Western Paintbrush
castilleja occidentalis
The Western Paintbrush (Castilleja occidentalis) is a captivating alpine wildflower that adds splashes of pale yellow, cream, and sometimes purplish hues to the high-elevation meadows of Western North America. Thriving in the harsh, windswept environments of the subalpine and alpine tundra, this resilient perennial is a master of survival. What makes it particularly fascinating is its hemi-parasitic lifestyle. While it is fully capable of photosynthesis, it stealthily taps into the root systems of neighboring grasses, sedges, or sagebrush to secure water and essential nutrients, giving it an evolutionary edge in nutrient-poor mountain soils.
生息地: Found in alpine tundra, gravelly slopes, and moist subalpine meadows high in the Rocky Mountains.
外見
Standing relatively short at 10 to 30 centimeters tall, the Western Paintbrush features cluster-like terminal spikes adorned with colorful bracts. These bracts, which are often mistaken for petals, range from pale greenish-yellow to cream and occasionally tinged with purple, concealing the small, inconspicuous green true flowers within. Its leaves are lance-shaped, alternating along unbranched stems, and lack the deep lobes seen in some other paintbrush species. The entire plant is often covered in fine, soft hairs, a physical adaptation that helps conserve moisture in dry alpine winds.

おもしろい事実
Because they are hemi-parasites, trying to transplant these wildflowers into a home garden almost always fails because they cannot survive without their host plants.
Despite their bright, flower-like appearance, the colorful parts of the Western Paintbrush are actually modified leaves called bracts.
The scientific genus name, Castilleja, honors Domingo Castillejo, an 18th-century Spanish botanist and instructor.
特殊能力
能力
Root Parasitism
It utilizes specialized underground root connections called haustoria to penetrate and siphon water and mineral nutrients from neighboring host plants.
能力
Alpine Antifreeze
Accumulates high concentrations of cellular solutes and is covered in fine hairs to prevent frost damage during sudden alpine temperature drops.
能力
Selenium Accumulation
Absorbs and concentrates selenium from alpine soils, making itself highly distasteful and toxic to many potential herbivores.
サイズと詳細
- 長さ
- 10-30 cm
- 寿命
- 3-10 年
食性と食事
As a hemi-parasite, it generates energy via photosynthesis while stealing water and mineral nutrients from the roots of nearby host plants.
年齢による違い: Seedlings must rely on their own limited resources until they successfully establish a parasitic connection with a host plant's roots.
主な食物
- Sunlight
- Water stolen from host roots
- Soil minerals from host roots
- Carbon dioxide
