The Alder is a native, fast growing, deciduous species that's particularly well suited to wet sites. Its young buds are a bit sticky (hence it's Latin name) but develop into a nice dark, glossy leaf - and generally where it is grown in wet sites, it keeps it's leaves in autumn for a considerably longer time than most other deciduous species. The other big advantage of Alder is that it's roots fix nitrogen in the soil - so it enhances soil quality over time and is especially useful in areas with poor soil quality. Alder has slender male, reddish brown catkins and a female fruit which is hard, darker in colour and shaped like a very small pine cone - these female fruits often stay on the bushes throughout most of winter and look very attractive. Flowers early March-late May. Grows 60cm+ per year. Supplied in 2 litre pots.
Potted Plants are a more developed plant as their root systems are not disturbed during the lifting and planting process. They can be planted year round and if necessary can be left in their pots for several weeks before planting if you are unsure as to when you will be able to get round to doing the work; all they need is a little water to keep them happy. As more mature plants you don’t need quite as many per metre as the bare root plants (normally 3 to 5 would suffice depending on how dense you require your hedge and how quickly you need it to look established). Pots are a great way to create a new hedge effect more quickly.
