| Author's Notes | I just started growing this plant in the summer of 2014. By the end of 2015, it had one stem over 8 feet tall with another dozen or so shorted branches. Already starting to sucker from the base. When the stems get long, I wind them a turn or two onto the large trellis (8 feet tall by 12 feet wide), in the summer of 2018, only a few flowers. I am starting to wonder if this plant doe not like the site I planted it. It should be more robust by now. Now (2022), it has lived up to its name of being very aggressive. Suckers are showing up all around the plant. |
