The Elusive Intermediate Dogwood: A Northern Native Worth Knowing
Meet Cornus ×intermedia, a rather mysterious member of the dogwood family that calls the far northern reaches of North America home. While most gardeners are familiar with the flashy flowering dogwoods of temperate regions, this particular dogwood marches to the beat of its own drum – and it’s a pretty quiet beat at that!
What Makes This Dogwood Different
The × in Cornus ×intermedia isn’t a typo – it’s botanical shorthand telling us this is a natural hybrid. Think of it as nature’s own plant breeding experiment, combining the best (and sometimes most confusing) traits of its parent species. This little-known dogwood is a true native to some pretty impressive places: Alaska, various provinces in Canada, Greenland, and even St. Pierre and Miquelon.
Where You’ll Find It Growing Wild
This hardy little character has made itself at home across Alaska, Nova Scotia, Quebec, Labrador, and Newfoundland. It’s clearly not afraid of a little cold weather – in fact, it seems to prefer it! If you’re gardening in these northern regions, you might already have this native treasure growing wild nearby.
Size and Growth Habits
Don’t expect this dogwood to tower over your garden beds. Cornus ×intermedia is what botanists call a low-growing shrub, typically staying under 1.5 feet tall and never exceeding 3 feet at maturity. It’s more of a ground-hugger than a sky-scraper, making it quite different from the tree-form dogwoods many gardeners know and love.
As a perennial, it’ll come back year after year, slowly establishing itself in your landscape with the patience that only northern plants seem to possess.
The Honest Truth About Growing This Plant
Here’s where things get a bit tricky – and we’re going to be completely honest with you. While Cornus ×intermedia is undoubtedly a fascinating native plant, detailed growing information specific to this hybrid is surprisingly scarce. This isn’t necessarily a bad thing; it just means this particular dogwood hasn’t made it onto the radar of most nurseries and garden centers.
What we do know is that it’s adapted to some pretty harsh northern climates, so if you’re gardening in its native range, it’s likely quite hardy and low-maintenance once established.
Should You Plant It?
The challenge with Cornus ×intermedia isn’t whether you should plant it, but whether you can find it! This hybrid isn’t commonly available in the nursery trade, which means sourcing it could be quite the adventure.
If you’re passionate about native plants and happen to live in its native range, this could be an exciting addition to a native plant collection or naturalistic landscape. However, for most gardeners looking for reliable dogwood options, you might want to consider other native Cornus species that are better documented and more readily available.
Alternative Native Dogwoods to Consider
If the idea of a native dogwood appeals to you but Cornus ×intermedia proves elusive, consider these alternatives:
- Cornus canadensis (Bunchberry) – another low-growing northern native
- Cornus sericea (Red-osier Dogwood) – excellent for wet areas
- Cornus alternifolia (Pagoda Dogwood) – beautiful layered branching
The Bottom Line
Cornus ×intermedia represents one of those fascinating plants that reminds us how much we still have to learn about our native flora. While it may not be the easiest plant to source or grow, it’s a testament to the incredible diversity of species that call North America home.
If you’re lucky enough to encounter this hybrid in the wild, take a moment to appreciate this quiet achiever of the northern landscape. And if you’re determined to add it to your garden, be prepared for a bit of detective work – both in finding the plant and in figuring out exactly how to keep it happy!
