About

Carex siderosticta 'Shima-nishiki' is a compact, deciduous perennial that typically grows to a height of 20-30 cm. It develops dense clumps of wide, linear leaves that range from pale to bright green, featuring creamy-yellow edges and subtle striping. In late spring, slender flower spikes, reaching up to 30 cm in length, emerge from the foliage, displaying pale brown blooms. This plant spreads gradually, making it suitable for various garden settings.
