Crataegus chlorosarca: A Mysterious Member of the Hawthorn Family
If you’ve stumbled across the name Crataegus chlorosarca in your plant research, you’re not alone in wondering about this elusive species. While the name suggests it belongs to the beloved hawthorn family (Crataegus), finding reliable information about this particular plant can be quite the botanical treasure hunt.





What We Know (And Don’t Know)
Crataegus chlorosarca appears to be either an extremely rare species, a regional variant with limited documentation, or possibly a name that has fallen out of current taxonomic use. The Crataegus genus includes hundreds of species of hawthorns found throughout temperate regions, but this particular species name doesn’t appear in major botanical databases or horticultural references.
The Challenge of Plant Identification
This situation highlights an important reality in gardening and botany—not every plant name you encounter will have readily available information. Sometimes plants are:
- Extremely rare or localized species
- Historical names that have been reclassified
- Regional common names that got mixed up with scientific names
- Potential misidentifications or typos
What About Hawthorns in General?
While we can’t provide specific growing advice for Crataegus chlorosarca, the hawthorn family in general offers wonderful options for native plant gardens. Most hawthorns are:
- Hardy, adaptable trees or shrubs
- Excellent for wildlife, providing berries for birds
- Beautiful spring bloomers with clusters of white or pink flowers
- Valuable for pollinators during their flowering season
A Word of Caution
If you’re considering planting any plant with uncertain identification, it’s wise to:
- Verify the plant’s identity with local botanists or extension services
- Research whether it might be invasive in your area
- Consider well-documented native alternatives instead
Better Safe Than Sorry
Rather than taking a chance on a plant with uncertain status, consider these well-documented native hawthorn alternatives that might be suitable for your area:
- Consult with your local native plant society
- Visit nearby botanical gardens for inspiration
- Work with reputable native plant nurseries
- Contact your county extension office for regional recommendations
Remember, successful native gardening is built on reliable information and appropriate plant selection. When in doubt, it’s always better to choose plants with well-documented growing requirements and known benefits to local ecosystems.
