Hartz’s Bluegrass: An Arctic Treasure for Specialized Gardens
If you’re dreaming of bringing a touch of the Arctic to your garden, Hartz’s bluegrass (Poa hartzii hartzii) might catch your attention. But before you start planning, let’s dive into what makes this perennial grass both fascinating and challenging for the average gardener.
What Is Hartz’s Bluegrass?
Hartz’s bluegrass is a perennial grass native to some of the coldest places on Earth – Canada and Greenland. This hardy little survivor belongs to the Poaceae family, making it a true grass rather than a grass-like imposter. It’s named after someone called Hartz (though the historical details are a bit fuzzy), and it’s built to withstand conditions that would make most plants throw in the towel.
Where Does It Call Home?
This arctic specialist has made its home in Quebec, Northwest Territories, and Nunavut – basically, the kinds of places where warm weather means it’s above freezing. It thrives in the extreme northern reaches of North America, where growing seasons are measured in weeks rather than months.
Should You Grow Hartz’s Bluegrass?
Here’s where things get interesting (and potentially disappointing for most gardeners). Hartz’s bluegrass comes with a Global Conservation Status of S3S4T3T4, which indicates it has some conservation concerns. This means if you’re considering growing it, you’ll want to source it responsibly from reputable native plant suppliers – never from wild populations.
But here’s the bigger challenge: unless you live in an arctic or subarctic climate, this grass probably isn’t going to be happy in your garden. It’s evolved for extremely cold conditions and short growing seasons that most of us simply can’t replicate.
Growing Conditions and Care
If you happen to live in USDA hardiness zones 1-3 (the really, really cold ones), you might have a shot at growing Hartz’s bluegrass successfully. This perennial grass likely prefers:
- Extremely cold winters and cool summers
- Well-draining soils that may be rocky or sandy
- Full sun exposure typical of arctic environments
- Minimal competition from other plants
Garden Role and Landscape Use
In its native habitat, Hartz’s bluegrass serves as ground cover in harsh arctic and subarctic landscapes. For the few gardeners who can accommodate its needs, it might work in:
- Alpine or rock gardens in extremely cold climates
- Specialized native plant collections
- Educational or botanical garden displays
Wildlife and Pollinator Value
Like most grasses, Hartz’s bluegrass is wind-pollinated, so it won’t be attracting bees and butterflies to your garden. However, in its native range, it likely provides some habitat and food for arctic wildlife, including small mammals and birds that feed on grass seeds.
The Bottom Line
Hartz’s bluegrass is undoubtedly a remarkable plant – any species that can thrive in arctic conditions deserves our respect. However, it’s not practical for most gardeners due to its extreme climate requirements and conservation status concerns.
If you’re fascinated by cold-climate native grasses but live in a more temperate zone, consider exploring other native grass species that are better suited to your local conditions. Your local native plant society can help you discover beautiful alternatives that will thrive in your specific climate while still supporting local ecosystems.
For those rare gardeners in arctic regions who want to try growing Hartz’s bluegrass, make sure to source plants or seeds from reputable suppliers who can guarantee responsible collection practices. Remember, protecting wild populations is just as important as cultivating garden beauty.
