Alder Buckthorn

Rhamnus frangula / Frangula alnus

Alder buckthorn has dark brown outer bark but the inner bark is bright yellow when exposed. Unlike purging buckthorn, the branches and stems are smooth and thornless. The twigs are smooth and straight, purple-brown in colour and have fine white streaks. Tiny white star-shaped flowers grow in clusters in spring. Alder buckthorn is used to make gunpowder, pigments and dyes.

Alder Buckthorn estimated full grown height:

Up to 6m.

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, please do not worry 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:

Alder buckthorn leaves are the main food plant of the brimstone butterfly. The flowers are valuable for bees, and the fruit is an important food source for birds, particularly thrushes.

Alder Buckthorn preferred soil type or environmental conditions:

It grows best in wet soils and open woods, thriving in scrub, hedgerows, wet heathland, river banks and bogs. Although it prefers acidic soils, it can grow on neutral soils as well. 

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 they are all coded and batched so that we can track each individual tree.

Planting information:

As a rough guide, trees are usually planted at around 2m intervals but please take into account the final size of the tree and be aware of buildings, services and other plants nearby to ensure that damage cannot occur from the roots and canopy as the tree grows.

Oct-Feb - This is the best time of year for planting trees and your sapling is dormant, as long as it is kept free from frost and wind as well as being kept moist and in light conditions then it will last a few weeks before planting.

Mar-Sept - Your sapling is growing fast and will need planting as soon as possible. Planting it immediately will ensure it does not dry out, lose nutrients etc.

On-going care requirements:

Once planted, your tree will need some care and attention for a few years; this will mainly be weeding around the base to reduce the competition for nutrients and ensuring your tree has enough water. For more information about caring for your trees, click here.

Delivery information: 

Free delivery is available for all tree orders but please allow up to 7-10 days for your delivery to arrive. You will receive a cell grown sapling, ranging from approximately 15cm-60cm in height. 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, please do not worry once it has been planted it should pick up quickly. 

Please note that recent changes to regulations mean we are, unfortunately, currently unable to ship our trees to Northern Ireland. We apologise for any inconvenience caused.
