American frigetree |
Shortly after the majesty of the dogwoods
fade, another flowering tree blossoms forth seemingly from nowhere. The American fringetree (Chionanthus
virginicus), also known as white fringetree, grancy graybeard or old man’s
beard, puts out its floral display of masses of white fringe-like flowers after
the plant's leaves are about a third grown.
The flowers have individual elongated or strap-like petals up to an inch
long. The abundance of flowers can be
so great that the entire plant can be covered with blooms. An added attraction is that the flowers are
fragrant.
Plants generally produce only male or female
flowers though some flowers may be bisexual.
Male flowers are the largest. The
female plants produce dark blue fruits shaped like an olive and can be over an
inch long and are borne in large clusters.
(The American fringetree is a member of the Olive Family.)
The leaves of the fringetree are large,
egg-shaped and over 2 1/2" wide and up to 3-8" long. The tree is deciduous but the leaves can have
a nice yellow color in the fall.
This small tree is native from Ohio to over
much of the southeastern United States.
Mature trees can reach heights of 20 to 30 feet. The tallest tree now
known currently is in Texas and is 28 feet tall. The fringe tree is
easy to grow. While it prefers full sun,
it tolerates full shade too. It also
prefers a well-drained soil with a slightly acidic pH, but it can adapt to just
about any soil type. Pests and diseases
rarely bother this tree.
The fringetree has found its way into folk
medicine. Preparations made from the bark
have been used in the treatment of fevers and as a diuretic. A tincture made from
the bark and grain alcohol was used for jaundice. Native Americans used tea made from boiled
bark as a topical treatment for skin irritations, cuts and infections.
Finding these trees to put in your landscape
can be difficult. Production of
container-grown trees is fraught with problems.
Rooting of cuttings is nearly impossible. Germination of seeds is difficult due to a
double dormancy requiring a warm after-ripening followed by cold
stratification. Freezing the seed
following the after-ripening period might increase the germination rate. Some nurserymen report poor growth the first
year after establishing the seedlings in a container.
There has been some success in propagating plants by
mounding soil (mound layering) around young multi-stem plants in the spring. That winter the mounded plants are
divided. This is a slow way to propagate
but it can work.
