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.

Clusterspike False Indigo

Amorpha crenulata, known as clusterspike false indigo or crenulate lead plant, is a critically endangered flowering shrub in the family Fabaceae with a highly restricted distribution confined to Miami-Dade County in southern Florida, USA. This species represents one of North America's rarest plants, with remaining populations numbering in the hundreds of individuals occurring in pine rockland habitat, an ecosystem itself ranked among the most imperiled in the United States. Pine rocklands are fire-dependent communities on exposed oolitic limestone, characterized by an open canopy of slash pine over diverse understory, and have been reduced to less than two percent of their historical extent by urban development in the Miami metropolitan area. Amorpha crenulata produces elongated spikes of small purple flowers typical of the genus and was historically more widespread across the Miami Rock Ridge before land development eliminated most habitat. Current populations exist primarily within Everglades National Park and a few private preserves. Its Critically Endangered status reflects the tiny remaining population, extreme habitat restriction, ongoing threats from urbanization, altered fire regimes, and sea-level rise that threatens low-elevation limestone habitats. Conservation efforts focus on habitat protection, controlled burning to maintain pine rockland structure, and ex situ seed banking.
