Black Bent

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

Common Sundrops

<em>Oenothera fruticosa</em>, the common sundrops, is a perennial flowering plant in the family Onagraceae, order Myrtales. It is native to eastern North America and has been introduced and naturalized in parts of Europe, including Czech Republic, Norway, and Sweden, as well as in Japan. The species typically inhabits open, sunny habitats such as meadows, roadsides, dry slopes, and disturbed areas, preferring well-drained soils. <em>Oenothera fruticosa</em> bears bright yellow, four-petalled flowers that bloom in late spring and early summer, attracting a range of pollinators including bees and butterflies. Unlike many evening primroses in the genus, sundrops are day-blooming. The plant spreads both by seed and by vegetative runners, forming colonies in suitable habitat. Biological traits including average individual lifespan, precise height measurements, and specific herbivore associations remain poorly documented at the species level. <em>Oenothera fruticosa</em> has not been formally assessed by the IUCN, though it is generally considered a locally common species without significant conservation concerns, and its naturalized populations in Europe are typically stable.
