CAREX NIGRA ‘ON-LINE’
This small, clump-forming sedge has variegated grey-green leaves with a narrow golden edge that make it stand out when used between other plants. Its leaves look beautiful right up until winter when the gold-coloured hue becomes more intense. Between April and June it blooms with dark-brown spikes. Perfect for pots, it also a great groundcover for larger surfaces, without being too invasive. Best of all, this Carex is very resistant to frost and will grow in wet soil.
