A bed built around lilyturf

The planner designed this bed around lilyturf when this page was made: a 12 × 6 ft (3.7 × 1.8 m) cottage garden in zone 6, part sun. It chose the other plants from the 708 that suit those conditions, and says below why lilyturf stands where it does.

A 12 × 6 ft (3.7 × 1.8 m) bed at eye level in late August: Lilyturf, Moor grass 'Greenlee', Bloody cranesbill 'Max Frei', Swamp milkweed 'Ice Ballet', Bellflower 'Kent Belle', Inkberry 'Gem Box', Grecian windflower, Autumn crocus.

Why this plant

  • Nothing here is unique to it. Its leaf, flower shape and colour are all on the plan already. Its case rests on where it stands and when it performs.

Why here

  • In the middle. At 16 in it is the step between moor grass 'Greenlee' (12 in) in front and inkberry 'Gem Box' (2½ ft) behind: each is seen over the one before.
  • A step in the back row. Next to swamp milkweed 'Ice Ballet' (3½ ft) and inkberry 'Gem Box' (2½ ft): no two neighbours there are the same height, so the back steps up and down like a skyline.
  • 12 plants in 2 groups (9 and 3). Seen again further along, the same plant ties the bed together.

Why now

  • In flower for six weeks. From early August to mid September.
  • Fills a gap. For three of those weeks nothing else on the plan is in flower.
  • One of two evergreens. They are what the bed has to show from November to March.

Planned as a cottage garden: 21 of the 30 plants (70%), bulbs aside, stand alone or in groups of no more than five, small enough for the kinds to mingle. Grecian windflower comes up between the other plants for colour early in the year. Lilyturf is planted in two places along the bed, which gives it rhythm.

The planner's own design check: 12 Excellent, 5 Good. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

Where lilyturf goes in a border

At 16 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).

The most forgiving edging plant for warm climates: it grows in sun, shade, drought and root competition. This species stays in clumps. Mow or shear the old leaves in late winter.

  • Evergreen edging in sun or shade
  • Under trees
  • Low-maintenance mass planting

What to plant with lilyturf

Plants recorded as good partners for it, and what each pairing does:

  • Hosta: its green leaves are a setting for the flowers, before and after; bold leaves against its medium ones; a low mound at the foot of its spires.
  • Lenten rose: flowers first, late March to early May, so the spot is never empty; bold leaves against its medium ones; a low mound at the foot of its spires.
  • Autumn fern: its dark green leaves are a setting for the flowers, before and after.

Questions about lilyturf

Does lilyturf need sun or shade?

Lilyturf grows in full sun (6 or more hours of direct sun a day), 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 is one of the few that also put up with deep shade.

It wants ordinary well-drained soil, of average fertility, and little watering once settled. Once settled in, it stands drought.

What zones does lilyturf grow in?

USDA zones 5 to 10. 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.

When does lilyturf flower in my zone?

In zone 5 it flowers early August to mid September. As a summer flower it moves about half a week for every zone: earlier where it is warmer.

Roughly when lilyturf is in flower
Zone 5Early August to mid September
Zone 6Early August to mid September
Zone 7Early August to mid September
Zone 8Early August to mid September
Zone 9Late July to mid September

Worked out from Hopkins' bioclimatic law: spring arrives about four days later for each degree of latitude north, and one zone is roughly two degrees. A warm spring or a cold one moves any garden two weeks either way.

How far apart should lilyturf be planted?

12 in (30 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 18 in (45 cm), so a group knits into one patch.

It grows 16 in (40 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.

How many lilyturf plants do I need?

At 12 in apart, set out in staggered rows:

  • 12 to fill 10 square feet (about 1 m²)
  • 11 for a single row 10 ft (3 m) long
  • 38 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 12 in two groups.

Is lilyturf poisonous to dogs and cats?

No toxicity is recorded for dogs, cats, horses or people, according to NC State Extension and the ASPCA.

"Not toxic" is not "edible": a pet that eats a lot of any plant can be sick.

Is there a native plant like lilyturf?

Lilyturf comes from China, Taiwan, and Japan. These North American natives come closest to doing its job:

  • Chives: the same job in a bed, the same size and the same colour; flowers mid May to mid June, fine leaves, not medium.
  • Coral bells 'Firefly': the same job in a bed; 6 in shorter, flowers late May to late July.

Matched the way the planner's Swap button matches plants: the same job in a bed, then size, then flowering time.

Do deer eat lilyturf?

Mostly not. NC State lists it as resistant to deer and rabbits. No plant is proof against a hungry deer in a hard winter, but this one is low on the menu.

What flowers after lilyturf?

Lilyturf is over by mid September. These start as it finishes and carry the same spot on, so it never goes flat:

  • Garden chrysanthemum: from mid September to late October, 24 in tall.
  • October daphne: from mid September to late October, 8 in tall, to stand in front of it and cover its fading stems.
  • Meadow saffron: from mid September to mid October, 6 in tall, to stand in front of it and cover its fading stems.

What does lilyturf look like in winter?

Lilyturf keeps its dark green leaves all winter, so it is one of the plants that hold a bed together from November to March, when the perennials have gone.
