Purging Buckthorn (Rhamnus cathartica)

Common or Purging Buckthorn, Rhamnus cathartica, is an upright, spiny shrub/small tree (growing to 10m if left alone), usually found in scrub and hedgerows on chalky soil. Its black berries act as what Richard Mabey in Flora Britannica describes as a "fierce" purgative. I wonder if he tried them. It's an undervalued, healthy looking plant with a nice habit, and valuable for wildlife (see below). Like all the native plants we sell, our buckthorns are UK grown from seed harvested here.

Purging Buckthorn (Rhamnus cathartica)

Both Purging and Alder Buckthorn are the only foodplants of the Brimstone butterfly. Purging Buckthorn prefers drier and more calcareous spots than the damp loving Alder Buckthorn, however. It's also not hermaphrodite, but it can be tricky to tell the two plants apart; look for the leaves, which if in pairs on the stem mean you're looking at Common buckthorn. I guess it also looks not a million miles away from Cornus sanguinea, Common dogwood.

Buckthorn is a good hedging plant; put one in a hedge facing South or in any sheltered position and you will find yourself breeding Brimstones sooner rather than later.

Like all our native plants, the Alder buckthorn we sell is British grown and grown from seed from plants growing here naturally.

Suppliers: Perrie Hale Forest Nursery, RV Roger, British Hardwood Trees

Our Rhamnus cathartica plants are all bare root, and are consequently available for delivery from November until March ( please ask if you are interested in pot grown plants). During the lifting season there may be up to a month's delay between placing the order and dispatching, due to weather conditions or pressure of orders, which are dealt with in date sequence. Orders for Rhamnus cathartica placed between March and September are confirmed in October ready for dispatch from November.
