Giant feather grass, also called giant needle grass or golden oats, is a tall, tufted bunchgrass native to Spain and Portugal. Growing 3-4 feet tall (to 6 feet with flower spikes), it produces narrow, gray-green leaves and ethereal, feathery seed heads that shimmer gold in light.
Giant feather grass is extremely drought-tolerant once established and thrives in full sun with well-drained, sandy or rocky soil. Hardy to zones 6-9, it is slow-growing and long-lived. The spectacular seed heads persist through fall and winter, providing extended ornamental interest. The plant is excellent for focal points in gardens.
