A bed built around cottage pinks 'Mrs Sinkins'

The planner designed this bed around cottage pinks 'Mrs Sinkins' 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 715 that suit those conditions and its dry soil, and says below why cottage pinks 'Mrs Sinkins' stands where it does.

Why this plant

  • The only open bowls. The others are dense clusters, spires, daisies and others. Shape reads at a distance, where colours blur.
  • The only white. White sits between stronger colours and calms them.

Why here

  • On the front edge. At 12 in it frames the bed without hiding it, and it is in leaf all season. It finishes 27% of the edge.
  • 5 plants in one run. An unbroken run of one kind gives the edge a clean line.
  • Fine leaf against bold. Silver sage is beside it: the strongest contrast of leaf there is.

Why now

  • In flower for five weeks. From early June to early July.
  • Part of the bed's peak. With wild lupine and ornamental onion 'Purple Sensation' in early June: 3 kinds at once. No week has more.
  • The only leaves in winter. From November to March it is what there is to look at.

Planned as an English border: 7 of the 8 groups (88%) are drifts, longer along the bed than they are deep. The bed is balanced: the left half carries 51% of the visual weight and the right half 49%. The bed is tied together by its repeats: two kinds come round again along it, leadwort and wild lupine.

The planner's own design check: 14 Excellent, 3 Good. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

Where cottage pinks 'Mrs Sinkins' goes in a border

At 12 in it belongs at the front of a bed. In the planner's ten height classes it is low (6 to 12 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).

Grown for scent and sentiment: the flowers are a mess and nobody minds. It flowers once, in June. Take cuttings every few years, as old plants go woody and bare.

Questions about cottage pinks 'Mrs Sinkins'

Does cottage pinks 'Mrs Sinkins' need sun or shade?

It wants dry, sharply drained soil, on the lean side, with no feeding, and little watering once settled.

USDA zones 4 to 8. It is hardy to zone 4, which means it survives winter nights down to about −20 °F (−29 °C).
