Effloresce refers to the process where a substance, typically a salt, forms a crystalline structure on the surface of a material, often due to evaporation of water. This phenomenon is commonly observed in building materials like concrete and brick, where moisture rises and evaporates, leaving behind white, powdery deposits. The term can also describe the blooming or flowering of plants, particularly in the context of botany. In this sense, efflorescence signifies the period when flowers emerge and display their colors, contributing to the plant's reproductive cycle. Both meanings highlight the idea of transformation and emergence.
