A bed built around Virginia sweetspire 'Henry's Garnet'
The planner designed this bed around Virginia sweetspire 'Henry's Garnet' when this page was made: a 16 × 8 ft (4.9 × 2.4 m) English border in zone 6, part sun. It chose the other plants from the 708 that suit those conditions, and says below why Virginia sweetspire 'Henry's Garnet' stands where it does.
The plants
- 1 Virginia sweetspire 'Henry's Garnet' × 1, white
- 2 Mossy saxifrage × 30, pink
- 3 Leadwort × 22, blue
- 4 Feather reed grass 'Avalanche' × 4, tan
- 5 Foxglove beardtongue × 5, white
- 6 Japanese forest grass 'Beni-kaze' × 4, green leaves
- 7 Camassia × 3, blue
- 8 Easter lily × 3, white
- 9 Checkered lily × 12, purple
Why this plant
- Part of the bed's structure. Shrubs and grasses keep their shape when the perennials die down. So do feather reed grass 'Avalanche' and Japanese forest grass 'Beni-kaze'.
Why here
- Anchors a back corner. At 4 ft it is one of the taller plants here, and the tallest close the ends of the bed, where they stand in front of nothing.
- A step in the back row. Next to feather reed grass 'Avalanche' (5 ft): no two neighbours there are the same height, so the back steps up and down like a skyline.
- One plant, alone. A shrub is seen as an object, and needs clear ground around it.
Why now
- In flower for five weeks. From early June to early July.
- Part of the bed's peak. With feather reed grass 'Avalanche', foxglove beardtongue and Easter lily in late June: 4 kinds at once. No week has more.
Planned as an English border: 7 of the 7 groups (100%) are drifts, longer along the bed than they are deep. Neither end outweighs the other: the visual weight is split 48 to 52, left to right. The bed is tied together by its repeats: four kinds come round again along it, among them mossy saxifrage and leadwort.
The planner's own design check: 13 Excellent, 4 Good.

Where Virginia sweetspire 'Henry's Garnet' goes in a border
At 4 ft it belongs at the back of a bed. In the planner's ten height classes it is moderately tall (3 to 4 ft).
Its job: anchor. A shrub that gives the bed permanent structure. Planted singly, as soon as the front edge is laid; everything else is arranged around it.
The best form of a first-rate native shrub. Its autumn colour is as good in shade as in sun, which is rare. It spreads by suckers, which suits a bank or a damp hollow.

How far apart should Virginia sweetspire 'Henry's Garnet' be planted?
4 ft (120 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 5 ft (150 cm), so a group knits into one patch.
