Carex laxiculmis Bunny Blue

Carex laxiculmis 'Bunny Blue' is a vine-plant that was discovered in the United States and is distinguished by a prostrate clump of fairly wide, evergreen leaves with a silvery-blue colour. It thrives in humid, partially shaded areas but also withstands sunlight and temporary droughts. With minimal suckering and a compact habit, it is suitable for moist rockeries, containers, and undergrowth borders. From June to July, discreet bronze spikelets appear. Hardy down to -15 °C (5°F)

The 'Bunny Blue' vine-plant, also known as Carex laxiculmis 'Hobb', is a hybrid of C. laxiculmis. This evergreen perennial is a rhizomatous plant of the Cyperaceae family, native to damp woods in eastern North America. In the wild, this species prefers cool, damp, partially shaded to shaded areas. It tolerates freezing temperatures (down to -15°C (5°F)) and adapts to any type of soil. The rarely spreading stump forms a low and stocky clump measuring 30cm (12in) in all directions. Insignificant flowering occurs in midsummer. This evergreen maintains its beautiful 1.2cm (1in) wide foliage throughout winter. Its colours will be more intense if exposed to full sunlight, which it cannot tolerate if planted in cool, rich soil.

Carex laxiculmis 'Bunny Blue' is a very bright border or rockery plant, bringing light and attracting attention to the least exposed corners of the garden. It will be perfectly at home near a small pond or stream, as long as the soil remains moist without being constantly waterlogged. It can also be planted in groups of 5 to 10 individuals at the edge of cool undergrowth or in the design of a green wall. Where it thrives, this vine-plant will form unique and highly decorative ground cover. It can be associated with other ground cover plants that enjoy similar conditions, such as small ferns (polypodium), hostas, other small carex, saxifrages, and ophiopogon.
