Type of FlowersLilium:
Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have "lily" in their common name but are not related to true lilies.
The botanic name Lilium is the Latin form and is a Linnaean name. The Latin name is derived from the Greek λείριον, leírion, generally assumed to refer to true, white lilies as exemplified by the Madonna lily.The word was borrowed from Coptic (dial. Fayyumic) hleri, from standard hreri, from Demotic hrry, from Egyptian hrṛt "flower". Meillet maintains that both the Egyptian and the Greek word are possible loans from an extinct, substratum language of the Eastern Mediterranean. The Greeks also used the word κρῖνον, krīnon, albeit for non-white lilies.
The term "lily" has in the past been applied to numerous flowering plants, often with only superficial resemblance to the true lily, including lotus, ranunculus, tulip, iris, anemone, agapanthus, zantedeschia, daylily, and others. All English translations of the Bible render the Hebrew shūshan, shōshan, shōshannā as "lily", but the "lily among the thorns" of Song of Solomon, for instance, may be the honeysuckle.
The range of lilies in the Old World extends across much of Europe, across most of Asia to Japan, south to India, and east to Indochina and the Philippines. In the New World they extend from southern Canada through much of the United States. They are commonly adapted to either woodland habitats, often montane, or sometimes to grassland habitats. A few can survive in marshland and epiphytes are known in tropical southeast Asia. In general they prefer moderately acidic or lime-free soils.
Many species are widely grown in the garden in temperate and sub-tropical regions. They may also be grown as potted plants. Numerous ornamental hybrids have been developed. They can be used in herbaceous borders, woodland and shrub plantings, and as patio plants. Some lilies, especially Lilium longiflorum, form important cut flower crops. These may be forced for particular markets; for instance, L. longiflorum for the Easter trade, when it may be called the Easter lily.
Lilies are usually planted as bulbs in the dormant season. They are best planted in a south-facing, slightly sloping aspect, in sun or part shade, at a depth 2½ times the height of the bulb (except L. candidum which should be planted at the surface). Lilies have contractile roots which pull the plant down to the correct depth, therefore it is better to plant them too shallowly than too deep. A soil pH of around 6.5 is generally safe. The soil should be well-drained, and plants must be kept watered during the growing season. Some plants have strong wiry stems, but those with heavy flower heads may need staking.
