The seaside juniper (Juniperus maritima) is a special type of juniper tree. It grows naturally only in the Puget Sound area. This area is found in southwestern British Columbia (Canada) and northwestern Washington (USA).
This tree is called "seaside juniper" because it loves to grow near the water. You can find it on coastal cliffs and even on dry mountain ridges on the Olympic Peninsula. It's a unique plant that only lives in this specific region.

What Makes the Seaside Juniper Special?
For a long time, scientists thought the seaside juniper was the same as the Rocky Mountain juniper (Juniperus scopulorum). But in 2007, they found out it was different!
How Scientists Discovered a New Species
Scientists used something called genetic analysis to study the trees. This is like looking at the tree's DNA. They found that the junipers in the Puget Sound area had different DNA from the Rocky Mountain junipers found elsewhere. This was a big clue!
Physical Differences in the Tree
The seaside juniper also looks a bit different. Scientists call these differences "morphology". For example, its cones (which hold the seeds) grow faster. The seeds inside the cones also stick out more. These small differences helped scientists see that it was a separate species.
Unique Home of the Seaside Juniper
One of the most interesting things about the seaside juniper is where it lives. It grows right next to the water, like the Puget Sound or nearby lakes. It prefers a milder, wetter climate. It also likes sandy soils, even sand dunes in some places.
How It Differs from Rocky Mountain Juniper's Home
The Rocky Mountain juniper, on the other hand, lives in very different places. It grows in drier, rockier areas. These places are usually much colder and higher up in the mountains. This big difference in habitat is another reason why the seaside juniper is its own species.
Reproduction and No Interbreeding
The seaside juniper also reproduces on its own. It does not mix or "interbreed" with other types of junipers. This is more proof that it is a distinct species. It keeps its unique traits because it only reproduces with other seaside junipers.
Is the Seaside Juniper Safe?
Generally, there are many seaside junipers in their native home. They are common to abundant. However, they do face some challenges.
Challenges for the Seaside Juniper
- Development: Sometimes, new buildings or towns are built where these trees grow. This is called development. It can take away their natural habitat.
- Competition: The seaside juniper can also have to compete for space and sunlight. Another tree, the Douglas-fir, sometimes grows nearby. The Douglas-fir can grow very tall and block the sun from the smaller junipers.
Despite these challenges, the seaside juniper continues to thrive in its special Puget Sound home.
