To the botanist, the word fastigiate means
'with parallel, erect, clustered branches'. It has rrow
become more widely used in a more generalized sense
for trees with narrow crowns. All those mentioned are
derived from natural sports and do not come true from
seed (if that is produced). They are propagated as cultivars.
They generally need careful pruning when young to ensure
the necessary erect growth.
Their placing needs great care, as they
inevitably have an unnatural look. Fastigiate conifers
accord well when planted in the regular pattern of formal
gardens-the use of the true cypress in the great Italian
gardens of the Renaissance. Fastigiate trees can be
skilfully used, too, for adding a steadying vertical
element to a steeply sloping site. The planting of a
'pair one on either side of the introduction to a vista
can be very effective. Some of the less erect-growing
are excellent for planting in narrow roads, or, for
example, at the centre of a lawn where space is limited.
