Bulbs valuable for naturalization in woodland and wild garden areas must be of the kind which will continue to increase without further care than is ordinarily given to such an area. All of the material in this group, except the gold-banded lily, may be expected, after being properly planted, to continue with the succeeding years to become thicker in growth and still remain nearly as vigorous as when first planted.

Plate XLIII. Our garden steps can be made a part of the flower garden, and not the usual cold and uninviting mass of stone or brick, by a well-designed grouping of plants adapted for growth in the earth-crevices among the rocks. Note the use of candytuft, ground phlox, moss pinks, varieties of stonecrops and rock cress. (See page 208, group XXIX-F, also see group XV-C)
