Japanese Stiltgrass (Eulalia)
An annual grass with thin, pale green, lance-shaped leaves that are 3 inches long. The midvein of the leaf is off-center and has a distinct silvery stripe of reflective hairs. Flower spikes form at the slender stem tips in late summer. Each plant produces hundreds of small, yellow-to-red seeds that can remain viable for five years. Blooms September through October.
