I would really love to know, how fast does orange rocket barberry grow? π
As far as I know, when it's fully grown, it can grow to be about 4-5 feet tall and about 2-3 feet wide.
I think you'll see around 3β4 feet of growth in 2β3 years.
Sorry, I have no idea.
This shrub plant is absolutely stunning, isn't it? It's amazing how quickly it grows β around 2 feet or more per year!
