This is another garden flower that can be made to do excellent work in the house in winter if properly treated.
Look the old plants over, and select a shoot of small size that can be broken away from the parent plant in such a manner as to bring a piece of root with it. Pot this in soil taken from the garden where the old plants grew. It will be inclined to make a branchless growth if left to its own devices. Do not allow this. Nip off the top of it when it is a foot high, and thus force branches to develop. Ever after you take the plant into the house keep watch for the red spider, who seems to have an especial fondness for this plant. Shower it as often as possible, and give it a dip-bath once a week.
Along about holiday-time it ought to come into bloom. Its long spikes of scarlet flowers are as bright as fire, and they will rival the most brilliant Geranium on the list in making gay the window in which they grow.
This list would be incomplete if mention of a few of the best plants for hanging baskets were not made.
Saxifrage sarmentosa, often known as "Strawberry Geranium,"-though it does not have the remotest relationship with either of those plants-is a very pretty hanging plant. Its foliage is circular in shape, of a dark olive variegated with white. There will be a cluster of leaves, large and small; from these runners will be sent out; when they have grown to the length of a foot, another cluster of leaves will form. The habit of the plant is as pleasing as it is peculiar. Well-grown specimens will nearly cover the pot with foliage, and there will be runners festooning all sides of it with their leaf-clusters. Easily grown from runners which have been allowed to root by coming in contact with the soil.
