Are you sure you are talking about the detonation velocity of hydroxy gas, and not hydrogen in air? They are quite different you know. Anything that puts out that much concussive energy can cause injury or death. Granted, hydroxy gas in a balloon or bag is not near as dangerous as a container full of hydroxy gas that can become shrapnel. A plant such as a bush would not be as affected by the shock wave as a person or animal would be, totally different anatomy. Shock waves can pass right through leaves and branches with little impact. We mammals are a bit more vulnerable to shock waves 
It is much better to err on the side of caution than to encourage someone to make a fatal mistake.
