Calla Lilies
The Calla Lilies are plants belonging to the Zantedeschia genus
in the Araceae family. The genus contains seven plant species
and they are all commonly referred to as Calla Lillies. Some of
them have other common names as well. Zantedeschia aethiopica is
also known as giant white arum lily and common arum lily.
Zantedeschia albomaculata is sometimes sold as spotted arum
lily, and Zantedeschia rehmannii is known as the pink arum lily.
Zantedeschia elliottiana has a yellow shade and is therefore
called yellow or golden arum lily. The other three species,
Zantedeschia odorata, Zantedeschia jucunda and Zantedeschia
pentlandii, are usually called just Calla Lilies.
All the Calla Lilies originate from the African continent and
are found wild between north Malawi and South Africa. They are
often referred to as Arum Lilies. The Calla Lilies should not be
confused with the flowers found in the genus named Calla that
can be found in the Araceae family. This genus contains only one
species, the Calla palustris, and unlike the Calla Lilies, this
plant is native to cool regions in the temperate zoon and grows
wild in Europe, North America and northern Asia. Another source
of confusion regarding the Calla Lilies is that they actually do
not belong to the family of the lilies.
The Calla Lilies are all rhizomatous plants that can reach a
height of 1-2.5 meters. The leaves will grow up to 45
centimetres. The name Calla is derived from the Greek language
and means 'beautiful' and this is a very appropriate name since
the Calla Lilies are appreciated world wide for their exquisite
beauty. In regions too cold for these flowers, they are
cultivated indoors in homes and greenhouses. When you plant your
Calla Lily, it is important that the soil is free from salt
since Calla Lilies are very sensitive to salt. As long as you
provide your Calla Lily with appropriate soil, plenty of water
and lot of sunlight it is actually a though and durable plant
that grows fast. Use a nutritious soil that drains easily. Place
your Calla Lily in direct sunlight or light shade. Calla Lilies
will do best when the temperatures are kept over 70 degrees F.
An outdoor living Calla Lily will usually require no
fertilization as long as it has been planted in rich soil.
Indoor Calla Lilies, or outdoor Calla Lilies that are planted in
pots, should be given liquid plant food regularly. You can
either mix a very weak plant food solution and use every time
you water your Calla Lily, or mix a little stronger - but still
quite mild - solution and feed your plant every three weeks.
When the blossoming period is over, you should allow the foliage
of the plant to mature. Remove the flowers as the start to fade
and wither. Slowly decrease the amount of water until the leaves
have turned black. The tubers need at least 3 months to rest
before they can bloom again. Since the Calla Lily grows fast it
will eventually require repotting, and this is the ideal time to
do so.
