Develop a broad knowledge of African Violets and Related Plants.


African violets occur naturally is eastern tropical Africa (Tanzania and Kenya).

When African violets are grown outside of their "natural" environment, they need to be treated differently, but with adjustments made to compensate the changed conditions (eg. lower humidity, less natural light, colder temperatures), they are grown successfully in almost every part of the world.

Designed for the African Violet enthusiast this in depth unique course will teach you about:
  • propagation of African violets
  • cultivation health of African violets and pests
  • commercial aspects of growing African violets
  • You learn how African Violets are classified, and cover the exciting range of varieties available.

Here's your chance to achieve outstanding results with African Violets.

WHAT PLANTS DOES THIS COURSE COVER?


This course is focused mostly on African violets; but also provides an introduction and foundation for growing related plants that have similar cultural requirements and uses in horticulture.

These plants are members of the Gesneriaceae family of plants.
 
This family includes over 2,000 different species, spread across more than 120 genera. Around 300 or more of the species are in cultivation.
They occur mostly in tropical and sub tropical regions; though there are exceptions. The family has representative genera from most parts of the world, including Europe, Africa, Asia, America, Australasia and Polynesia.
Some of the genera (including Saintpaulia, Streptocarpus and Sinningia have been widely bred to produce thousands of different named cultivars; some of which have become commercially important plants.
The first gesneriad that was identified was Ramondamyconi, from northern Spain and the Pyrenees. It occurs naturally on rocky cliffs.  It’s classification was confused at first. It was thought to be an Auricula at first, then Linnaeus in 1753 classified it as a Verbascum.  Eventually it was recognised to belong to a different family to those plants.

Gesneriad Characteristics
 
Most gesneriads have fleshy tissues -not woody. They are generally herbaceous or only slightly woody.
Occasionally they may be tuberous, commonly they can be epiphytes, on rare occasions they may be a shrub or climber.
Leaves are usually opposite and simple. The leaf margin is most often entire or toothed. The leaf surface is commonly hairy, but not always
Flowers are cymose, usually irregular, bisexual (female and male parts in the same flower), with five petals, 5 sepals and most commonly two or four stamens (but sometimes five stamens).  Flowers are often twinned.

WHO CAN BENEFIT FROM THIS COURSE?

Nurserymen, florists and indoor plantscapers who deal with African violets on a daily basis may use this course to expand their knowledge and awareness of gesneriads.

Amateur and professional plant collectors and gesneriad lovers may use this course to indulge their passion.

For some, studying this course is a starting point for a life long exploration of gesneriads; while for others, it can be a vehicle to fill in gaps in their existing experience and knowledge.

By committing to such a specialised study program on just one type of plant, you will be laying the foundation to develop a real level of expertise with these plants. Such specialised knowledge is valuable and has the potential to be a career or business advantage for anyone working in horticulture.
