- Mythical asp — A mythological monster or legendary beast shaped like a winged serpent or dragon, present in medieval bestiaries, ancient religious texts (Psalter), and Eastern European folklore; (figuratively, in common language) a wicked, treacherous, malicious, and sharp-tongued woman who structurally sows strife and conflict through gossip or venomous manipulations.
- Aspidistra — Popular and scientific name for an ornamental perennial herbaceous plant, native to the shaded forests of East Asia, frequently cultivated as a houseplant due to its exceptional resistance to adverse conditions; it is characterized by large, lanceolate, dark green, glossy leaves that grow directly from a subterranean rhizome, also known by the metaphorical name 'cast-iron plant' due to its capacity to survive in spaces with dim light, dry air, or high temperature fluctuations.
- Aspidistra elatior — The scientific name of the aspidistra, a perennial herbaceous plant in the Asparagaceae family, native to the shaded forests of Japan and Taiwan; it is globally cultivated as an indoor ornamental plant, famous for its legendary resistance to neglect, low light, dust, and temperature fluctuations, which is why it is popularly called the 'cast-iron plant'.
