Rose of Sharon will help bring a bit of tropical beauty
to more temperate climates. The big blooms that arrive
later in the summer will help revive your garden after
the flurry of spring flowers have faded. A true Zone 5.
Can be grown in zone 4b areas of Colorado but need
maximum protection and heavy mulch- much like Tea Roses.
Expect this plant to be more shrub formed than tree like
in Colorado growing 6-8ft tall and wide.
It is best to grow Rose of Sharon in full sun, though it
can tolerate up to part shade. Don't be surprised if the
leaves arrive after most of your other plants, as they
start producing the leaves late in spring. Leaves are
2-4" long, often with 3 lobes, and jagged edges.The
flowers are 2-5" wide, in shades of white, pink, red,
blue, purple, and violet. There is often a different
spot of color in the middle of the throat.
is said that Rose of Sharon can be VERY invasive due to
the numerous seeds produced in the capsules. This is
really only a problem in more southern and humid
locations. The blossoms are edible.
Be careful when using this as a specimen plant - remember that the
leaves appear late in spring and the blooms do not show
until later in summer. Better for use in a border with
other plants.This is an excellent plant for attracting
Although, Rose of Sharon grows best in moist, well
drained soil that contains lots of organic matter, it is
able to tolerate a wide variety of soils and is somewhat
tolerant of drought conditions. Its the extreme cold
winters to watch for. In the cooler zones (where the
temperatures fall below -10F in winter), be sure to
mulch around the plant well during the winter season.
If you have hot summers, you are in luck - Rose of
Sharon actually prefers the heat, and will bloom
better.Though it is naturally a multi-stemmed shrub,
Rose of Sharon can be trained to have a single trunk,
looking more like a tree. It can also be trained as an
espalier or shaped into a hedge.
Prune as needed to maintain the shape desired. In
winter or early spring, last season's growth should be
pruned away, which will help produce bigger blooms.
The buds may drop if the plant is watered too much or
too little, or if too much fertilizer is applied.
