Perennial Flower Information
Hibiscus – Marsh Mallow, Swamp Rose
Mallow, Mallow Marvels
perennial Mallows bear some of the largest flowers of
any of our perennials and present a gorgeous sight when
in bloom. They grow from 3 feet to 8 feet tall and the
branches spread out over a great area. The leaves
are large and grayish green in color. The flowers resemble
a single Hollyhock bloom, only they are much larger,
some measuring from 6 inches to 10 inches or 12 inches
across. The colors range from white with crimson centers
to deep crimson, but most of the colors are soft, causing
them to blend with other flowering plants. The plants
begin blooming in July, but are at their best during
August and September. Altogether these large Mallows
present quite a tropical aspect to any planting- The
Swamp Rose Mallow (Hibiscus Moscheutos) grows
4 feet or 5 feet high, and has flowers 6 inches across
of a clear rose color with a large dark eye in the center.
This is a very showy plant. The Crimson-eye Rose Mallow
(H. oculiroseus) has large, pure white flowers with
a deep crimson eye. The flowers are extremely large
and appear velvety.’ The Mallow Marvels comprise a group
of especially large flowering sorts.
Mallows are hardy and adapt themselves readily to almost
any planting. When grouped in masses the large plants
present an extraordinary picture. They may be planted
either among shrubs or used as a substitute for them.
The plants are too large for the ordinary garden border
because they require much room, but they can be used
in large beds of mixed flowers.
Mallows prefer a moist soil although they will do equally
well in dry soil, sun or partial shade The plants die
down to the ground during Winter and are about the last
plants to show green shoots in the Spring They grow
very rapidly and do not require much care. A light mulching
of the plants is good for Winter.
They are propagated from seed which will produce blooms
the first year if the seeds are sown early enough. The
roots are easily divided and one can always be sure
that the plants will come true to form if this method
