# Blue Mountain Prairie Clover (*dalea ornata*)

The Blue Mountain Prairie Clover (Dalea ornata) is an eye-catching perennial wildflower native to the arid landscapes, sagebrush steppes, and rocky canyons of the Pacific Northwest. Part of the legume family, this beautiful plant produces vibrant, rose-purple flower spikes that rise gracefully above its textured, green foliage. Beyond its aesthetic appeal, it serves as an ecological anchor, stabilizing dry soils with its extensive taproot system and enriching the surrounding habitat through nitrogen fixation.

## Appearance

This species forms upright clumps between 15 to 50 centimeters tall, featuring compound leaves with 5 to 7 gland-dotted, lance-shaped leaflets. Its most striking feature is the dense, cone-shaped flower spike at the tip of each stem, packed with tiny pink-purple flowers that are supported by distinctly hairy, fuzzy calyces, giving the spike a soft, textured appearance.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Tracheophyta
- **Class:** Magnoliopsida
- **Order:** Fabales
- **Family:** Fabaceae
- **Genus:** Dalea

## Interesting facts

- Ecologists highly prize this plant for restoring degraded rangelands because its deep roots are excellent at preventing soil erosion.
- Its fuzzy flower spikes strongly resemble colorful, miniature bottle-brushes blooming in the desert.
- The name 'Blue Mountain' does not refer to the color of its flowers, but rather the Blue Mountains region of Oregon and Washington where it is natively found.

## Special abilities

- **Nitrogen Fixation:** Enriches impoverished soils by harboring symbiotic root bacteria that convert atmospheric nitrogen into usable plant nutrients.
- **Drought Endurance:** Utilizes a deep, robust taproot system to access moisture stored deep within the arid, rocky earth during hot summer months.
- **Herbivore Deterrence:** Features gland-dotted foliage that releases bitter chemical compounds to discourage grazing by generalist herbivores.

## Measurements & details

- **Length:** 15-50 cm
- **Lifespan:** 3-10 years

## Diet & Feeding

As a primary producer, this plant utilizes photosynthesis to generate energy from sunlight, carbon dioxide, and water while absorbing essential soil nutrients.

- **Primary Foods:** Sunlight, Carbon dioxide, Water, Soil minerals

## Ecological connections

- **Eaten by:** Greater Sage-Grouse (*Centrocercus urophasianus*) — The foliage and protein-rich seeds are consumed as food by native wildlife.
- **Mutualism:** [Alfalfa Leafcutter Bee](https://www.snappit.app/explore/alfalfa-leafcutter-bee) (*Megachile rotundata*) — Native bees visit the showy flower spikes to collect pollen and nectar, facilitating pollination.
- **Mutualism:** Rhizobium Bacteria (*Rhizobium leguminosarum*) — Symbiotic bacteria colonize the roots, providing nitrogen to the plant in exchange for carbohydrates.

## Safety

**Danger:** 1/5 · Very low
