If you are going to be a really-truly gardener, you will want to know something about the plants and flowers that you try to grow, so let's have a few words right here about the difference between the bulb and tuber families. They can be classed together because they both spring from what is in fact a storehouse filled one season with food to help them through the next season's bloom!

Hyacinths and daffodils, for example, come from BULBS, which are built up, layer on layer, exactly like an onion.

Dahlias and Cannas, however, grow from a TUBER, which is an underground knob on the stem, quite a little like a sweet potato, and which sends out the shoots that make new plants.

The crocus and the gladiolus both spring from a CORM, which differs from the bulb in that it is solid (not in layers), and from the tuber in that it is not like a potato in shape but oval.

The iris, though, grows from a RHIZOME, a thickened root running along the ground (often half exposed), which throws up the new plants as it spreads.

The bulb and tuber families are treated very much alike. Some of each are left in the ground year after year, like the daffodils and the lilies, while others, like the cannas and dahlias, have to be dug up, allowed to dry a little in the open air, and then stored in a cool, dark place for the winter. The rhizomes do not have to be "lifted," but are increased generally by root division,—cutting off a piece of the root soon after flowering, and planting where it will get a good start before next season's time to bloom.

Some people today would follow Mohammed's advice: "He that hath two cakes of bread, let him sell one of them—for bread is only food for the body, but the narcissus is food for the soul;" but few individuals—let alone a nation—would grow so wildly enthusiastic as once did the Dutch, as to spend every last possession to buy tulips! But we dearly love all of these groups, and are using them in increasing numbers every season. The fascinating work of growing certain kinds indoors during the winter I tell you about in the chapter on "The Care of House Plants," so here we will consider the outdoor culture.

The delicate snowdrop is the very earliest of these visitors, and planted in groups in half-shady places,—like under trees,—where they will not be disturbed, will thereafter take care of themselves. Then quickly follow the lovely crocuses, white, yellow, lavender, purple, and the varigated, which often are planted right where they fall after being scattered broadcast over the lawn,—though if the head of the house cuts the grass before the middle of April they should be set in a bed where they will not be touched.

Hyacinths are beautiful, but personally I do not care much about them in the garden, as they generally have to be planted in masses to get any effect, and need, therefore, to be used in large numbers, are more expensive than the other bulbs, and should be taken out of the ground soon after blooming and stored in a cool place until fall. However, one enthusiast that I know plants in rings of 6, and leaves them in the ground!

The daffodil, jonquil and narcissus are three types of the narcissus family, the daffodils usually being distinguished by their long trumpets, while the jonquils and narcissi have the little cup-like centers, and, moreover, are fragrant. They should be planted in the late fall, 4 in. below the surface, in soil that has been enriched 8 in. below the bulb. They increase rapidly, and do not have to be taken up, or even divided for years. If set in a border where their room is needed after they bloom, simply turn the tops down under the soil, and sow over them any low-growing annual, such as candytuft or poppies. My friend of the tiny "handkerchief" garden described in Chapter II, has—think of it!—over 1500 of these various spring-flowering bulbs in her border that are treated this way, and never taken up! Yet a few weeks after they have bloomed, the space they occupied is filled with new beauties.

Tulips—but as I told you, they once drove a whole country mad! Today we have probably far more beautiful ones,—and many can be bought in the fall at planting time, for $1.00 per hundred! Some bloom early, some late; some are short, some tall; some are cheap, some expensive. They will grow in partial shade or sun, and can be planted in groups in the border, or in marginal rows for edging. By carefully choosing from both the early and late varieties, you can enjoy your tulips for nearly two months; and by as carefully choosing your colors, have all sorts of artistic combinations. They should be planted 3 or 4 in. deep if the soil is heavy, and an inch deeper in soil that is light, and set 6 in. apart. They will prove a joy to your heart.

Tuberous-rooted begonias supply a much-felt want for lovely flowers in half-shady or shady places. If the bulbs are started in the house in sand in February, they will be in full leaf when ready to set out in May, and will bloom from June until frost. Don't, please don't, plant them upside down, but be sure that the rounded part rests on the soil. They require light, rich earth, with plenty of water, given after sundown.

Cannas only too often are planted in big, showy beds where they break our rule of "open lawn centers." In fact, they are a little hard to place, but look well in a corner, in beds along a drive, or outlining a boundary. The ground should be spaded 2 ft. deep, well fertilized, and then kept watered. Set plants 2 ft. apart.

