Living Rock Cactus
Ariocarpus
Ariocarpus is a genus of slow-growing, spineless cacti native to the limestone deserts of northern and central Mexico and southern Texas. Its thick, star-shaped tubercles are covered in a grey-brown, warty skin that mimics the surrounding rock and gravel almost perfectly, a camouflage strategy that protects it from grazing animals in the wild. Most of the plant body sits at or below soil level, anchored by a large taproot, with only the crown visible above ground. Woolly tufts of hair nestle between the tubercles, and in late summer or autumn mature plants produce showy white, pink, magenta, or purple daisy-like flowers from the center of the rosette.
Arnica
Arnica montana
Arnica montana is a perennial herbaceous plant native to the mountainous regions of central and southern Europe, including the Alps, Pyrenees, and Carpathians. Revered for centuries in European folk medicine, it produces bright yellow, daisy-like flowers in summer. It is legally protected in several European countries due to overharvesting. The entire plant is toxic if ingested, but flower extracts are widely used in topical preparations to relieve bruising, muscle soreness, and inflammation.

It is a species with a very specific ecological niche, essential for the study of mycology and forest biodiversity.
gray mangrove
Avicennia marina
Avicennia marina, the gray mangrove, is a salt-tolerant coastal tree native to the intertidal zones of the Indo-Pacific region, spanning East Africa, the Arabian Gulf, South and Southeast Asia, and Australasia. It grows as a shrub or tree from 3 to 14 meters tall, with smooth grey bark, leathery leaves that are glossy dark green above and silvery-grey below (dusted with excreted salt crystals), and small white to pale yellow flowers. Its most distinctive feature is a network of pencil-like breathing roots (pneumatophores) that rise from the mud to draw oxygen in waterlogged, anaerobic sediment. A pioneer species, it colonizes newly formed mudflats and produces viviparous propagules that germinate while still attached to the parent tree before dropping and rooting in the substrate. Extremely tolerant of salinity, tidal flooding and heat, it is rarely cultivated outside coastal restoration, aquaculture, and specialist paludarium or bonsai settings.
Sea Poison Tree
Barringtonia
Barringtonia is a genus of approximately 73 species of tropical evergreen trees and shrubs in the family Lecythidaceae. Native to coastal and freshwater habitats across Africa, South and Southeast Asia, Australia, and Pacific and Indian Ocean islands.
