Across the alley from (and a bit cattycorner to) our lot at 1521 Ninth Street in the Fairview Neighborhood sat this massive wild rhubarb bush. It was directly across from the abandoned tiny garage at the bottom of the Brooks lot. This growth was quite impressive – both in physical scale and in the quantity of burrs it produced.
A bur (also spelled burr) is a seed or dry fruit or infructescence in which the seeds bear hooks or teeth which attach themselves to the fur of passing animals or the clothing of people. The hooks or teeth can be irritants and very hard to remove from clothing, such as wool or cotton. The bur of burdock was the inspiration for Velcro. – Wikipedia
