Carex tomentosa: complete guide

Overview

Carex tomentosa, better known as Downy-fruited sedge or Felt sedge, is an elegant sedge from Europe. This plant occurs naturally from the United Kingdom to Turkey and further east to Mongolia. The plant is named after its characteristic velvet-like, hairy fruits (tomentose means hairy in Latin).

Appearance and Bloom

Carex tomentosa grows as a dense, low-growing plant, usually not taller than 40 centimetres. It forms attractive, compact tufts with fine, green leaves. The most striking feature is the fruits which are densely hairy, giving the plant its characteristic velvet-like appearance.

The flower spikes appear in May and June and are yellow to green in colour. After flowering, the hairy fruits develop which are highly decorative and remain attractive for a long time.

Ideal Location

The Downy-fruited sedge prefers partial shade to full sun. It grows optimally in locations with less intense light, making it suitable for mixed borders and under large trees. The plant can also grow in full sun on moist soils. It is very suitable for woodland edges, heathland areas and mixed plantings.

Soil

Carex tomentosa is not fussy about soil type. It grows well on acidic to neutral soils. Humus-rich, moderately moist soils are ideal. The plant also tolerates drier situations reasonably well once established. It can thrive on various soils from clay to sand.

Watering

Once established, this sedge is very low-maintenance. Watering during the first growing season is important, after that it can tolerate considerable drought. Ensure the planting hole is well moistened at planting time.

Pruning

Minimal pruning is needed. Remove dead leaves in early spring (March) to keep the plant tidy. The plant requires no special pruning otherwise.

Maintenance Calendar

February to March: Remove dead leaves. April to May: Growing period, water regularly. June to August: Flowering and fruiting, highly decorative. September to October: Plant moderates activity. November to December: Rest period.

Winter Hardiness

Carex tomentosa is fully hardy throughout Europe, from Northern Europe to Southern Europe. Temperatures down to -20 degrees Celsius are no problem.

Companion Plants

Combine with other ground covers such as ivy, saxifrage, or cushion plants. With ferns it forms beautiful shade plantings. In full sun combine it well with low-growing flowering plants.
