Above are a few pics of this plant i have been growing for a few weeks in my back yard and i cant figure out what it is. Got a stalky, almost celery colored trunk about 5-12 inches wide in some places. Very sharp sides and points on the leaves that can cut straight through jeans. Its about 3 Feet tall right now, but appears to be growing at an alarming rate. Any suggestions on what it might be? PS... I live in North Texas so you know the climate.
