This plant is similar to common buckthorn, but the stems are more stout and the leaves are longer.

Two widespread invasive species are established in the park, common buckthorn and reed canary grass.

The exotic shrubs that have become rampant are common buckthorn and common privet.

In that region the alternate host, common buckthorn (Rhamnus cathartica), grows abundantly in shelter belts and riparian areas.

Common Buckthorn (Rhamnus cathartica; Dygioji šunobelė)

In the limestone mountains of Andalusia a detectable role is played by thickets pluvilunares and hummocks of common buckthorn (Rhamnus cathartica).

Two confirmed Rhamnus species that support overwintering of soybean aphids in North America are common buckthorn (Rhamnus cathartica) of exotic origin and alderleaf buckthorn (Rhamnus alnifolia) of native origin.

The Purging Buckthorn or Common Buckthorn (R. cathartica) is a widespread European native species, in the past used as a purgative, though its toxicity makes this a very risky herbal medicine and it is no longer used.

The eggs are laid singly on the leaves of either Common Buckthorn (Rhamnus cathartica) or Alder Buckthorn (Rhamnus frangula) - the only two food plants - and females will wander far and wide in search for these particular shrubs.

Rhamnus cathartica (Buckthorn, Common Buckthorn or Purging Buckthorn), is a species in the family Rhamnaceae, native to Europe, northwest Africa, and western Asia, from the central British Isles south to Morocco, and east to Kyrgyzstan.

Due to the very limited historical and current distribution of E. propullans, the primary threats include development and flooding along the floodplains and ridges where it currently exists, trampling and recreational use impacts, as well as habitat changes brought on by invasive species such as common Buckthorn (Rhamnus cathartica).

European buckthorn (Rhamnus cathartica) is a particularly aggressive invader in these degraded oak habitats.

Rhamnus cathartica (I)

In that region the alternate host, common buckthorn (Rhamnus cathartica), grows abundantly in shelter belts and riparian areas.

Eurasian buckthorn (Rhamnus cathartica and R. frangula)

Common Buckthorn (Rhamnus cathartica; Dygioji šunobelė)

Henry's Elfin is increasing in New England because of an introduced buckthorn (Rhamnus cathartica) it now uses as a host plant.

F. alnus and the related species Rhamnus cathartica have been banned from sale, transport, or import to Minnesota and Illinois.

The larvae mine the leaves of Rhamnus species, including Rhamnus cathartica as well as Frangula alnus.

In the limestone mountains of Andalusia a detectable role is played by thickets pluvilunares and hummocks of common buckthorn (Rhamnus cathartica).

Rhamnus frangula is one of just two food plants (the other being Rhamnus cathartica) used by the Common Brimstone butterfly Gonepteryx rhamni.

The larvae mainly feed on Dogwood, Rhamnus frangula, Hedera helix, Rhamnus cathartica, Grape and Honeysuckle.

The larvae feed on Prunus padus, Rhamnus species (including Rhamnus frangula and Rhamnus cathartica) and Fraxinus excelsior.

Two confirmed Rhamnus species that support overwintering of soybean aphids in North America are common buckthorn (Rhamnus cathartica) of exotic origin and alderleaf buckthorn (Rhamnus alnifolia) of native origin.
