Ginkgo biloba
Ginkgo or Maidenhair tree is a unique tree because there is only one species in the
genus, Ginkgo biloba. The leaves are also distinctive with generally two lobes that
are somewhat leathery, fan-shaped, and have almost parallel veins.
The species can reach 50 to 80 feet high and 30 to 40 feet wide after many years;
it grows very slowly. Ginkgo is not very picky of its growing conditions and is quite
tolerant of a wide range of soil conditions, which make it a great choice for urban
environments.
Leaves are bright green in summer turning a beautiful bright yellow in fall. Ginkgo
is dioecious (separate male and female trees). Select males whenever possible due
to the fleshy covered seed of the female, which can be messy and emit a noxious, foul
odor after falling to the ground. Many cultivars exist today including some new dwarf
cultivars, weeping forms, and variegated forms. A popular male cultivar is ‘Autumn
Gold’.
No serious insect or disease problems.
