Radishes
Raphanus
Raphanus is the genus of the garden radish (Raphanus sativus) and wild radish (Raphanus raphanistrum), and it sits in the mustard family with cabbage and broccoli. These plants live one or two years. In cultivated forms the taproot swells into a round or long root in red, white, purple or black. Flowers have four petals, and the seed pods stay closed when dry. If one came up on its own in your yard, the rough lobed leaves and white, pink or pale yellow flowers are good clues, and a photo can tell you which one you have.
Wild Radish
Raphanus raphanistrum
Wild Radish (Raphanus raphanistrum) is a fast-growing annual in the Brassicaceae family, native to the Mediterranean basin and now naturalized worldwide. It thrives in disturbed soils, roadsides, and agricultural fields. The plant produces characteristic four-petaled flowers in white, yellow, or pink with dark veins, and its young leaves and flower buds are edible with a peppery flavor reminiscent of arugula. Despite being classified as a weed in many agricultural contexts, it holds ecological value as a pollinator plant and historical importance as a famine food.
Radish
Raphanus sativus
Raphanus sativus, commonly known as radish, is a fast-growing annual or biennial vegetable in the Brassicaceae family. Native to Asia, it has been cultivated for over 2,000 years across the world for its crisp, edible roots.

Andean Podocarp
Retrophyllum rospigliosii
The Andean Podocarp is a conifer found in the cloud forests of the Andes, from Venezuela and Colombia to Bolivia. It grows at altitudes between 1,400 and 3,300 m and can exceed 30 m in height, with records of up to 45 m. Its leaves are about 1 cm long and lie flat along the branches. There are male and female trees, and the seed matures from green to red or light yellow. The IUCN classifies it as vulnerable due to logging and the loss of Andean forest. In Peru, the name 'diablo fuerte' (strong devil) is also used for another tree, Prumnopitys harmsiana.
Knotweed
Reynoutria
Reynoutria is a genus of large, vigorous, deciduous perennial herbs in the family Polygonaceae, native to East Asia (Japan, China, Korea, Taiwan). The genus is best known for Reynoutria japonica (Japanese knotweed), one of the world's most aggressive invasive plants. Plants produce stout, bamboo-like hollow stems that can reach 2β4 metres in height, broad heart-shaped leaves, and dense clusters of tiny creamy-white flowers in late summer and autumn. Rhizomes are extraordinarily persistent, surviving temperatures as low as -35Β°C and capable of penetrating concrete foundations, walls, and drainage systems. In its native range, the genus is valued medicinally β particularly as Hu Zhang (tiger's cane) in Traditional Chinese Medicine β and young shoots are eaten as a vegetable.
Bohemian knotweed
Reynoutria Γ bohemica
Reynoutria Γ bohemica, commonly known as Bohemian knotweed, is a highly invasive hybrid perennial resulting from the natural cross between Japanese knotweed (R. japonica) and giant knotweed (R. sachalinensis). First identified in Bohemia (Czech Republic) in the late 19th century, it has since spread aggressively across Europe, North America, New Zealand, and beyond. The plant produces hollow, bamboo-like canes reaching 3β5 m in height and an underground rhizome network extending up to 7 m laterally and 3 m deep. These rhizomes can penetrate building foundations, drainage systems, flood defences, and road surfaces. Bohemian knotweed is listed among the world's 100 worst invasive species and is subject to legal controls in the UK, EU, and several US states. It outcompetes all native vegetation through rapid canopy closure and allelopathic root exudates that suppress surrounding plant growth.
Japanese Knotweed
Reynoutria japonica
Reynoutria japonica, commonly known as Japanese Knotweed, is a highly invasive perennial herbaceous plant native to East Asia. Classified as one of the world's worst invasive species by the IUCN, it forms dense thickets reaching 3 meters tall that outcompete native vegetation and cause significant structural damage to buildings, roads, and drainage systems through its aggressive rhizome network.
Giant Knotweed
Reynoutria sachalinensis
Giant knotweed (Reynoutria sachalinensis) is one of the world's most aggressive invasive plants, native to Sakhalin Island, Japan, and eastern Asia. It produces towering hollow stems that can exceed 4 metres in height, with enormous heart-shaped leaves up to 40 cm wide. In late summer, it bears dense clusters of tiny creamy-white flowers that attract pollinators. Introduced to Europe and North America in the 19th century as an ornamental and fodder plant, it has since escaped cultivation and colonised riverbanks, roadsides, waste ground, and disturbed habitats on a massive scale. Its rhizome system penetrates deep into the soil and can regenerate from fragments as small as 1 cm, making eradication extraordinarily difficult. It outcompetes native vegetation by shading the ground and releasing allelopathic compounds that suppress other plants. Listed among the 100 worst invasive species globally, it poses serious risks to biodiversity, infrastructure, and watercourses.
Buckthorn
Rhamnus
Rhamnus is a genus of roughly 100 species of deciduous and evergreen shrubs and small trees in the family Rhamnaceae, commonly known as buckthorns. Native across the temperate Northern Hemisphere, including Europe, North Africa, temperate Asia, and North America, the genus includes cold-hardy deciduous species such as common buckthorn (R. cathartica) and alder buckthorn (R. frangula), as well as evergreen Mediterranean and West Coast species like R. alaternus and R. croceus. Buckthorns typically bear small, inconspicuous greenish-yellow flowers in spring, followed by clusters of small black or reddish berry-like drupes that are an important food source for birds. Several species carry thorny branch tips, hence the common name, and many are grown as hedging, screening, or wildlife shrubs, though a few, notably R. cathartica, are considered invasive outside their native range.
Common Buckthorn
Rhamnus cathartica
Common Buckthorn (Rhamnus cathartica) is a deciduous shrub or small tree in the Rhamnaceae family, native to Europe and Western Asia. It features thorny, crooked branches and glossy black berries ripening in autumn. While ecologically valuable in its native range, it is considered highly invasive in North America, forming dense thickets that outcompete native vegetation. WARNING: berries are TOXIC β they contain anthraquinones and emodin causing severe laxative effects. Toxic to cats, dogs, and humans.
