Propagation

'Italica' - The most common fastigiate form, but a very poor landscape plant that is short-lived and prone to disease. It grows quickly to 50' tall and perhaps 10' wide. The habit is strongly columnar and the branches are harshly upright.

'Lombardy Gold' - Similar to 'Italica', this plant has yellow-gold leaves.

'Majestic' - Marketed as an improved 'Italica', this pyramidal male form grows quickly and purportedly has less susceptibility to disease.

'Thevestina' (also known as 'Theves' and 'Afghanica') - A female clone marketed as being similar to 'Italica', this plant in fact grows more broadly and has whitish bark.
