HIBISCUS SYRIACUS (_syn Althaea frutex_).--Syrian Mallow. Syria, 1596.
An old occupant of our gardens, and one that cannot be too freely
cultivated. When favourably situated, it often reaches 6 feet in height,
with three-lobed, neatly-toothed leaves, and with large, showy blossoms
that are borne towards the end of summer. The typical species has
purplish flowers, with a crimson spot at the base of each petal, but
others, varying in colour from snow-white to purple and blue, are common
in cultivation. H. syriacus coelestis bears bright blue flowers, while
H. syriacus variegatus has beautifully variegated foliage. Of the
double-flowered forms, there are several beautiful and worthy plants,
the following list containing some of the best varieties of this popular
H. syriacus albo-pleno.
