Description

Dwarf Woolly-heads are a small, hairy, annual plant that grows up to 5 cm tall. It has short, opposite leaves that are 5 to 25 mm long. The upper leaves usually surpass the flower heads, which are copiously woolly and really easy to see.

Habitat

Dwarf Woolly-heads are found in the clay soil of vernal pools in large forest openings dominated by species of popcornflower and Close-flowered Knotweed. It is also found in shallow, temporarily flooded depressions and ponds, in the same type of soils, wet in spring but dried out and compacted in summer.

Threats

-Restricted to small areas of suitable habitat
-Habitat destruction due to changes in grazing, hydrology practices, and ATV use
-Invasive plants
-Climate change reduces the frequency of flooding for suitable sites
