I didn’t plant it, but we got top soil from a garden centre last year and presume there was a seed there that’s settled in well! It’s about 4 ft tall now and popping seeds all over the place! 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 7 years ago This is caper spurge, not real capers, and not edible.
