Plant Identification and Knowledge (Horticulture II)

Become Skilled in Naming, Growing and Using Plants

This course is a natural progression from Horticulture 1, but can be taken as a subject in its own right. It concentrates on the identification, care and use of plants in a systematic way.

Plant knowledge learned here is in high demand in the horticulture industry. It is something prioritised by employers, but often not covered sufficiently well in modern horticulture courses.

"This is the first correspondence course I have done and I have thoroughly enjoyed it and I just wanted to say a big THANK YOU. I appreciate everyone's effort in such a professionally-run organisation with seamless administration. The office staff's happy can-do attitude, their fast responses to all queries, tutor Shane Gould's quick turnaround in assignment marking and his supportive and motivational feedback and last but not least, the sound subject guides. Most importantly I hope my thanks and appreciation can be communicated to all the staff who have supported me long the way of my learning! I work full time and study on the weekend but really don't stop thinking about what gardening solution I need in order to answer my assignments every day of the week. Thank you for such a great learning experience and I cant wait to start the second half of my course!!"

How Accurate are Plant Names?

Plants have two types of names -common names, and scientific names.

Common Names

Any one type of plant can have many different common names -sometimes dozens. Different regions within the same country can be using different common names for the same plant; and sometimes, even different people in the same street might use different common names for the same plant. Because of this -Coimmon Names are very unreliable for identifying plants.

Scientific Names

Scientists largely control the scientific names; and in theory, any one type of plant has only one scientific name; but in practice, there are sometimes conflicting points of view between scientists; and at times, nurserymen and horticultural trades people, are slow to accept changes made to names by scientists.

Nevertheless -scientific names are on the whole, the only effective way of identifying plants.

More about Why Scientific Naming can sometimes appear contradictory

Herbariums (at each of the botanic gardens) have always been influential in the naming of plants.

Problem is that as more people have become interested and involved with plants, large organizations (plant societies, horticultural associations, professional institutes) sometimes don't agree with the herbaria or botanic gardens.

Plant labeling companies sometimes don't print changed names on labels; preferring to continue selling already printed labels with old names.

Botanical and Horticultural Scientists sometimes come into conflict.

 "When I visited Honalulu Botanic Gardens 10 years or so ago, I met the director who was from Capetown South Africa. We disacovered that the two of us conflicted on a few names. After a bit of discussion it emerged that Honalulu (and his former employer in South Africa) were adhering to directions from the International Horticultural Congress who claimed to be the legitimate descendents (so to speak) of Linneaus. Interestingly though, on returning to Australia, the Botanists in Australia refute that and say their congress has the authority and the horticulturists are usurpers". (Quote: John Mason, 2006)

You need to be careful to make allowances and promote the taxonomic system as being the best and most accurate method of plant ID, but to point out that it can still occasionally have glitches due to these sorts of issues.

As you can see, there is more to naming plants than what first meets the eye.

HOW CAN THIS COURSE BENEFIT YOU?

If you already have the basics of horticulture - you may have completed Horticulture 1 or you may have completed a horticulture course elsewhere but realise your identification skills need improving then this course is for you. This course is a must if you:

• Work in a retail or wholesale nursery
• Want to extend your professional development
• Work in any aspect of horticulture such as gardening, grounds management, parks and gardens
• Would just like to improve your plant identification skills for your own pleasure and expansion.
