Seaside Juniper: A Rare Pacific Northwest Native Worth Protecting
Meet the seaside juniper (Juniperus maritima), a mysterious and rare coniferous tree that calls the Pacific Northwest coast home. If you’ve never heard of this native beauty, you’re not alone – this juniper is one of those special plants that flies under the radar, quietly growing in its coastal habitat while most of us are none the wiser.
What is Seaside Juniper?
Seaside juniper is a perennial, woody tree that typically reaches impressive heights of 13 to 16 feet or more, though environmental conditions can sometimes keep it shorter and more shrub-like. As a member of the juniper family, it’s an evergreen conifer that adds year-round structure and greenery to the landscape.
Where Does It Grow?
This native tree has a surprisingly limited range, naturally occurring only in British Columbia, Canada, and Washington State. Its coastal distribution suggests it’s perfectly adapted to the unique conditions found along the Pacific Northwest shoreline.

A Rare Gem That Needs Our Attention
Here’s where things get important for any gardener considering this plant: seaside juniper has a Global Conservation Status of S3S4, indicating it’s uncommon to fairly common but still faces some level of conservation concern. This rarity status means we need to be thoughtful about how we approach growing this species.
If you’re interested in adding seaside juniper to your garden, here’s what you need to know:
- Only source plants from reputable native plant nurseries
- Ensure any plants you purchase are ethically propagated, not wild-collected
- Consider this species only if you’re in its native range or similar coastal conditions
- Verify the plant identification, as maritime junipers can be easily confused with other coastal conifers
Is Seaside Juniper Right for Your Garden?
Given the limited information available about this rare species and its conservation status, seaside juniper isn’t a plant for every gardener. However, if you live within its native range and can source it responsibly, it could be a meaningful addition to a native plant collection or coastal restoration project.
Since specific growing requirements for this species are not well-documented, your best bet is to:
- Consult with local native plant societies
- Contact botanical gardens or universities in the Pacific Northwest
- Work with conservation organizations familiar with coastal ecosystems
Supporting Native Plant Conservation
Whether or not you end up growing seaside juniper, its story reminds us of the importance of protecting our native plant heritage. Many of our regional natives face similar challenges, and supporting conservation efforts, choosing responsibly sourced plants, and creating habitat in our own yards all make a difference.
If seaside juniper proves too elusive or challenging for your garden, consider other Pacific Northwest natives like shore pine, Pacific madrone, or more common juniper species that can provide similar evergreen structure while being easier to source and grow successfully.
