Plant Knowledge is the Foundation for good horticulture

A home garden can commonly have hundreds of different plant species growing in it. Public gardens may have even more. A plant nursery may be selling well over a thousand different cultivars, and sometimes many thousands.
Every plant will grow differently, and to get the most out of the plant, it requires a great deal of knowledge about the different plants you work with. This "plant knowledge" is what distinguishes the best gardeners and horticulturists, from everyone else.
Our courses place a great deal of importance upon teaching you "plant knowledge", perhaps more so than most other horticultural schools. In doing so, we believe that we equip our students with a distinct advantage over students who graduate from other colleges.
How much do you know about Plants?


A comprehensive guide to successful planting in the shade

A shaded area not only looks better with the right plants, but is also easier to maintain. Pants have varying degrees of tolerance to sun and shade, and information about what will grow best in your shaded area is hard to give, because there are so many variables involved.

The plants on the following lists are a good starting point. All have some degree of shade tolerance, and many will grow across a wide range of different climates. Before making your final choice, try to find somewhere where you can see the plants you choose, growing in your locality – perhaps in a botanic garden or a nursery. This will help you get a better idea of just how much shade the plant will tolerate in your part of the country.
