Purging buckthorn is named after the laxative effects its berries induce when eaten. It is a source of food and shelter for a range of wildlife and its dense growth attracts bids looking for nesting sites.
Estimate full grown height: 8-10 metres, growing an estimated 30cm each year.
Purchase size and growth: These trees are cell-grown saplings, ranging from approximately 15cm-60cm in height. Cell grown trees can be planted all year round in most situations as long as they are given the correct care. Please be aware that depending upon the time of year you receive your sapling (particularly early spring) it may not look very perky upon arrival, but please do not worry, as once it has been planted it should pick up quickly.
Due to excellent growing conditions, some of our saplings are now slightly bigger than 60cm. This means some customers may receive a sapling that is up to 80cm tall. If you do receive a taller sapling, it will arrive with a slight curve in the top of the stem in order to fit it into the box. This should straighten out once planted, usually within four weeks. No matter which size you'll receive, all of our saplings are healthy and should grow into strong, sturdy trees. Unfortunately, we cannot determine which customers will receive the taller saplings as they are chosen at random.
Value to wildlife: Purging buckthorn is the main food plant of the brimstone butterfly, whose caterpillars eat the leaves, while its flowers provide a source of pollen and nectar for bees and other insects. Its dense growth also makes the tree a valuable nesting site for birds.
Preferred soil type or environmental conditions: Purging buckthorn is a hardy tree and grows well in most soils, in shade or sunlight.
UK and Ireland Sourced and Grown (UKISG): Every sapling that we provide is UK and Ireland sourced and grown to minimise the risk of importing and spreading tree pests and diseases. Seeds are collected and stored in the UK and Ireland, and they are all coded and batched so that we can track each individual tree.
