Phacelia corymbosa is a species of flowering plant known by the common name serpentine phacelia. It is native to the mountains of southern Oregon and northern California, where it grows in serpentine soils. It is a perennial herb growing mostly erect to a maximum height near 40 centimeters. It is very glandular and coated in stiff hairs. The lower leaves are up to 15 centimeters long and sometimes divided into smaller leaflets; leaves higher on the plant are smaller and generally undivided. The hairy inflorescence is a coiling cluster of cylindrical white flowers, each about half a centimeter long and with five long protruding stamens.
How to keep Phacelia Corymbosa.
Pruning
Pruning serpentine phacelia from early to late spring promotes its healthy growth and flowering. To boost its vigor and improve air circulation, remove any spent blooms and damaged parts. Regular maintenance helps the plant maintain a compact form, which is perfect for rock gardens or wildflower displays. This is supported by horticultural experts, such as those at the RHS.
