The botanic
name Lilium is
the Latin form and is a Linnaean name. Lilium 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. Lilies
are tall perennials ranging in height from 2–6 ft (60–180 cm). They
form naked or tunic less scaly underground bulbs which are their overwintering organs. In
some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found.
Some species develop stoles. Most bulbs are deeply buried, but a few
species form bulbs near the soil surface. Many species form stem-roots. With
these, the bulb grows naturally at some depth in the soil, and each year the
new stem puts out adventitious roots above
the bulb as it emerges from the soil. These roots are in addition to the basal
roots that develop at the base of the bulb. Naturally most cool
temperate species are deciduous and dormant in winter in their native environment. But a
few species which distribute in hot summer and mild winter area lose leaves and remain relatively short
dormant in Summer or Autumn, sprout from Autumn to winter, forming dwarf stem
bearing a basal rosette of leaves until accept enough chilling requirement, the
stem begins to elongate while warming. The flowers are large, often fragrant, and come in a range
of colours including whites, yellows, oranges, pinks, reds and purples.
Markings include spots and brush strokes. The plants are late spring- or
summer-flowering. Flowers are borne in racemes or umbels at the tip of the stem, with six petals spreading or reflexed, to give flowers
varying from funnel shape to a "Turk's cap". The tepals are free from
each other, and bear a nectar at the base of each flower. The ovary
is 'superior', borne above the point of attachment of the anthers. The fruit is a three-celled capsule. Seeds ripen in late summer. They exhibit
varying and sometimes complex germination patterns, many adapted to cool
temperate climates.
