The Bloom of Echoes, or Swokurwll, resembles both a hanging orchid and a weeping willow tree. It possesses expansive, thick petals and sepals that radiate from a central point which connect to the root network above. Each petal sprouts many willow branch-like tendrils that trail towards the ground, forming veils of glowing strands. It is a lithophyte, drawing nutrients from its environment.
As with each of the flora the clans of Pandora use to access Eywa, these numerous branches are neural connectors which Na’vi use to upload their own memories and also commune with the memories of their ancestors. A Swokurwll is found in the Chamber of Echoes, a serene cave where the Zeswa come to commune and hold ceremonies.
