A fast growing, deciduous native plant with mauve-bloomed buds opening to shiny, dark green, racquet-shaped leaves. Male and female catkins February to April, female catkins turning to attractive false cones, providing plenty of bird food the following spring. Ideal for very wet situations, and is useful for preventing soil erosion and fixing nitrogen. It is very useful where rabbits or stock may damage the bark as it is rarely eaten.

Bare-Root Plants (Transplants)

Bare-root plants are sold without a pot/soil around the roots. This is a more cost effective and environmentally friendly way of growing plants. To ensure the best plant health we do not store our plants in cold storage, but they are left in our field or plant beds until they are ready for packing or collection.

Transplanted plants have been lifted from the ground and replanted. This encourages a better fibrous root system and makes the plant stronger and bushier.


Bare rooted plants are only available when the plants are dormant (typically from late November to March).

If a plant is currently out of stock because it is out of season (for example, bare rooted plants in summer) or we have sold out but we are expecting more to be available you can pre-order the plant. We only charge credit/debit cards when an order is despatched, not when an order is placed.

Planting Distances for planting as a Hedge

We recommend planting Alder, Common in a single row 60cm/2ft apart.

To calculate the number of plants needed for a length of hedging, click on Planting Distance Calculator above.

Plant Sizes for Hedging

We do not recommend the following size for hedging as these taller plants are likely to have dropped their bottom branches creating a gap at the base of the hedge:

Planting Guide & RootGrow

We recommend planting with RootGrow. The recommended amount for RootGrow for an order will be shown in your shopping basket.

We will send out a planting guide with your order, you also can find a guide to planting here.


Hedging - As a general rule, plants grown for hedging need pruning to encourage side branching. Usually the harder a plant is pruned the bushier it will be. If they are not pruned there is a danger that the hedges will be thin and bare at the base and that the tips of the plants will die back. If the plant is naturally bushy, less or sometimes no pruning will be needed to achieve a dense hedge.

Alder, Common: Cut back by about one third the leading and long side shoots and repeat during the second winter.
