Lilies
Lilies belong to the Genus Lilium and are considered true
bulbs.
The bulb consists of modified leaves that are called scales. The scales
are attached to a flattened area called the basal plate. Also connected to the
basal plate is the roots of the plant. Some lily roots are contractile, which
means they have the ability to contract and pull the bulb down to it's optimum
depth. Most lily bulbs come in either white or yellow. They also vary in size
depending upon the species or variety of Lily. Lily bulbs come in a number of
different forms. Concentric bulbs is the most common form. Majority of the
garden Lilies are in this form. Concentric Lilies consist of a rounded pyramidal
basal plate surrounded by overlapping scales or various size and number
depending upon the variety. Another type of bulb is called Stoloniferous. These
look similar to concentric bulbs but send out one or more stolons from close to
the basal plate. These stolons end in a new bulb. The connective tissue will
eventually wither away and the new bulb will develop on its own. The other two
forms are Rhizomatous and Sub-rhizomatous are mostly found in a few North
American species.
Most
lily bulbs produce very thick, fleshy roots that have the ability to contract
and pull the bulb down to the depth of soil that is most optimum for its
survival. Bulbils also have this very same ability. When they fall to the ground
they will set roots and pull themselves deeper into the soil. Some lilies also
produce roots along the stem between the top of the bulb and the soil surface.
These work to help anchor and feed the bulb.
The stems of lilies are upright and are of various lengths
depending upon the species, variety, age and health of the bulb. Most are strong
but some are thin and wiry. Stem length come on the very tiny not more than a
couple of inches to towering giants over 6 feet. They also come in various
colours most being green but some being very dark to almost black.
The leaves of lilies come in various forms and most are long, pointed and
arranged around the stem in a spiral pattern. Some species have all the leaves
in a whorl pattern at various heights along the stem. The leaves of Asiatics are
narrower and more numerous than those of Orientals, which are broader and fewer.
Most lily leaves are protrude from the stem more or less in a horizontal fashion
but some hold their leaves upright along the stem. The actual leaf comes in
various shapes, some being long and narrow, others being wider and more
spatulate in shape. Leaf colour also varies between species and varieties.
Of course the real prize of the lily is the flowers. They all have the same
basic form which is composed of three outer petals called Sepals and three inner
petals. The exterior
colour of the three sepals may be a different than the interior colour. A good
example of this is L. Regale, which has a maroon bud but white interior
petals and sepals. The interior colours can be plain, spotted, splashed or
lines. The majority of lilies come in white, cream, yellow, orange and reds.
Blue does not occur naturally in lilies. Also occurring are pinks, mauves,
peach, maroon, purples and some greens. Petals can be smooth, but many have
ridges or raised points called Papillae. There are normally 6 anthers
that may or may not be fertile and one a single often three lobed stigma that
can be quite substantial.
