Pyrophila resurgensWildfire Flower

On the hill crests, Pyrophila was most abundant only in shallow acidic soils weathered from sandstone. It was sparse on sticky shale slopes, and in iron-red hollows it produced mostly leaves. Soil too poor in ordinary years receives a brief rise of phosphorus and potassium after ash settles. The plant appears to use that short reprieve before its competitors return.

After the third week following fire, the flowers collapse quickly and the shoots vanish among dry grass litter. By the next month, the only evidence is a narrow ripe capsule. Its scarcity in collections is therefore unsurprising. In old herbarium packets, it may have been gathered once as a related post-fire annual, then separated from its label into another bundle.

The stands bloom all at once, yet almost no pollen carrier is seen by day. The deep red corolla darkens toward evening, and the anthers loosen before dawn, leaving room for visits by small nocturnal moths. Even isolated plants, however, set a few fruits. In the brief post-fire season, the plant likely waits for crossing but can finally self-pollinate to maintain its buried seed bank.
