In Kendal. a mingle of alder and hazel grows in a sliver of river bank beside the walkway. Hardly trees, there's little soil for them to grow to maturity but a couple of days of perfect light when catkins are at their best gives a rare opportunity to study them close-up. All the image lacks is siskin, redpoll and goldfinch feeding on seeds as last-summer's cones burst open.
Catkins show well because they flower before Alder comes into leaf. Discrete twigs bear leaf-buds, last year's cones and new tree-flowers.
The variety is Alnus glutinosa, a welcome weed in our forest. It seeds everywhere, stabilises pond and river banks and burns well. (image of a cosy fireside.) In good damp soil it makes huge trees. What really surprises me is the growth rate of alder- metres per year if they like the situation- they grow as quickly as our sequoias and sempervirens although they won't last the thousands of years that the conifers will, barring accidents.
