Keyflower: An Intriguing Orchid for Specialized Gardens
Meet the keyflower (Dactylorhiza majalis praetermissa var. praetermissa), a perennial orchid that’s quietly made itself at home in parts of eastern Canada. While this fascinating flowering plant might not be on every gardener’s radar, it offers some unique characteristics that make it worth considering for the right garden setting.
What Is Keyflower?
Keyflower is a herbaceous perennial that falls into the forb category—meaning it’s a non-woody flowering plant that dies back to the ground each winter and returns the following spring. As an orchid, it brings that special mystique that makes these plants so captivating to gardeners and nature lovers alike.
This particular variety is what botanists call a non-native naturalized species in Canada. It was originally introduced but has proven quite capable of reproducing and persisting in the wild without any human intervention—a testament to its adaptability.
Where Does Keyflower Grow?
Currently, keyflower has established itself in Newfoundland, where it’s found growing in suitable habitats. Its presence in this eastern Canadian province suggests it’s well-adapted to cooler, maritime climates.
Should You Grow Keyflower in Your Garden?
This is where things get interesting. As a non-native species, keyflower sits in that middle ground that many gardeners find themselves navigating. It’s not listed as invasive or problematic, but it’s also not contributing to local native ecosystems in the same way indigenous plants do.
Here are some considerations:
- For orchid enthusiasts: If you’re passionate about orchids and have experience growing these specialized plants, keyflower could be an intriguing addition to your collection
- For native plant gardeners: You might want to explore native orchid alternatives that provide similar beauty while supporting local wildlife
- For beginners: Orchids in general require specific growing conditions and care, so this might not be the best starting point for new gardeners
Growing Conditions and Care
Unfortunately, specific growing requirements for this particular variety are not well-documented in readily available sources. However, as a member of the orchid family, keyflower likely shares some common needs with its relatives:
- Well-draining soil that doesn’t stay waterlogged
- Consistent moisture without being soggy
- Protection from extreme weather conditions
- Possible symbiotic relationship with specific soil fungi (mycorrhizae)
Given its naturalization in Newfoundland, it’s probably adapted to cooler growing zones, but specific hardiness information isn’t readily available.
Native Alternatives to Consider
If you’re drawn to the idea of growing native orchids, Canada has several beautiful indigenous species that might better serve your garden and local ecosystem:
- Pink lady’s slipper (Cypripedium acaule)
- Showy orchis (Galearis spectabilis)
- Large round-leaved orchid (Platanthera orbiculata)
These native alternatives will provide similar orchid appeal while supporting local pollinators and fitting naturally into regional ecosystems.
The Bottom Line
Keyflower represents an interesting case study in plant naturalization. While it’s not causing ecological harm, it’s also not providing the same benefits as native species would. If you’re specifically interested in this orchid and have experience with orchid cultivation, it could make an interesting addition to a specialized garden. However, for most gardeners, exploring native orchid options might be a more rewarding path that benefits both your garden and local wildlife.
Remember, successful orchid growing often requires patience, specific conditions, and sometimes a bit of trial and error. Whether you choose keyflower or a native alternative, be prepared for the unique joys and challenges that come with growing these remarkable plants.
