exposed to cold and cutting winds.


DEUTZIA.

DEUTZIA CRENATA (_syn D. scabra_ and _D. Fortunei_).--Japan 1863. This
is of stout, bushy growth, often reaching a height of 8 feet, and
lateral spread of nearly as much. The ovate-lanceolate leaves are rough
to the touch, and its slender, but wiry stems, are wreathed for a
considerable distance along with racemes of pure white flowers. It is a
very distinct shrub, of noble port, and when in full flower is
certainly one of the most ornamental of hardy shrubs. The
double-flowered form, D. crenata flore-pleno, is one of the prettiest
flowering shrubs in cultivation, the wealth of double flowers, not
white as in the species, but tinged with reddish-purple being highly
attractive. D. crenata, Pride of Rochester, is another form with
double-white flowers, and a most distinct and beautiful shrub. Two
other very beautiful varieties are those known as D. crenata Watererii
and D. crenata Wellsii.

D. GRACILIS is a somewhat tender shrub of fully 18 inches high, with
smooth leaves and pure-white flowers produced in the greatest freedom.
It does well in warm, sheltered sites, but is most frequently seen as a
greenhouse plant. A native of Japan.
