A bed built around sedum 'Dragon's Blood'
The planner designed this bed around sedum 'Dragon's Blood' 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 sedum 'Dragon's Blood' stands where it does.
The plants
- 1 Sedum 'Dragon's Blood' × 22, red
- 2 Sea thrift × 6, pink
- 3 Little bluestem 'The Blues' × 5, tan
- 4 False sunflower 'Summer Nights' × 3, yellow
- 5 Silver sage × 1, silver leaves
- 6 Sunset hyssop × 3, orange
- 7 Ornamental onion 'Purple Sensation' × 2, purple
- 8 Spring starflower × 12, blue
Why this plant
- The only dense clusters. The others are globes, spires and daisies. Shape reads at a distance, where colours blur.
- The only red.
Why here
- Under the taller plants. It runs back between them as living mulch: there its job is to cover the soil, not to be looked at.
- 22 plants in 6 groups (5, 5, 3, 3, 3 and 3). Seen again further along, the same plant ties the bed together.
Why now
- In flower for 7 weeks. From late June to early August.
- Part of the bed's peak. With little bluestem 'The Blues', false sunflower 'Summer Nights' and sunset hyssop in early August: 4 kinds at once. No week has more.
Planned as an English border: 5 of the 6 groups (83%) are drifts, longer along the bed than they are deep. Neither end outweighs the other: the visual weight is split 53 to 47, left to right. Sedum 'Dragon's Blood' is planted in six places along the bed, which gives it rhythm. Every line of the Design check comes out Good or better.
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 sedum 'Dragon's Blood' goes in a border
At 4 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.
A succulent mat for places too hot and dry for anything else. The burgundy tint of the leaves picks up reds and pinks elsewhere in the bed and contrasts with silver and blue foliage.
- Hot, dry front edges and rock gardens
- Green roofs and gravel
- Red-tinged foliage as a contrast to silver leaves
What to plant with sedum 'Dragon's Blood'

- Lamb's ear: its silver leaves are a setting for the flowers, before and after; bold leaves against its medium ones; spires rising out of its mound.

When does sedum 'Dragon's Blood' flower in my zone?
In zone 5 it flowers late June to early August. As a summer flower it moves about half a week for every zone: earlier where it is warmer.
| Zone 3 | Early July to mid August |
|---|---|
| Zone 4 | Early July to mid August |
| Zone 5 | Late June to early August |
| Zone 6 | Late June to early August |
| Zone 7 | Late June to early August |
| Zone 8 | Late June to early August |
| Zone 9 | Mid June to late July |
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 sedum 'Dragon's Blood' 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 4 in (10 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.
How many sedum 'Dragon's Blood' 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 threes and fives, along the front and just behind it.
In the bed above, the planner used 22 in six groups.
Is sedum 'Dragon's Blood' poisonous?
Yes: mild toxicity to people. May cause mild stomach upset if eaten.
Rated from NC State Extension. Where references disagree, the more cautious rating is used.
Do deer eat sedum 'Dragon's Blood'?
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 sedum 'Dragon's Blood'?
Sedum 'Dragon's Blood' is over by early August. These start as it finishes and carry the same spot on, so it never goes flat:
- Lilyturf: from early August to mid September, 16 in tall.
- Sedum 'Autumn Joy': from mid August to mid October, 24 in tall.
- Little bluestem 'Standing Ovation': from early August to mid September, 3½ ft tall.

Is sedum 'Dragon's Blood' good for bees and butterflies?
Sedum 'Dragon's Blood' is visited by pollinators, bees, butterflies and songbirds.
