MAKING A GARDEN OF PERENNIALS

THE HOUSE & GARDEN "MAKING" BOOKS

It is the intention of the publishers to make this series of little volumes, of which Making a Garden of Perennials is one, a complete library of authoritative and well illustrated handbooks dealing with the activities of the home-maker and amateur gardener. Text, pictures and diagrams will, in each respective book, aim to make perfectly clear the possibility of having, and the means of having, some of the more important features of a modern country or suburban home. Among the titles already issued or planned for early publication are the following: Making a Rose Garden; Making a Lawn; Making a Tennis Court; Making a Fireplace; Making Paths and Driveways; Making a Rock Garden; Making a Garden with Hotbed and Coldframe; Making Built-in Bookcases, Shelves and Seats; Making a Garden to Bloom This Year; Making a Water Garden; Making a Poultry House; Making the Grounds Attractive with Shrubbery; Making a Naturalized Bulb Garden; with others to be announced later.

MAKING A GARDEN OF PERENNIALS

INTRODUCTION

The successful garden has a permanent basis. There must be some flowers that appear year after year, whose position is fixed and whose appearance can be counted on. The group classed as perennials occupies this position and about flowers of this class is arranged all the various array of annuals and bulbs. These last act as reinforcements in rounding out the garden scheme.

Perennials are plants that live on year after year if the conditions surrounding them are congenial.

Trees and shrubs are perennials, of course; in these the stems are woody, but we are considering only those known as herbaceous perennials, having stems of a more or less soft texture that, with the exception of a few evergreen species, die back each fall, new ones appearing the following spring.

Quite a number of them are too tender to be generally grown as hardy perennials, but those that bloom freely the first year--like the snapdragon--are treated as annuals, discarding them when the season is ended.

Some biennials--those that do not bloom until the second year, and then die--may be placed among the perennials and considered of their class, because they seed so freely at the base of the parent plant and bloom the following year, that their presence in the border is nearly always assured. The only thing necessary to do is to transplant those not in the situation you desire them to bloom in. Rudbeckia triloba, one of the Black-eyed Susan type, is not only a good example of this class, but a charming plant that all should grow, and, moreover, it is a very accommodating one, doing splendidly in semi-shady places, such as north of buildings or under weeping trees like the rose-flowered Japanese weeping cherry. It is at home in full sunshine where it will form a broadly rounded, bushy plant about three feet in diameter and, when in full bloom, with its myriad of black-eyed flowers, it can dispel the worst case of melancholia a dyspeptic ever enjoyed. It requires a good open, rather light soil to do itself justice. If lifted when in full bloom, put into a ten-inch pot, well soaked at the roots, and set aside for a few hours away from sun and wind, it will last for two weeks as a porch or house plant.

We hear a good deal about the gardens of our grandmothers, perennial gardens, in which the plants outlived the flagstones at the house door.

With a few exceptions, perennials are not long-lived. The gas plant, peonies, some of the iris, day lilies, and a few others, seem permanent.

The usual run require to be taken up about every two or three years and divided. There are two reasons for this. In the first place, the roots have exhausted all the food within reach and, again, the main crown, from which spring the blooming shoots, dies from exhaustion. At the outer edge of this decay is generally a fringe of "live matter" which, if taken up, separate from the decayed center, divided, and reset in good soil, will rejuvenate itself, and soon form a new plant.

In unfavorable sections the Texas gaillardia will lose its crown during winter, and the anxious novice watches impatiently in the spring for its reappearance, and finally digs it up only to find that while the crown is decayed the roots are alive, and here and there, on these, new plant buds are forming which, if not disturbed, would soon make good plants, probably not placed, however, just where wanted. Nurserymen often avail themselves of this peculiarity and increase their stock by taking up a plant, cutting the roots into small sections, and growing them separately.

We must remember that nine-tenths of the plants we grow are exotic--natives of distant parts and climes--coming from various atmospheric conditions, and from all kinds of soil. We bring them into our garden and grow them all under one climatic influence and in the one kind of soil we happen to possess. Certainly we cannot expect uniform success with all of them. You might as well bring into one room unlettered natives of distant climes and expect them all to enter into a general conversation. Even in gardens quite near each other, their permanence varies. I cannot grow, successfully, any of the boltonias, while within a quarter of a mile of me, in a friend's garden, they grow like weeds. Our soil is the same, and one would suppose that the climatic conditions were, still the fact remains. I merely mention this so that any novice finding that he cannot grow some plants as well as others near him, may not feel lonesome in his grief. It is, however, a good plan, when a plant supposedly easy to grow, fails to materialize, to try it in another part of your own garden, and if it does not do well there, discard and forget it--the world is full of good things.

Due to the fact of the perennial's habit of annual recurrence the cultural directions are different from the flowers of but a season's bloom. There are some vital fundamentals that every gardener should know and some short cuts to success that every one may know. Since perennials, then, form the very kernel of the garden these are things of first importance in the growing of flowers and will be here elaborated sufficiently to give the reader an impetus that will carry him at a bound into the inner circle of the garden mysteries.

PREPARING THE BEDS

Do we want a successful flower bed--one that our neighbors will envy--or one in which the plants are struggling to exist? If we want the former--and who does not?--we must give our plants good pasturage. They are as fond of the fat of the land as we are, and, since they gladden our hearts with their radiant blooms, we should treat them fairly. And how? By giving them a good, deep soil for their root-run, not only rich in food, but loose and friable.

Most all virgin soils contain ample plant food, but the deeper part lacks the result of the action of air, sun and frost, and the natural humus of decayed leaves and grasses. The plant food it contains is "uncooked"--that is, not ready for plant assimilation. Therefore, the beds to contain your perennials should be dug at least two feet deep--three is better--and good garden soil, or soil from a corn-field or any hoed crop where the weeds have been kept down, used to supplement all but the top layer one foot in depth. All of this applies to tree and shrub holes also. This top layer of one foot in depth is apt to be in fair condition for immediate use and may be applied in the bottom of the bed, mixed with either fresh or rotted manure. The soil brought in may be mixed with old manure and placed on top.

A word about "old manure" is opportune here. Any manure that has been piled up for a year or more in a weed-infested corner and used on your grounds, especially on your lawn, is the best promoter of exercise I know of, and can keep you busy all summer dislodging the weeds that spring from the seed its bosom protected.
