Limestone Meadow Sedge

Year-round

Limestone Meadow Sedge is native to Tennessee and does well in Memphis yards with moist, clay or lime-rich soil and part shade to sun.

• Native to Tennessee statewide, per University of Tennessee Smart Yards and the Lady Bird Johnson Wildflower Center, so it is a solid pick for a Memphis native planting.
• Give it wet to medium moisture. It handles clay and calcareous (limestone-influenced) soil, which is common around Memphis, and tolerates a pH from slightly acid to alkaline.
• It takes full sun to full shade, so it fits under trees, along a shady foundation bed, or in a sunnier low spot that stays damp.
• Forms low, dense clumps one to two feet tall and spreads slowly by rhizomes and reseeding, so it fills in a bed without becoming aggressive.
• It is a cool season grower, most active in spring and fall, which lines up with Memphis's mild spring and fall and hot, humid summer.

Fall

Fall brings a second cool season growth spurt in Memphis, a good time to plant, divide, or just let the clump fill back in.

• As Memphis temperatures cool, this sedge picks growth back up, so fall is a strong window to plant new starts or divide an established clump.
• Keep soil evenly moist as it resumes growing. Fall rains are often enough, but check during any dry stretch.
• Leave the foliage standing through fall. There is no need to cut it back now, and the blue green to gray green blades still look tidy into the cooler months.
• Seed has usually finished by this point, so any self-sown seedlings nearby are easy to spot and thin if you want to keep the clump contained.

Winter

Winters in Memphis are mild enough that this sedge needs little care beyond a tidy-up if the clump looks rough.

• This species is winter hardy well north of Memphis, so a typical Memphis winter (USDA zone 7b to 8a) is easy for it to handle.
• Foliage may fade or flop in cold snaps. If it looks worn, cut the clump back to a few inches any time in late winter before spring growth starts.
• No winter watering is usually needed since the plant is dormant or semi-dormant and Memphis winters bring regular rain, but check soil if there is an extended dry, mild spell.
• No mulch or wrapping is needed for cold protection here. This is a hardy wet meadow native, not a tender ornamental.

A late winter cutback of tattered foliage keeps the bed looking neat before spring growth starts.

Spring

Spring is peak growth for this sedge in Memphis, with fresh green blades and flowering by May.

• This is a cool season sedge, so it puts on most of its new growth now while Memphis soil is still cool and moist.
• Keep the root zone damp. A wet spring is usually enough, but water during any dry stretch since this plant is a wet meadow species at heart.
• Flower and seed heads appear from May into June, small and grassy rather than showy, so no deadheading is needed for bloom.
• If old foliage looks tattered from winter, a light trim to a few inches now tidies the clump before new blades take over.

A quick spring trim of old foliage keeps the clump looking neat from the street without cutting into the plant's bloom.

Summer

Memphis summer heat and humidity slow this cool season sedge down, so the main job is keeping it from drying out.

• Growth naturally slows in the heat of a Memphis summer since this is a cool season plant. That is normal and not a sign of a problem.
• Because it is a wet to medium moisture species, watch for dry spells and water deeply rather than letting the soil go dry, especially in a sunnier spot.
• In full sun locations, expect more moisture stress than in part shade or shade, so a partly shaded bed is more forgiving through Memphis summers.
• No fertilizer is needed. This sedge is adapted to average to moist native soil, not rich feeding.
