Verbena venosa is a good old favorite. It is not hardy here, but winters well in a cold frame. It bears seeds abundantly, but old plants come into bloom several weeks before the seedlings; hence the desirability of keeping over a lot of them. This Verbena has deep purple flowers, blooms all summer long, is excellent for common bouquet work, a good grower and is not subject to blight or rust. In England, planted among Bijou pelargoniums, we find it in almost all large gardens.
If you want a floral display in summer, plant Petunias, and if you want a gay window in winter, the Petunia has no equal.
In a garden on Main Street a large variegated Century Plant is set on a pedestal four feet high. Virginia Creeper has grown around the pedestal, up over and hidden the pot, and some of the branches have twined through among the leaves of the century plant. The whole thing looks cosy and becoming, and the vines, by a little annual cutting, can be made to perform the same office for years unlimited.
Another case is that of an old Pear tree forked about six feet from the ground. The stem is clad in Virginia Creeper, and in the fork rests a pot full of Oxalis floribunda. The bunch of red Oxalis flowers sticking out from among the deep green leaves of the creeper has a novel and pleasing effect.
Plumbago Larpentse is at its gayest in September. Its deep blue flowers are very pretty. It is not hardy here in the open ground, but winters well in a cold frame. It is hardy from New York southwards.
Plumbago Capensis is, at present, our most copious and beautiful lavender colored flower. Cuttings struck last spring and transplanted from three-inch pots in May, are making this display. It requires greenhouse protection in winter.
Aponogeton distachyon or Cape Pond Weed has blossomed all summer long in our pond. Plants left out all winter are vastly stronger than those wintered in the greenhouse. It is hardy, providing the roots are deep enough to be beyond the reach of ice. Being a small plant it does not do so well in water over three feet deep as where it is more shallow.
