Cut Leaved Alder Alnus Glutinosa Imperialis
A very ornamental form of Alder (not the ornamental sense that you could put it on the mantle piece next to the cheap tat your Mother In-law got you last Christmas). It has fine and deeply cut leaves making it a great specimen tree. Used in parks and gardens for these very ornamental qualities and has a high resistance to urban pollution. It has been said that it gives an ornamental appearance but we don't think it looks anything like a Ninja.
Considered a fast growing tree suitable for almost any soil except chalk and will perform well in damp or boggy sites. At the time of writing the Cut Leaved Alnus Glutinosa Imperialis held the RHS Award Of Garden Merit which basically means it performs very well compared to other Alder trees.
Alnus Glutinosa Imperialis has been used for making boats, clogs, gun powder charcoal and treatments for rheumatism. So if you have ideas of building a navy and invading a wooden shoe wearing country while waving muskets and winning hearts and minds with those suffering inflamed joints, then this is the tree for you.
Feel free to severely prune to shape or promote new growth as it will shrug its branches and just grow more. Will tolerate full sun and shade positions with characteristics likely to attract wildlife.
Fully UK hardy so you can plant almost anywhere in the UK and not worry about it being killed of by the cold.

Girth 16-18cm : Rootball, Standard, roughly 480-540cm tall. Buy Nov to Mar only.
Rootball means it will not come in a pot but will have the roots wrapped which you need to remove before planting.
Standard and Half Standard means lollipop shape. There is more clear stem with a Standard.
Feathered trees are single stem trees with branches starting low to the ground.
Once an Alnus Glutinosa Imperialis gets over around 200cm then girth is the most accurate way to measure maturity and therefore value for money. For every girth measurement increment, the canopy will be wider, thicker, bushier and the root system larger. You can notice this in potted versions because the size increases with maturity. As a very general rule, each one cm girth measurement represents 12-18months growing and 30cm growth but there is wide variation even within the same batch of trees and heights are only a guideline. Feathered and multistem options are measured by height.

Dear Alan, The alder (Cut Leaved Alder Alnus Glutinosa Imperialis) arrived in tip top condition, so thank you very much. Best wishes Rachel 0821
Just have to say thank you and a big wow for the trees ordered from your fantastic site. Great communication re order and many thanks for the elegant Alnus glutinosa - what a lovely surprise. The golden willow looks very much at home in our lower somewhat damp lower paddock. The packaging was amazing and am sure it is an art installation in its own right. Will be ordering again soon as we have a large shrubbery to plan. Cheers Chris 0815

Ornamental Tree Roots In The Shade e.g. Behind A Fence
It is more important that that foliage (posh term for leaves) receives the sunlight than the roots. So if the canopy of your ornamental tree can sunbathe but the bottom of your tree thinks there has been a nuclear winter then that is ok. You might want to ensure you have good drainage as water and no sun is the start of algae and other such issues.
Early Autumn Leaf Fall
Heat stress, being potted, lack of water, being boxed up for a few days etc can cause early Autumn leaf fall. Once planted, normal service will resume next season.
Do I Need To Stake My Ornamental Tree?
9 out of 10 times the answer will be no, especially if under 200cm tall. However our article on Tree Staking should help guide you.
Climate Change has increased aesthetic foliage issues such as Powdery Mildew, Shothole, Rust, frost damage etc These are not terminal issues and will usually last a season or less. All trees are inspected before being sent out to ensure they are fundamentally healthy and will bounce back.
Planting In The Corner Of A Garden
Air and light is reduced in this location which could promote fungus and bacterial issues. If the corner is of the house and a fence then you also have leeching issues to contend with from cement and wood preservatives. Also when it rains, that area would experience higher water levels so we advise against it unless the plant is very hardy.
Mature Tree Warranty
Once a tree is over 3 years old, the failure rate is considerably less and our Tree Warranty does not cover it at 100%. Please check details.
Water Logged Conditions
Willow, Alder, Birch and Poplar may help lower the water level so long as you do not have permanent standing water e.g. your local diving and sailing club meets on your lawn.
