Forbes’s Hawthorn: A Rare New England Native Worth Knowing

If you’re a native plant enthusiast with a passion for rare finds, Forbes’s hawthorn (Crataegus forbesiae) might just pique your interest. This lesser-known member of the hawthorn family is one of those botanical gems that makes you feel like you’ve discovered a secret—mainly because so few people have ever encountered one!

What Exactly Is Forbes’s Hawthorn?

Forbes’s hawthorn is a native perennial shrub that calls a very small corner of New England home. Like other hawthorns, it’s a multi-stemmed woody plant that typically stays under 13-16 feet tall, though it can occasionally stretch taller or develop a single trunk depending on growing conditions. You might also see it listed as Crataegus forbesae in some older references—that’s just a spelling variation of the same plant.

Where Can You Find It?

Here’s where things get interesting (and a bit exclusive): Forbes’s hawthorn has one of the most limited native ranges you’ll find among North American plants. It’s only documented in Connecticut and Massachusetts, making it a true New England specialty. This incredibly restricted distribution immediately raises some red flags for gardeners interested in growing it.

  • Species observed
  • No observations

Should You Plant Forbes’s Hawthorn?

The short answer is: probably not, and here’s why. The extremely limited range of this species suggests it may be quite rare in the wild, though we don’t have definitive data on its conservation status. When a plant is found in only two states, it’s often wise to leave it in its natural habitat rather than attempting to cultivate it in gardens.

Additionally, there’s remarkably little information available about this species’ specific growing requirements, appearance, or garden performance. This lack of horticultural knowledge makes it a risky choice for home gardeners.

Better Alternatives for Your Garden

If you’re drawn to the idea of growing a native hawthorn, consider these more widely available and better-documented alternatives:

  • Downy Hawthorn (Crataegus mexicana) – More widely distributed and better studied
  • Black Hawthorn (Crataegus douglasii) – Excellent for wildlife and well-adapted to cultivation
  • Cockspur Hawthorn (Crataegus crus-galli) – Striking fall color and reliable garden performance

Growing Conditions and Care

Based on its wetland status as Facultative Upland, Forbes’s hawthorn seems to prefer non-wetland conditions but can tolerate some moisture. Like most hawthorns, it would likely appreciate:

  • Full sun to partial shade
  • Well-draining soil
  • Moderate water needs
  • Cold tolerance suitable for its native New England range

However, without specific horticultural trials and documentation, these are educated guesses based on related species and its natural habitat.

The Bottom Line

Forbes’s hawthorn represents one of those fascinating botanical mysteries that remind us how much we still don’t know about our native flora. While it’s tempting to want to grow every native plant we discover, sometimes the most responsible approach is to appreciate these rarities in their natural settings and choose better-known native alternatives for our gardens.

If you’re passionate about supporting native New England plants, focus on well-documented species that you can grow successfully while contributing to local ecosystem health. Save the rare finds like Forbes’s hawthorn for botanical field trips and nature photography!

Crataegus forbesiae is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Crataegus forbesiae is also known as:

Crataegus forbesae , orth. var. | USDA symbol: CRFO8

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.

Wetland Status

The rule of seasoned gardeners and landscapers is to choose the "right plant for the right place" — matching plants to their ideal growing conditions, so they'll thrive with less care and fewer inputs. But the simplicity of this catchphrase conceals how tricky plant selection can be if you don't have the right information. While tags on nursery plants list watering requirements, there's more to the story.

Knowing a plant's wetland status can simplify the process by revealing the interaction between plants, water, and soil. You might be surprised to learn that popular landscape plants are wetland species! And what may be a wetland plant in one area, in another it might thrive in drier conditions. The table below gives insight into the preferred growing conditions of this plant throughout its geographical distribution.
