| Author's Notes | I started growing this plant (a Campsis cultivar called Atomic Red) in the summer of 2014. By the end of 2015, it had one stem over 8 feet tall and another dozen or so shorter branches. It was already starting to sucker from the base. When the stems get long, I just wind them a turn or two onto the large trellis (12 feet tall by 12 feet wide and still growing). |
