| Special Attributes and Considerations |
The Black Walnut tree has a special defence mechanism know as Allelopathy. The tree's roots exude a natural herbicide known as juglone. The toxicity of juglones to other plants is still up for debate, but potatoes, tomatoes, apples and lilacs may be stunted if grown within close proximately to a Black Walnut tree. Rest assured, turf grass and Black Walnut trees get along just fine. |
| Folk Lore |
Medicine Hat has 3 Black Nuts trees with Heritage Tree status. These magnificent trees where planted by Mr. Earl Basset and they can be viewed at 114# Third St. NE. Over the years many seedlings have been germinated from the fallen nuts of these original Basset Black Walnut Trees. We even have some seedling of the same linage growing at our farm. |
