Invasive in parts of North America. Self-seeds in warm climates, and seedlings revert to the vigorous wild type. Listed as invasive in many eastern states and regulated in New York. Check local guidance before planting. The planner never chooses it.

Where dwarf maiden grass 'Adagio' 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: specimen. A feature plant with a shape of its own. It stands alone with room around it, and repeats only at a distance.

It flowers earlier and more heavily than the tall kinds, which also means it sets more seed. The planner will not choose it; prairie dropseed and fountain grass give a similar shape.

Roughly when dwarf maiden grass 'Adagio' is in flower
Zone 5Late August to mid October
Zone 6Late August to mid October
Zone 7Mid August to mid October
Zone 8Mid August to mid October
Zone 9Early August to mid October

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 maiden grass 'Adagio' be planted?

2½ ft (75 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 3 ft (90 cm), so a group knits into one patch.

It grows 4 ft (120 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.

How many dwarf maiden grass 'Adagio' 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.

Is dwarf maiden grass 'Adagio' 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.

Mostly not. NC State lists it as resistant to deer. No plant is proof against a hungry deer in a hard winter, but this one is low on the menu.

Will dwarf maiden grass 'Adagio' spread?

It seeds itself about; the risk of it taking over is moderate. Self-seeds in warm climates, and seedlings revert to the vigorous wild type. Listed as invasive in many eastern states and regulated in New York. Check local guidance before planting.

Checked against NC State Extension. Flowering times are for zone 5: later in colder zones, earlier in warmer ones.

Check your local invasive species list before planting anything with a spread warning.
