Allium yosemitense, also known as the Yosemite Onion, is a species of wild onion native to the Sierra Nevada of California. It is a member of the Allium genus, which includes other well-known plants such as garlic, leek, and chive.

Description

Allium yosemitense is a perennial herb that grows from a bulb. It has a single, hollow, cylindrical leaf and a stem that can reach up to 40 cm in height. The flowers are typically white or pink and bloom in the summer. The plant is found in subalpine and alpine habitats, often in rocky or sandy soils.

Taxonomy

The Yosemite Onion was first described by botanist Estella Leopold in 1971. It is classified in the Amaryllidaceae family, within the Allioideae subfamily. The species name yosemitense refers to Yosemite National Park, where the plant is commonly found.

Distribution and habitat

Allium yosemitense is endemic to the Sierra Nevada in California, particularly in and around Yosemite National Park. It grows in subalpine and alpine habitats, often in rocky or sandy soils. The plant is adapted to the cold, dry conditions of its high-altitude habitat.

Conservation status

The Yosemite Onion is not currently listed as threatened or endangered. However, like many alpine plants, it may be vulnerable to the effects of climate change.

Uses

While not typically used in modern cuisine, the bulbs of Allium yosemitense were traditionally harvested by Native American tribes in the region for food.
