Calamus

The Calamus (Acorus calamus) is a species in the genus Acorus. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical coniferous forests within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Common Peony

<em>Paeonia officinalis</em>, the common peony, is a herbaceous perennial flowering plant in the family Paeoniaceae, widely cultivated for its large, showy flowers ranging from deep red to pink and white. In the wild, it typically grows in open woodlands, scrublands, and rocky hillsides across southern and central Europe, with native or naturalised populations documented in Austria, Belgium, the Czech Republic, France, Canada, and numerous other European and North American countries. The species prefers well-drained soils in partially shaded to open positions and produces large, deeply divided leaves alongside its ornamental blooms, which appear in late spring. <em>Paeonia officinalis</em> has a long history of medicinal and ornamental use spanning millennia, and numerous cultivated varieties have been developed. It is assessed as Least Concern on the IUCN Red List, reflecting stable populations in many parts of its native range, though wild populations can be locally threatened by over-collection, agricultural expansion, and habitat conversion. Biological traits such as average lifespan of individual plants, precise dimensions, and detailed dietary or metabolic data remain poorly documented in the scientific literature. The species plays a role in supporting pollinators, particularly beetles and bees that visit its flowers.
