If you have a record like this of every lily, you possess a most valuable book on the culture of lilies; and, as we said at first, the cultivation of these plants is little understood. A thoroughly authentic, practical record will help you more to become proficient in the art of lily-growing than any amount of impracticable theory. Now some words to those who are growing lilies in pots. As we have seen, most species grow well in pots. All do well except the following, which are unsuitable for pot culture. The reason why they are suitable is also given. _L. Cordifolium_ (too straggling). All the _Isolirions_, because they are not sufficiently ornamental for pot culture. _L. Humboldti._ This lily does not do well in pots; why we do not know. _L. Martagon_, _L. Pomponium_, _L. Pyrenaicum_, _L. Chalcedonicum_, _L. Monodelphum_, _L. Testaceum_. The last six lilies are unsuitable for pot culture because they require to become established before they will condescend to flower. Most lilies grown in pots can be kept in the open air or in a room, or anywhere you please, but the following require protection of some sort:— Half-hardy species. These should not be put out in frosty weather; otherwise they may be grown out of doors. If you have planted them in the ground at a sufficient depth, they will stand all but a very severe winter. _L. Giganteum_, _L. Cordifolium_, _L. Formosanum_, _L. Wallichianum_, _L. Washingtonianum_, _L. Catesbæi_, _L. Polyphyllum_, _L. Roseum_, _L. Hookeri_, _L. Oxypetalum_, _L. Alexandræ_. The following usually need a greenhouse to grow them well:—_L. Philippinense_, _L. Neilgherrense_, _L. Nepaulense_, _L. Lowi_. Would you like to have lilies in pots in your room? You can have them even if you do not possess a greenhouse. You can grow the lilies in the ground and transfer them to pots just before they begin to flower. For this purpose plant the bulbs in the open ground in rather lighter soil than you would if the lilies were to flower in the open. Place the bulbs about four inches deep. You need not remove the plant until the flower-buds are nearly fully developed. Then take up the lily with the surrounding earth, place it in a big pot, drench it with water, and leave it in a cool, shady place for three days. Then give it a good dose of liquid manure. You may then take it into your room, and it will flower as though nothing had troubled the tranquillity of its existence. Not all lilies are suitable for this treatment; only those species which will grow in light soils should be used for this purpose. _L. Longiflorum_, _L. Auratum_, _L. Speciosum_, and _L. Rubellum_ are most suitable for this form of culture. About the beginning of November all your lilies in pots will have flowered and died down. What are you to do with them now? Shake the bulbs out of the pots; examine them; remove any off-shoots; do _not_ cut off the roots; wash them in lime-water and re-pot without delay.
