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.
