Iris pseudacorus grows from one and a half to three feet and blossoms in late May and late June. It forms luxuriant clumps, having many stems, which bear large broad-petaled flowers, yellow veined with brown. The leaves—long, stiff, and gray-green—are handsome. This is a beautiful plant for the margin of water, and is very pretty around a bird-bath. Propagate by division. This iris likes the sun.
The great purple Turkey flag will grow in either sun, or half-shade. The height is from two to four feet. The large fragrant flowers bloom in May, June, and July. This iris is very handsome in large groups and in the border. Propagate by division. It is a gross feeder, but grows well in any garden soil.

HAREBELL. This lovely jewel of the English woodland has drooping bell-shaped flowers, fragrant, and blue in color. The bells hang from tall stems. The leaves are long and grass-like. The height is from eight to twelve inches. It is bulbous. Propagate by offsets and give it occasionally a top dressing of manure. Scilla nutans blooms in May and June and prefers half-shade. There are varieties, white, pink, and purple.
HOLLY should be used for hedges and ornamental bushes. Some varieties grow very well in certain parts of the United States.
HONEYSUCKLE grows easily in any garden. It is a luxuriant creeper and is generous with its blossoms and lavish in fragrance. Use it for hedges and to climb over walls, arbors, trellises, gates and wire screens.
IVY. English ivy is a climbing and trailing evergreen sub-shrub, with beautiful large, dark-green leaves, richly veined, and of graceful heart-shape. The flowers are inconspicuous, but the berries, almost jet-black, are decorative. Propagate by half-ripe cuttings in rich, damp soil and protect in winter. Ivy prefers shade. It blossoms in June and July.
LADY'S-SMOCK (Cardamine pretensis) will grow in sun, or shade, but prefers a moist soil. Propagate by division. Its blossoms are pinkish lilac in terminal clusters and appear in June. The foliage is deeply cut. Lady's-smocks will grow in rock-gardens and are excellent border-plants.
LARK'S-HEELS. See Nasturtium.
LARKSPUR is a glorious flower, noble in masses of bloom and fine in growth, highly decorative, and lasts well besides. "Delphiniums are very easy to grow and can be planted at almost any time, but the best seasons are early autumn and spring when new growth commences. The great point is to plant them in rich well-dug and manured soil and strew coal-ashes about for the reason that slugs are very partial to these plants. Ample space must be left for full development as with age the roots increase greatly, so that two and a half feet apart is none too much. The plant needs a rather rich ground, for its growth is strong. Larkspur looks well planted in the back row of the mixed border."
