Pistil stitch is an extended or elongated French knot….
Make one, two or three wraps around the needle as you would with a French knot,
but instead of inserting the needle close to where the thread emerges,
insert it further away, depending on the size of the stalk that you require.
This stitch is ideal for long grass, or for creating a knobbly texture where ordinary French knots
would result in too heavy a texture.
