Brickellia mosieri, the Florida brickell-bush, is a North American herbaceous plant [1] in the family Asteraceae.

[2] It grows in Pine Rocklands in Florida, preferring low-nutrient sand close to sea level.

[1] This makes it impossible to safely freeze the seeds of the Florida brickell-bush for long-term storage.

No information is available on the age of sexual maturity, growth rate, or exact seed characteristics of the Florida brickell-bush.

The Florida brickell-bush is a plant and as such it is autotrophic and photosynthesizes to produce glucose (a type of sugar) that is used for nutrition.

Several species of butterflies are suspected as pollinators due to the shape of the Florida brickell-bush's flowers, which are suitable for pollination by bees, butterflies, or both[8] The Florida brickell-bush is known to grow in low-nutrient sand close to sea level.

The Florida brickell-bush also benefits from the fires, which stop other plant species from growing in the same area and taking over.

A study found that this plant grows in open shrub canopies which allow sunlight to reach this species.

It is mainly endemic to Pine Rocklands, found on the Miami Rock Ridge in central and southern Miami-Dade County - right outside of the everglades national park.

There has been a great decline in the population size of the Florida brickell-bush which has led to it being listed as endangered.

According to ECOS (Environmental Conservation Online System), the total population of the Florida brickell-bush has declined by 50% since 1999, leading to the decision to list it as endangered.

[7][6] The primary threats to the Florida brickell-bush are habitat destruction, fragmentation, and modification due to development, fire suppression, invasive plants, and sea level rise.

Sea level rise is a significant threat to the Florida brickell-bush, as large areas of coastal and low-lying South Florida (where it is found) are predicted to flood, be lost to sea level rise in the next 100 years and become more vulnerable to storms.

Sea level rising will damage and destroy coastal habitat and modify areas like Pine Rocklands where the Florida brickell-bush grows, causing catastrophic results for this plant.

Burma reed grows rapidly and shades the Florida brickell-bush plant, posing a threat to its survival.
