African Violets our first indoor flowering plant |
Today's African violet was discovered in 1892 growing in two separate locations in northeast Tanga in eastern
Africa by Baron Walter von Saint Paul. Baron a horticulturist was the governor of German East Africa and fell
in love with this plant. He sent seeds and rooted laves to his father in Germany where they were grown and
quickly became very popular with the Horticultural circles. Herman Wendlan, a prominent botanist at the
Royal Botanical Gardens in Herrenhausen, Germany, gave the genus name Saintpaulia in honor of its discovery
and the two species became the parent of most of the cultivators available today.
The African violet became very popular because of its ability to thrive under normal conditions found in most
homes and it became a great specimen plant for centerpieces, and did very well in dish gardens too.
The African violet was introduced to the United States gardener in 1894 and hundreds of cultivars have
been developed that provide a wide range of flower colors, flower types, foliage types, and plant sizes from
miniature's to very large hybrids. The African violet became one of the first indoor flowering plants and are
still today one of the top selling small potted flowering plants for any season that blooms all year on any window
sill or plant table. In 1995 African violets sales exceeded 25 million dollars in the US alone. African violets are
a very important gift plant for Valentine day, Easter, and Mother's Day but gardeners purchase this plant every
week of the year.
Here are a few facts that will help you to have the best African violets in the home.
1} Temperature is most important and the plant will do best if the day time temperatures averages 77 degrees
and the plant should be kept between 75 and 80 degrees during the day for the best foliage development and
flower bud development. Day time temperatures above 85 degrees will cause quick bloom flowers for short
periods and poor foliage development.
Night time temperatures should be 68 to 70 degrees for the best growth and flower development, so you can
see these plants do best with above average temperatures at night. Your plants will still grow well but not as
quickly and flower less often and the flowers last a shorter time in bloom.
2} Light is also very important and for these reason the plant can become basically shade-adapted very easily
and quickly to any home when brought home from the greenhouse. Light intensity is the primary factor regulating
both time of flower and the number of flower produced. In the fall and winter months give the plants more light
due to the shorter days by keeping it near a south facing window or under grow lights. During the spring and
summer lower the direct light intensity due to long days and hot sun, this will help to cool the plant down and help
it stay productive.
Plants that receive too much light will produce hard brittle growth and foliage and can become stunted with short
stems and bleached foliage. During the hot and sunny days of summer the sunlight can and will burn both the
foliage and flowers of your plants. Plants without enough light during the fall and winter will develop long leaf
stems, large thin leaves, and few flowers on the plant. If you're growing your violets under lights they must be
12 to 15 inches from the plant and be on for 14 to 18 hours especially during the winter months.
3} Humidity will depend on light, temperature and the season. Violets require less humidity during the short days
of fall and winter and more humidity during the hot day of summer. NEVER water the plants at night and keep
to foliage DRY or Botrytis fungus will infect the flowers.
4}Potting soil is also important with the African violet as they have a fine root system and require a well-aerated,
well-drained soil with a lot of organic matter. Use a special African violet potting soil or the Black Gold potting
soil as it has all the qualities that the violets require to grow properly. Artificial/ man made soil like Black Gold
is much better than a real dirt type potting soil and stay away from heavy soil made from mushroom soil mixes.
5} Fertilizer for African violets is different than most plants because they are light feeders. They prefer a slow
steady supply of food from a balance fertilizer such as 15-30-15 or a time release fertilizer like Dynamite that
will feed your violets for up to 6 months without any burning or over feeding the plant.
6} Watering is also important and your violets will thrive when the soil is maintained uniformly moist.
Never saturate the soil for any length of time and never let the plant sit in a saucer of water for long periods.
If you allow the soil to dry out and the plant wilts the growth will become stunted and possibly never recover.
This happens because the fertilizer in the soil can burn the roots and if you're keeping it wet the roots will be
deprived of Oxygen and Root Rot or Crown Rot will develop killing the plant. Check weekly and your plant
will thrive for you. If you have to water over the foliage, do it early in the day so the foliage has time to dry
before night time. Always use warm or tepid water when watering.
This is a great plant for even the novice gardener and it will give you many days and weeks of wonderful
foliage and flowers. Be sure to look for the new flower colors, and flower types such as the double varieties and
even bi-color flowers. Variegated foliage is also available and new mini varieties. This a great plant for a long
winter inside. Enjoy!!!
