A bed built around dwarf fountain grass 'Hameln'
The planner designed this bed around dwarf fountain grass 'Hameln' when this page was made: a 12 × 6 ft (3.7 × 1.8 m) naturalistic planting in zone 6, full sun. It chose the other plants from the 966 that suit those conditions, and says below why dwarf fountain grass 'Hameln' stands where it does.
The plants
- 1 Dwarf fountain grass 'Hameln' × 1, cream
- 2 Winter heath × 10, pink
- 3 Coral bells 'Firefly' × 8, red
- 4 Swamp milkweed 'Ice Ballet' × 3, white
- 5 Switchgrass 'Cheyenne Sky' × 5, purple
- 6 Palm sedge × 3, green leaves
- 7 Grecian windflower × 12, blue
- 8 Hyacinth × 12, yellow
Why this plant
- The only plumes. The others are bells, airy sprays, flat plates and others. Shape reads at a distance, where colours blur.
- The only cream. Cream sits between stronger colours and calms them.
Why here
- In the middle. At 2½ ft it is seen over winter heath (10 in) in front of it.
- One plant, alone. A feature plant is seen as an object, and needs clear ground around it.
Why now
- In flower for 9 weeks. From late July to mid September.
- Part of the bed's peak. With coral bells 'Firefly', swamp milkweed 'Ice Ballet' and switchgrass 'Cheyenne Sky' in late July: 4 kinds at once. No week has more.
- Stands through winter. Left uncut, it holds its shape until March, when the perennials have gone.
Planned as a naturalistic planting: low grasses and groundcovers, the matrix, make up 62% of the planted ground. The flowering is at its height in late July, with 4 kinds out together. Switchgrass 'Cheyenne Sky' and swamp milkweed 'Ice Ballet' anchor the back corners of the bed: the tallest plants on the plan stand there.
The planner's own design check: 12 Excellent, 4 Good, 1 Satisfactory. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

When does dwarf fountain grass 'Hameln' flower in my zone?

| Zone 8 | Mid July to mid September |

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 dwarf fountain grass 'Hameln' be planted?
2½ ft (75 cm) apart, from the middle of one plant to the middle of the next. That is about its full width, so each plant keeps its own outline.
It grows 2½ ft (75 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.
How many dwarf fountain grass 'Hameln' plants do I need?
At 2½ ft apart, set out in staggered rows:
- 2 to fill 10 square feet (about 1 m²)
- 5 for a single row 10 ft (3 m) long
- 6 to fill a 4 × 8 ft bed on its own
In a mixed border, plant it as one, with clear ground around it: a feature plant is seen as an object, and a group of them is a thicket.
In the bed above, the planner used one in one group.
Is dwarf fountain grass 'Hameln' 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.

- Blue grama 'Blonde Ambition': the same colour; a drift, not a specimen, 6 in narrower.
- Arkansas bluestar: the same job in a bed; 6 in taller, flowers mid May to early June.
