A bed built around sedge 'Everillo'
The planner designed this bed around sedge 'Everillo' when this page was made: a 12 × 6 ft (3.7 × 1.8 m) naturalistic planting in zone 6, part shade. It chose the other plants from the 513 that suit those conditions, and says below why sedge 'Everillo' stands where it does.
The plants
- 1 Sedge 'Everillo' × 4, chartreuse leaves
- 2 Green-and-gold × 11, yellow
- 3 Leadwort × 8, blue
- 4 Japanese meadowsweet × 3, pink
- 5 White turtlehead × 5, white
- 6 Bleeding heart 'Gold Heart' × 1, pink
- 7 Snowdrop × 12, white
- 8 Striped squill × 5, blue
Why this plant
- The only plant grown for its leaves. Leaf lasts all season, where a flower lasts a few weeks.
- The bed's only structure. Shrubs and grasses keep their shape when the perennials die down, and it is the only one here.
- Part of the matrix. The low fabric of grasses and groundcovers that the taller plants come up through.
Why here
- In the middle. At 14 in it is the step between leadwort (10 in) in front and white turtlehead (3 ft) behind: each is seen over the one before.
- 4 plants in one group. Massed, one kind reads as a single shape. Scattered, it would look spotty.
- Fine leaf against bold. Japanese meadowsweet is beside it: the strongest contrast of leaf there is.
Why now
- Here for its leaves, all year. They cover the 10 weeks between early March and late November when nothing on the plan is in flower.
- The only leaves in winter. From November to March it is what there is to look at.
Planned as a naturalistic planting: low grasses and groundcovers, the matrix, make up 49% of the planted ground. For contrast, the bold leaves of Japanese meadowsweet sit beside the fine leaves of sedge 'Everillo'. The back corners are held by white turtlehead and Japanese meadowsweet, the tallest plants on the plan.
The planner's own design check: 11 Excellent, 6 Good. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

Where sedge 'Everillo' goes in a border
At 14 in it belongs at the front of a bed. In the planner's ten height classes it is short (12 to 18 in).
Its job: edging. A low, neat plant used in short runs of three or five along the front to finish the edge (or, in a formal bed, in one even row).
Solid gold in shade, all year round. It is at its brightest against dark foliage: black mondo grass or the coppery new fronds of autumn fern.

What to plant with sedge 'Everillo'
Plants recorded as good partners for it, and what each pairing does:
- Hosta 'Halcyon': bold leaves against its fine ones; happy in the same moist soil.
- Black mondo grass: low enough (8 in) to stand in front of it.
- Autumn fern 'Brilliance': happy in the same moist soil.

Questions about sedge 'Everillo'
Does sedge 'Everillo' need sun or shade?
Sedge 'Everillo' grows in part sun (4 to 6 hours of sun, including some afternoon sun), part shade (2 to 4 hours of sun, mostly in the morning) and shade (less than 2 hours of direct sun, or bright dappled light).
It wants soil that stays evenly moist, of average fertility, and a good soak in dry spells. It copes with soil that stays wet.
What zones does sedge 'Everillo' grow in?
USDA zones 5 to 9. It is hardy to zone 5, which means it survives winter nights down to about −10 °F (−23 °C).
Gardening in Canada? Use the USDA zone for your town: Canada's own zone map uses different numbers.
How far apart should sedge 'Everillo' be planted?
16 in (40 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 20 in (50 cm), so a group knits into one patch.
It grows 14 in (35 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.
How many sedge 'Everillo' plants do I need?
At 16 in apart, set out in staggered rows:
- 7 to fill 10 square feet (about 1 m²)
- 8 for a single row 10 ft (3 m) long
- 21 to fill a 4 × 8 ft bed on its own
In a mixed border, plant it as runs of three or five along the front (or one even row, in a formal bed).
In the bed above, the planner used four in one group.
Is sedge 'Everillo' poisonous to dogs and cats?
No toxicity is recorded for dogs, cats, horses or people, according to NC State Extension.
"Not toxic" is not "edible": a pet that eats a lot of any plant can be sick.
Do deer eat sedge 'Everillo'?
Mostly not. NC State lists it as resistant to deer. No plant is proof against a hungry deer in a hard winter, but this one is low on the menu.
What does sedge 'Everillo' look like in winter?
Sedge 'Everillo' keeps its chartreuse leaves all winter, so it is one of the plants that hold a bed together from November to March, when the perennials have gone.
Is sedge 'Everillo' good for bees and butterflies?
Sedge 'Everillo' is visited by songbirds.
