## Appearance

The Prairie Junegrass has slender, upright stems topped with a distinctive, spike-like flower head that shimmers with a silvery-green to purplish hue. Its narrow, grayish-green leaves grow in compact clumps, making it look like a neat tuft of hair in the landscape.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Tracheophyta
- **Class:** Liliopsida
- **Order:** Poales
- **Family:** Poaceae
- **Genus:** Koeleria

## Interesting facts

- Even though it's a grass, its shimmering flower head sometimes looks like tiny twinkling lights!
- Its scientific name, Koeleria macrantha, honors German botanist Georg Ludwig Koeler!
- Prairie Junegrass is called a 'bunchgrass' because it grows in neat, tight clumps, not spreading out.
- This grass is often one of the first native grasses to bloom on the prairie each year!

## Special abilities

- **Fire Rescuer:** Prairie Junegrass can bounce back quickly after prairie fires because its growing points are safely tucked underground, helping ecosystems recover.
- **Drought Warrior:** Prairie Junegrass has deep, fibrous roots that help it find water far below the surface, allowing it to survive long dry spells.
- **Soil Anchor:** Prairie Junegrass grows in dense clumps with strong roots that hold soil together, preventing erosion and keeping the ground healthy.

## Measurements & details

- **Height:** 10-60 cm
- **Bloom Season:** Late spring to early summer
