Plant the bulbs about three inches deep in any good soil, upon the lawn or in beds, in clumps or chains. They need not be removed from the beds for years. If desired to dig them, do so after the foliage has turned yellow. Dry in the shade, clean and store in a dry, airy place until planting time. In lawns, the grass often chokes the bulbs in three or four years, and renewal is necessary.
Plant the bulbs two inches deep in ordinary garden soil in autumn. Allow the foliage to die naturally before digging for division, which should occur as soon as the plants show signs of deterioration. Useful for planting in lawns like snowdrops.
Usually propagated by cuttings of green or mature wood, often also by seeds sown in spring. The plants usually thrive in all moderately moist soils except the lightest and heaviest; some, however, demand dry ground, thus being useful for planting among rocks; others (a few) wet and peaty situations. As with soil the species and varieties stand all degrees of shade (except the deepest) and light, even to full sun. But there is such a large number of kinds that enumeration for specific situations is impossible here. Their season extends from early spring until late autumn, the former generally being profuse bloomers of only a few weeks' duration, the latter less floriferous but of extended season.
Plant the bulbs about six inches deep in rather heavy, dryish soil, well exposed to the sun. They may remain until they show signs of failing, when, after the tops have died down, they may be dug, divided and reset in a new place.
Sow seeds in a mild hotbed or greenhouse in early spring; transplant the seedlings when about two inches tall to small pots, and when the ground becomes warm to ordinary garden soil about twelve or eighteen inches apart. Later and successional sowings may be made in the open ground. For winter bloom seed may be sown succession ally, beginning in late summer. The plants grow readily from cuttings.
Sow seeds in early spring where the plants are to remain and thin to about eighteen inches apart. Any garden soil. Make successional sowings, For winter use sow successionally, commencing in late summer. If desired, may be started in a mild hotbed or greenhouse and transplanted to small pots when about two inches tall. When spring opens they may be set in the garden.
Annual sunflowers are raised from seed usually sown where the plants are to remain, the plants being allowed to stand from two to five feet apart according to species. The perennial species are generally divided after once having become established. They nearly all thrive best in a light, even sandy soil.
Sow seeds in rather poor soil where the plants are to remain; thin the small kinds to about six inches, the large ones to twelve inches,. In the north give a light mulch of litter or leaves during winter.

Plant the corms in any good garden loam, commencing when the ground becomes fairly warm and continuing at intervals of ten days or two weeks until about June 1st. The corms should be from five to ten inches apart and three inches below the surface. At the approach of cold weather, dig the corms, dry well, divide, and store like gladiolus corms in dry, airy quarters.
Treat like Montbretia, which see.
Plant the bulbs in mid or late spring, about one inch below the surface and about six inches apart in good, light loam. Only such bulbs as have not a woody piece of last year's stem or a brownish cavity in the center are of use for blossoming purposes. Before frost, dig, dry, clean and store the bulbs in an airy, frost-proof dark room. The offsets should be cut off at planting time and, if desired, planted by themselves. They may require two years to attain blossoming size. The old root should also be trimmed off at planting time.
Plant bulbs about four inches deep in autumn, and protect with light mulch during winter. When foliage turns yellow, dig, dry in a shady place, clean, and store in airy quarters until autumn. If desired, the bulbs may be left for two years.
Sow seed in midwinter or until early spring in the greenhouse or a hotbed; transplant when an inch or so tall to small pots and set in ordinary soil two feet apart as soon as danger of frost has passed. In good soil they need more room. Choose new situations each year. For the propagation of a particular variety or colour cuttings of sturdy shoots must be used, since seedlings are ratner unstable as to colour. Germination of the seeds is thought to be hastened by soaking in warm water over night.
See Ravenna Grass.
Sow seeds in the open ground where the plants are to remain and thin out to about eighteen inches. They may be started under glass if desired.
Propagate by means of offsets, seed, stem, ana rhizome cuttings. Plant in any good soil, sandy loam preferred. Set the plants about four feet apart in groups. They like sun and will do well among rocks.
Set plants under greenhouse benches, in hanging baskets, vases, etc. Readily propagated by means of layers or cuttings.
In autumn or during winter plant in pots of ordinary potting soil and plunge in a moist place under the greenhouse bench. The earlier planted specimens may be expected to bloom toward spring, if not allowed to become dry. Winter is, however, the resting season. When the weather becomes settled they may be transplanted to light, fairly rich soil. The bulbs may also be wintered in a rather moist place and planted in the spring. Long successions may be managed by combining these two methods. In the garden the plants should stand eight inches apart and the bulbs three inches deep. In autumn dig, divide the bulbs, and either plant or store.
Sow the seed in early spring in a hotbed; transplant when a couple of inches tall to flats or pots and set in the open after frost has passed. For later blossoms sow in the garden where the plants are to remain and thin out the excess to about two feet. Dwarf varieties may be set as close as five inches.
