A bed built around coral bells 'Plum Pudding'
The planner designed this bed around coral bells 'Plum Pudding' when this page was made: a 12 × 6 ft (3.7 × 1.8 m) English border in zone 6, part sun. It chose the other plants from the 708 that suit those conditions, and says below why coral bells 'Plum Pudding' stands where it does.
The plants
- 1 Coral bells 'Plum Pudding' × 5, purple leaves
- 2 Striped bloody cranesbill × 11, pink
- 3 Blue wood aster × 5, lavender
- 4 Garden phlox 'David' × 3, white
- 5 Dwarf English boxwood × 1, dark green leaves
- 6 Creeping Jacob's ladder × 8, blue
- 7 Hyacinth 'Delft Blue' × 3, blue
- 8 Daffodil 'February Gold' × 3, yellow
Why this plant
- The only bold leaves here. The rest are fine and medium. A change of leaf keeps plants distinct when nothing is in flower.
- Grown for leaf, not flower. So is dwarf English boxwood. Leaf lasts all season, where a flower lasts a few weeks.
Why here
- On the front edge. At 10 in it frames the bed without hiding it, and it is in leaf all season. It finishes 51% of the edge.
- 5 plants in one run. An unbroken run of one kind gives the edge a clean line.
- Bold leaf against fine. Striped bloody cranesbill is beside it: the strongest contrast of leaf there is.
Why now
- Here for its leaves, into winter. They cover the 8 weeks between early March and late November when nothing on the plan is in flower.
Planned as an English border: 6 of the 7 groups (86%) are drifts, longer along the bed than they are deep. Blue wood aster and garden phlox 'David' anchor the back corners of the bed: the tallest plants on the plan stand there. The bold leaves of coral bells 'Plum Pudding' are set against the fine leaves of striped bloody cranesbill, the kind of contrast that keeps a bed from blurring.
The planner's own design check: 15 Excellent, 2 Good. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

Where coral bells 'Plum Pudding' goes in a border
At 10 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: drift. Planted in a small group of three or five, and repeated further along in the other number.
One of the most reliable purple heucheras, and one that keeps a neat shape for years. The silver overlay catches low light, so it is never a dull, dead purple.
