This is a strategy used by many plants to protect their reproductive parts from the intense heat and potential damage from the sun.
Purple Owl’s Clover (Castilleja exserta)
Purple Owl’s Clover is an annual wildflower that decorates California’s grasslands and desert washes with its rich, pink to purple, feathery-looking blooms from March to June.
This plant is a hemiparasite, meaning it can extract water and nutrients from other plants, enabling it to survive in poor soil conditions.
The “feathers” are actually colorful bracts, specialized leaves that surround the small, less noticeable true flowers.
This clever adaptation helps attract pollinators and gives the plant its distinctive appearance.
Yellow Mariposa Lily (Calochortus luteus)
The Yellow Mariposa Lily is a perennial wildflower that graces the oak woodlands and grassy hillsides of California with its bright, sunny blooms.
