Plant of the day: Marin dwarf flax

Sprays of delicate flowers are dense on a grassy hillsides of Ring Mountain. Pink buds open into slightly disheveled white flowers–the petals are slightly disarranged and appear delicate, as if loosely attached.

This diminutive beauty is Marin dwarf flax (Hesperolinon congestum), which grows only on the Tiburon Penninusla and the San Francisco Peninsula. It is only found on serpentine soils, and can be distinguished from other local types of dwarf flax because the petals are more than 5 mm long, and the sepals are covered with fine hairs. Leaves are small and needlelike.
