The chemical substances within the berries would quickly paralyze the fish, inflicting them to drift in direction of the water’s floor. Folks would then collect the surprised fish downstream.
Since that fantastic autumn day of my coralberry discovery, I’ve bought a cultivar of coralberry from Confirmed Winners– ‘Proud Berry.’ I’ve loved the massive, mild pink fruits in my landscaping and fresh-cut flower preparations!
