climbing groundsel

Climbing Groundsel, Senecio angulatus, is a woody, scrambling perennial vine in the family Asteraceae native to South Africa, particularly the Western and Eastern Cape provinces, where it grows in coastal scrub, fynbos margins, and forest edges. The species produces yellow daisy-like flower heads in terminal clusters from autumn through spring, which are followed by fluffy white achenes dispersed by wind. Climbing Groundsel has become widely naturalized and highly invasive in many parts of the world where it has been introduced as a garden ornamental, including Australia, New Zealand, and parts of Europe. In Australia, it is listed as a major environmental weed in southeastern states, particularly New South Wales and Victoria, where it invades coastal heath, dry sclerophyll forest, and urban bush remnants, smothering native vegetation with dense scrambling growth. The plant regenerates readily from stem fragments and produces abundant wind-dispersed seeds. Control in invaded habitats requires sustained effort combining physical removal and herbicide application. In its native South African range, Senecio angulatus is part of diverse coastal scrub communities and is not considered threatened. The genus Senecio is one of the largest flowering plant genera in the world, with species ranging from annuals to giant tree groundsels in tropical alpine zones.

Compact Thread-leaf Century Plant

<em>Agave microceps</em>, the compact thread-leaf century plant, is a perennial succulent in the family Asparagaceae native to Mexico, representing one of the smaller members of the ecologically and culturally significant agave genus. Agaves are iconic succulents of arid and semi-arid regions characterised by a rosette of thick, fibrous leaves typically edged with teeth and terminating in a sharp spine. <em>Agave microceps</em> typically forms compact, densely-leaved rosettes with notably narrow, thread-margined leaves, distinguishing it from larger agave species. It inhabits rocky slopes, dry grasslands, and scrublands in its native Mexican range, adapted to well-drained soils and periods of seasonal drought. Like all agaves, it is monocarpic, flowering once after many years of vegetative growth before dying, producing a tall flower spike that provides food resources for bats, hummingbirds, and insects. The species is classified as Least Concern by the IUCN, indicating a stable population without critical current threats, though many agave species face pressure from illegal collection for the horticultural trade and habitat conversion. Agaves play important roles in native ecosystems as food sources for specialist pollinators and as habitat elements on rocky hillsides. Biological traits including average lifespan in the wild, precise rosette dimensions, and population data remain poorly documented for this species compared to more commercially important agaves.
