Growing Hawthorn (Crataegus atrovirens): A Rare Canadian Native Tree
If you’re looking to add a native tree to your British Columbia landscape, you might have come across Crataegus atrovirens, a lesser-known member of the hawthorn family. While this particular species doesn’t get much spotlight in gardening circles, it represents an interesting piece of Canada’s native flora that deserves consideration for the right garden setting.
What is Crataegus atrovirens?
Crataegus atrovirens is a perennial hawthorn tree native to Canada, specifically found in British Columbia. Like other hawthorns, it’s a woody plant that typically grows as a single-stemmed tree, reaching heights of 13 to 16 feet or more under ideal conditions. However, environmental factors can sometimes cause it to develop a multi-stemmed, shrub-like form that stays under 13 feet tall.
Native Range and Distribution
This hawthorn species calls British Columbia home, making it a true Canadian native. Its limited geographic distribution makes it a special addition for gardeners specifically in this region who are passionate about growing plants that naturally belong in their local ecosystem.
Should You Plant This Hawthorn?
Here’s where things get a bit tricky. While Crataegus atrovirens appears to be a legitimate native species, there’s surprisingly little detailed information available about this particular hawthorn. This could mean a few things:
- It’s a rare or uncommon species with limited cultivation history
- It may be difficult to source from nurseries
- Growing requirements and characteristics aren’t well-documented
If you’re set on adding a native hawthorn to your British Columbia garden, you might want to consider better-documented hawthorn species that are known to thrive in cultivation and have established care guidelines.
Garden Role and Landscape Design
Based on its tree-like growth habit, Crataegus atrovirens would likely work well as:
- A specimen tree in larger gardens
- Part of a native plant border or naturalized area
- A component in wildlife-friendly landscapes (assuming it shares characteristics with other hawthorns)
Growing Conditions and Care
Unfortunately, specific growing requirements for Crataegus atrovirens aren’t well-documented. However, if it follows the pattern of other hawthorn species, it would likely prefer:
- Full sun to partial shade
- Well-draining soil
- Moderate water requirements once established
- Cold hardiness suitable for British Columbia’s climate zones
The Bottom Line
While Crataegus atrovirens has the appeal of being a native British Columbia species, the lack of readily available information makes it a challenging choice for most gardeners. If you’re determined to grow a native hawthorn, consider researching other well-documented Crataegus species native to your area, or consult with local native plant societies and botanical experts who might have more specific knowledge about this particular species.
Sometimes the most rewarding native plants are the ones that require a bit of detective work – just make sure you’re prepared for the adventure!
