The stove and gi-eenhouse species will grow well
in any common soil; and may be readily increased
by ripened cuttings planted in sand, under a glass;
the stove species must be placed in heat. The
hardy kinds are rather ornamental and well fitted
for shrubberies ; some are propagated by cuttings
of the roots, and others by cuttings and layers.
The juice of R. radicans and Tojcicodendron is milky,
stains black, and is extremely poisonous. R. Coriaria
