Has large, showy, orchid-like flowers. Intermediate tolerance to
deicing salts. May be best as a park tree because of its messy
fruit. Has limitations due to cold hardiness. Use should be
restricted to the southern or western portion of the Northern
Tallgrass Prairie subsection if at all.

'Macho' is a male selection with ascending branches without
fruit and subsequent volunteer seedlings. Requires frequent
pruning when young to remove branches with included bark.
Restrict use to the southern and western portions of the
Northern Tallgrass Prairie subsection because of cold hardiness.

Winter hardiness and susceptibility to Eutypella canker limit
the usefulness of this species and its cultivars in the area
covered by this publication.
Maples other than Norway maple are sensitive to deicing salt.
Maples perform better in lawn or park settings and in groups,
rather than as single specimens in fully exposed boulevards.
Planting with the root collar at ground line is important to see
and treat girdling root syndrome.

Lombardy poplar is an upright, fast-growing cultivar that is
often used in windbreak and shelterbelt plantings. It is
extremely susceptible to several canker diseases and as a
consequence is short lived.
All poplars have shallow and aggressive roots. Do not plant near
pavement where shallow roots can cause damage.
