Alnus incana Laciniata is an ornamental, cut-leaved version of common alder with a pyramidal crown that suits wet, boggy grounds.
Following the growth of summer catkins, small green-brown cones develop around September and remain in place for most of winter, even after the yellow-toned autumn foliage has dropped.
It is a fast growing tree, reaching a potential height of 20 metres in 20-50 years depending on the soil conditions.
It thrives in moist, damp soil and will grow in exposed situations. Smaller than the common alder, suitable for mid-size gardens and perhaps a standalone specimen in a lawn. Pollution tolerant so useful for screening alongside a road or for overlooked situations.
