Umbel Like Sedge

Carex tonsa var. rugosperma

Also Known As - Parachute Sedge
Umbel Like Sedge (Carex tonsa var. rugosperma) is a perennial wetland sedge native to North America. The separate plants commonly reach up 30 cm tall and form dense clumps of upright grass-like stems. The unusual oval-shaped inflorescences are umbel-like, with yellowish brown spikelets in the center. The short, triangular leaves are green to grey-green. This species prefers moist, acidic soils and is a great choice for rainy, boggy areas near water or streams. Carex tonsa var. rugosperma makes a great addition to shady perennial borders and is deer and rabbits resistant.

watering

Umbel Like Sedge (Carex tonsa var. rugosperma) should be watered regularly and deeply. During the growing season, the plant will require weekly watering. One to 2 inches of water should be supplied per week and the soil should be allowed to dry out between waterings. During the cooler months, it will require less watering and should typically be watered every 2 weeks. In both cases, it is important to water deeply to ensure that the roots of the plant have access to ample moisture.

sunlight

Umbel Like Sedge (Carex tonsa var. rugosperma) prefers full sun to partial shade and in dry to moist soils. This plant species typically grows taller in moist soils and prefers sunny areas of more than 6 hours of direct sunlight per day. In more shaded areas, Umbel Like Sedge can grow but may reach a smaller average height. During the summer months it can easily tolerate the heat if it's provided with enough moisture.

pruning

Umbel Like Sedge should be pruned after blooming but before the formation of the seeds. Pruning can be done with scissors or clippers. Pruning should only remove the flowering stems, leaving the green, vegetative growth in place. This should be done in the early summer to encourage a new flush of growth in August. Prune all stems back to 2-4 inches above ground level to get a more dense, compact shape. Prune any dead or damaged foliage. Over-pruning should generally be avoided, as the plant may not flower again that season if it’s cut back too far.
