Purple Flame Grass flowers in late summer to fall in shades of silver, and performs best in full sun with low watering once established. This grass matures to roughly 4-7 feet tall and 3-5 feet wide. It is ideal for adding movement, texture, and winter structure to a border, offering movement, texture, and winter interest.
