Diplacus graniticola

Granite-crack monkeyflower

Family: Phrymaceae · Type: annual · Native

Granite-crack monkeyflower is a California native annual found in granite rock formations, particularly in cracks and crevices at elevations of 300 to 2,100 meters. Flowering from April to September, this plant produces striking pink to magenta flowers with a yellow throat, delicate blossoms nestled among rocky terrain. Growing with slender stems 6 to 15 centimeters tall, the plant is densely covered in glandular hairs that give it a soft, fuzzy appearance. Its leaves are 20 to 40 millimeters long, ranging from lanceolate to ovate, providing a compact green framework for the vibrant flowers. The small flowers emerge on short 1 to 3 millimeter pedicels, with calyxes 8 to 12 millimeters long that are dark-ribbed and glandular-hairy.
