Half Hardy Perennial.
Two to four feet.
Flowers purple, in several shades; also white.
In the greenhouse the “Cherry Pie”
is perennial; but out of doors it disappears at
the first real frost.
The best form of culture for the amateur gardener
is to buy small plants in pots at bedding-out
These should be put out in fairly rich soil in
an open position; they may be allowed to cover
the ground, or may be trained to some height on
a small trellis-work of sticks.
Cuttings may be made in autumn, to be kept under
glass during the winter.
