Uncinia rubra (also called Red hook sedge)
Low-growing, evergreen grass with rich red-brown leaves, originating in New Zealand. Goes well in containers, mixed beds and grass borders and contrasts well with silver-leaved plants.
So far, I have not seen sparrows taking the foliage for nesting material. Fingers crossed.
All year round.
Habit - clump-forming with arching foliage. H&S: 30-35cm.
Leaves - arching, leathery, rich red-brown.
Flowers - does not flower reliably, but may produce stems of small dark brown flowers in summer.
Full sun to partial shade.
Humus-rich, moisture-retentive but well drained. Unfussy as to acidity/alkalinity.
May need protection in very cold weather.
Lift and divide congested clumps every five years or so. Comb out old leaves using a hand fork or gloved hands.
By division from late spring to mid-summer or by fresh seed.
