Product details

Originating in southern Italy and introduced in 1820, this fast growing, medium tree has a conical habit.

It’s shiny green pear-like leaves last well into winter particularly under street lighting.

It produces notably larger fruits than other alders.

Good for parks and as a street tree and also recommended for coastal plantings.

It thrives on all ground including dry high ph soils but is most at home nearest water.

Being highly tolerant of urban pollution it is a particularly adaptable urban tree but must be given enough room or it can outstay its welcome. Italian trials indicate that it can even tolerate acid rain.

Bark is a glistening brown when young but matures to be rougher.

Once heralded by many as the perfect candidate for an urban tree, its vigour can cause the lifting of hard areas over time so I would advise planting on verges rather than paved streets where it can outplay its welcome.

Mature height: 12-17m

Mature spread: 8-12m
