The Härmastoft, first discovered by Swedish intergalactic explorers, requires a great deal of heat to bloom. The stiff, brushy plant has large buds which mimic the nests of the local Vogelsperling. The Vogelsperling are a very nurturing species of small birds, and upon seeing an untended nest, they will immediately begin caring for it. The body heat of the nesting bird allows the plant to bloom.
The relationship is not totally one-sided, as the blooms attract insects that the Vogelsperling feed upon.
The Härmastoft has flourished across its homeworld (MH-779) to many different biomes by adapting its coloring to match the nests of the subspecies of vogelsperling that inhabit the area.
