Ipomoea

These beautiful climbing plants are very suitable forcovering trellis-work, or for the pillars or rafters of the
stove-house. The seed is generally sown in April on a hotbed or under
glass, and the young plants set out in the border of the house in May
in light, rich soil. Success is mainly secured by allowing plenty of
root-room. The perennial kinds are increased from cuttings taken from
the small side-shoots placed in sand in a brisk bottom-heat. If grown
in the open they often shed their seed, and come up year after year
with but little attention. They make a good contrast to Canariensis.
The Ipomoea Horsfalliae, with its bright scarlet flowers, has a
lovely appearance, but must be treated as a stove evergreen. This is
propagated by layers, or by grafting on some strong-growing kind. It
thrives in loam and peat mixed with a little dung, and flowers in July
or August. Height, 6 ft. to 10 ft.
