Zoysia:
In
1906 Dr. Frank N. Meyer, a noted plant explorer, collected seed
in Korea and introduced Zoysia into the United States (Meyer collected
the first Centipede grass seed in China ten years later).
Japonica Zoysia,
one of four distinctly different families of Zoysia, is also known
as Korean or Japanese Lawngrass.

A warm season, creeping
perennial, Zoysias form a dense turf by means of slow growing underground
rhizomes and above ground stolens (runners).
In
1951 Meyer Zoysiagrass, a Japonica selection made by Dr. Ian Forbes,
was released. Soon thereafter Dr. Forbes released Emerald Zoysia, a
fine textured hybrid similar to the better strains of Matrella Zoysia.
Meyer and Emerald have been popular for 40 years and many people consider
them the ultimate in lawn grasses.
Zoysia seed are
hand stripped and cleaned in the Orient and have been exported to the
U.S. and other countries for many years. Fifty
years ago Zoysia researchers were dreaming of and working at finding
a Zoysia which would produce a superior turf AND enough seed to justify
commercial harvest.
Hundreds of selections
were observed and evaluated at the USDA Research Station at Beltsville,
MD as well as at other public and private research centers. Plant explorers
continue to search for different and better Zoysias in Korea and China,
where it has grown "wild" for centuries.
The "Green
Revolution" has more than doubled the world's food supply in the
last half of the 20th century, largely through the efforts of plant
breeders who created high yielding "hybrids" by cross-pollinating
selected parent plants.
Zenith is the progeny
of three parent plants which have yellow-white flowers. Each parent
was selected for superior attributes such as leaf texture, color, disease
resistance, drought tolerance, fall color retention, uniform color when
dormant, and early spring greenup.
Zenith is in the
Japonica family, as is Meyer Zoysia, and is similar to Meyer in many
respects, including blade width and color. It is somewhat less dense,
thus making it easier to mow and providing a better opportunity for
interseeding with tall fescues for year-round color. Zenith grows well
in full sun or under light shade, and is presumed to have good cold
tolerance.
When compared with
turf produced by Japonica seed imported from the Orient, Zenith is far
superior in appearance with a finer blade, brighter color, better rust
resistance, much better fall color and earlier spring greenup.
