Maybe it would sort of build up the gas circle. In that first turn after planting it gains 1 range, 2nd turn its range is 2, 3rd its range is 3, 4th is range is 4....and so on.

So, like the bramble(and sorta bombshell) that placing it is a risk, and the investment is over time. Then again could be OP if you just plant at your base and 5 turns later....well yeah
