A bed built around striped bloody cranesbill

The planner designed this bed around striped bloody cranesbill when this page was made: a 12 × 6 ft (3.7 × 1.8 m) English border in zone 6, full sun. It chose the other plants from the 966 that suit those conditions, and says below why striped bloody cranesbill stands where it does.

A 12 × 6 ft (3.7 × 1.8 m) bed at eye level in mid July: Striped bloody cranesbill, October daphne, False sunflower 'Summer Sun', Switchgrass 'Shenandoah', Deutzia 'Chardonnay Pearls', Wild quinine, Schubert's allium, Spring starflower.

Why this plant

  • The only open bowls. The others are dense clusters, daisies, bells and others. Shape reads at a distance, where colours blur.

Why here

  • On the front edge. At 6 in it frames the bed without hiding it, and it is in leaf all season. It finishes 42% of the edge.
  • 5 plants in one run. An unbroken run of one kind gives the edge a clean line.

Why now

  • In flower for 14 weeks. From late May to late August.
  • Part of the bed's peak. With deutzia 'Chardonnay Pearls' and Schubert's allium in late May: 3 kinds at once. No week has more.

Planned as an English border: 5 of the 5 groups (100%) are drifts, longer along the bed than they are deep. The flowering is at its height in late May, with 3 kinds out together. Pink is the colour seen most, on 3 of the 7 kinds grown for their flowers.

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 striped bloody cranesbill goes in a border

At 6 in it belongs at the front of a bed. In the planner's ten height classes it is ground-hugging (up to 6 in).

Its job: carpet. A groundcover planted in threes and fives to cover the soil: along the front, and just behind it.

The neatest and longest-flowering hardy geranium for edging. It comes from Walney Island in Lancashire, where it grows on sand dunes, so it stands drought and wind.

  • Edging in sun
  • Dry banks and wall tops
  • A long flowering season at the front

What to plant with striped bloody cranesbill

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

  • Lamb's ear: its silver leaves are a setting for the flowers, before and after; bold leaves against its fine ones; spires rising out of its mound.
  • Catmint 'Walker's Low': in flower together for 14 weeks, from late May; spires rising out of its mound; tall enough (24 in) to stand behind it.
  • Blue fescue: its blue-green leaves are a setting for the flowers, before and after; tall enough (10 in) to stand behind it.

Questions about striped bloody cranesbill

Does striped bloody cranesbill need sun or shade?

Striped bloody cranesbill grows in full sun (6 or more hours of direct sun a day) and part sun (4 to 6 hours of sun, including some afternoon sun).

It wants ordinary well-drained soil, of average fertility, and little watering once settled.

What zones does striped bloody cranesbill grow in?

USDA zones 3 to 8. It is hardy to zone 3, which means it survives winter nights down to about −30 °F (−34 °C).

Above zone 8 it struggles: the zones measure winter cold, but a plant's top zone usually means the summers are too hot or the winters too mild for it to rest.

When does striped bloody cranesbill flower in my zone?

In zone 5 it flowers late May to late August. As a spring flower it moves about a week for every zone: earlier where it is warmer, later where it is colder.

Roughly when striped bloody cranesbill is in flower
Zone 3Early June to late August
Zone 4Late May to late August
Zone 5Late May to late August
Zone 6Mid May to late August
Zone 7Early May to mid August
Zone 8Early May to mid August

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 striped bloody cranesbill 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 18 in (45 cm), so a group knits into one patch.

It grows 6 in (15 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.

How many striped bloody cranesbill 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 threes and fives, along the front and just behind it.

In the bed above, the planner used five in one group.

Is striped bloody cranesbill 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.

Is there a native plant like striped bloody cranesbill?

Striped bloody cranesbill comes from Europe to Caucasus. These North American natives come closest to doing its job:

  • Creeping phlox: the same job in a bed, the same size and the same colour; flowers mid April to mid May.
  • Woodland strawberry: the same job in a bed and the same flowering time; 4 in narrower, white, not pink.

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

Do deer eat striped bloody cranesbill?

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 striped bloody cranesbill?

Striped bloody cranesbill is over by late August. These start as it finishes and carry the same spot on, so it never goes flat:

What does striped bloody cranesbill look like in winter?

Striped bloody cranesbill dies down to the ground and there is nothing to see until spring. The old stems can be cut in autumn, or left until spring as shelter for overwintering insects.

Is striped bloody cranesbill good for bees and butterflies?

Striped bloody cranesbill is visited by pollinators, specialist bees and butterflies.
