Diffuse Spineflower
Scientific name:
Chorizanthe diffusa
Family: Knotweed or Polygonaceae
Blooms: Apr–July
Plant Height: < 10 cm

About: This plant is prostrate to spreading and appears greenish/white. It is relatively common and may be found with Monterey Spine flower. It can be distinguished by its yellow-throated white flowers, and generally pure white involucral membranes (occasionally pink or purple). These are not continuous (i.e. spanning the entire space between the ribs), but ovate to round at their base, abruptly narrowing to a long slender tip. The involucral teeth have hooked awns.
