This is growing wild beside the North end of the Bird to Gird bike trail.
Much larger than our dandelions.
Plant is 2-3' tall. Seed puff is approx 3" diameter.
I saved some seeds.
No leaves at base which is reddish.
Leaves wrap around stem like a grass leaf does and are alternate.
I dont know what it is. Have never seen it before and suspect it is not a native species.
Square stalk, no scent, found on slow moving waters edge.