The iris is one of the most beautiful and most satisfactory of all the hardy plants. It grows in almost any soil, and any situation, but does best in rich ground, with plenty of water. It may be planted either in early spring or after August. The dwarf varieties, from 6 to 18 in. high, bloom during March, April and May; the German iris, standing often 3 ft. high, in May; and the marvelous Japanese kinds, sometimes 4 ft., with blossoms 8 to 10 in. across, closing the season in July! (In heavy soil they are not so tall.) When used alone in beds, one prominent grower suggests that the German iris be combined with hardy asters (set in between), and the Japanese with gladioli, to keep a succession of bloom until late fall.

Lilies for the garden are of many varieties, requiring different kinds of treatment. As a general rule, however, when the soil is heavy, set your bulb in a nice little nest of sand, and give a blanket of the same before filling in with the ordinary earth.

Lilies-of-the-valley will grow almost anywhere, but do well in a half-shady position. They should be planted in masses, and fertilized in September. When too thick, they can be transplanted in the early spring. They increase rapidly.

The gladiolus (accent on the i, please,) can get along in almost any kind of soil,—though it does best in rich,—if only it is planted in the sunshine. The ground should be well dug up and fertilized beforehand and around New York the corms set as early as April. Then, for succession of bloom, plant at least every 10 days up to July 1st. After they are well started, fertilize with (preferably) sheep manure, dug in around the roots, every two weeks. Cultivate often, and keep well watered. Plant gladioli at least 4 in. apart, and 4 in. deep, and tie up for protection to 4-ft. stakes. Lift your bulbs,—corms, I should have said,—late in the fall, let them dry in the air a few days, and then store in a cool, dark place, free from frost.

Narcissi are described with the daffodils.

Peonies are classed with the Perennials, in Chapter III. Their tuberous roots are best divided and set out in September. They can be left undisturbed for five or six years.

Tuberoses can now be procured which will bloom from May until frost. They are easily grown, with no particular care, and take up very little room. Stake for safety from storms.

The dahlia next,—saved until the last for all the space I could possibly give it! And so popular is this flower today, that some growers raise nothing else!! One man offers us over 700 named varieties!!! Moreover, a great big club, known as The American Dahlia Society, has been formed by people who are interested in—and wish to help along—the growing of dahlias.

And it's no wonder that they are popular, for no other flower can be grown in the garden that will give as many, as large, as vari-colored and as beautiful flowers as the dahlias. Coming in every shade but true blue, and ranging from the tiny button pom-pon to the largest prim show or the formal decorative,—from the unique collarette to the ragged pÆony-flowered, the amateur gardener can hardly believe that they really all belong to one family!

Of such easy culture, too. Anybody can grow them! Any good, well-drained garden soil will do, but must have manure spaded in 10 in. deep and the tubers must be planted in the sun. The poorer the ground, though, the more fertilizer will you have to use. Heavy soil should be dug up and mixed with ashes to make it light. Plant the tubers lengthwise—not up and down!—in a drill at least 6 in. deep, and not less than 2½ ft. apart.

For early flowering, put in your bulbs as soon as all danger of frost is past, but do not set near trees or shrubs that would take their nourishment. When they sprout, pull up all shoots but one or two, in order to produce the finest flowers. Keep the ground well cultivated, but do not water until after the buds have formed, otherwise you will have principally stalks and leaves. But once the buds do show, water frequently in order to enrich the color, and dig in fertilizer around the roots several times during the flowering season, to produce fine, big blossoms.

Tie each plant to a 5-ft. stake, to protect from the wind, but in driving be careful not to pierce—and ruin—your tuber. Nip off all the buds that are imperfect or weak, and cut your flowers with their attendant buds and foliage. They will look better, and no further disbudding of the plants will be necessary. And the more you cut, the better your dahlias will bloom!

Soon after frost has killed the leaves, carefully dig up the tubers with a spading fork. You will be surprised to find often half-a-dozen where you set but one! Allow them to dry in the air for a day or two, then put away in a cool, dark cellar, with a bag or paper thrown over them, and leave for the winter. In the spring when ready to plant again, cut each tuber so it will have a little bit of the heart of the clump on its end, as it is close to this that the new shoots start.

Growing dahlias from seed is a most fascinating pastime, for there is no telling what you may get! The child is rarely, if ever, like its mother,—and this is the only way that we get the new varieties. YOU might happen to grow one of the finest yet! The seed is started early indoors, and very easily grown. Certainly it is worth trying.
