to Photograph Alders
Looking to capture alders in a creative way? Try these photographic techniques:
-
Silhouettes – Photograph alders as silhouettes against a bright sky at sunset or sunrise. Emphasize their jagged shapes.
-
Black & White – Convert images to black and white to focus on the alders’ texture and form.
-
Macro – Get an intimate look at catkins, leaves, bark or cones by filling the frame in close-up macro shots.
-
Reflections – Compose striking mirror-image reflections of alders in calm waters.
-
Motion Blur – Use slow shutter speeds to create an energetic sense of motion with wind-blown branches.
-
Framing – Frame views of alders using openings in fences or other foreground objects.
-
Seasonal Changes – Document the life cycle of alders through the seasons, from spring buds to winter silhouettes.
For photographers looking to capture beautiful trees filled with visual interest, alders make excellent subjects. Pay attention to their distinctive catkins, leaves, bark, and wetland settings. Use lighting, composition, and creative techniques to photograph them in an artistic way. Patiently wait for the perfect moment to showcase the allure of the humble alder tree.
Watch alder leaves budding
Hazel (Corylus avellana). The rounded leaf shapes are similar, but hazel leaves are softly hairy compared to the shiny ones of alder.

Alder is the only British native deciduous tree to develop cones.
What does alder look like?

The purple or grey leaf buds form on long stems and the 3–9cm long, dark green leaves are racquet-shaped and leathery, with serrated edges. The leaf tip is never pointed and is often indented.

Flowers are on catkins which appear between February and April. Alder is monoecious, which means that both male and female flowers are found on the same tree. Male catkins are pendulous, measuring 2–6cm, and turn yellow. Female catkins are green and oval-shaped and are grouped in numbers of three to eight on each stalk.

Once pollinated by wind, the female catkins gradually become woody and appear as tiny, cone-like fruits in winter. They open up to release their seeds, which are dispersed by wind and water.

FAQ
What is special about alder trees?
Soft and porous, alder wood is only durable if kept wet, and its value to humans is down to its ability to withstand rotting in water. Historically, it has been used in the construction of boats, sluice gates and water pipes. These days, alder wood is used to make timber veneers, pulp and plywood.
What states do alder trees grow in?
White alders grow along streamsides or just adjacent to them on the dryer, rocky slopes above. Occupying a wide elevational range, they occur from just above sea level to almost 2400 m (8000 ft), primarily in California, Oregon, Washington, Idaho, and Montana.
What is another name for the alder tree?
The Alder tree, scientifically known as Alnus, is a remarkable species found in various regions around the world, including North America, Europe, and Asia.
Is alder tree the same as elder tree?
Elder is a deciduous shrub that can grow up to 10 metres tall. It has large flat clusters of white flowers in June and July, followed by purplish-black elderberries that ripen in August and September. 2. The elder should not be confused with the alder (a tree of damp conditions).
