A really good website for information on conifers. It provides the basic information such as hardness zone, growth shape, etc, along with photos and a description of the tree. It is very helpful source to begin to understand the terminology of conifer leaves. It is very specific with respect to size of cones and needles and it would be nice if it had more close ups of the needles and cones themselves; it is very focused on the habit. But other than that, a great source.

I think this is a great resources. I like it because it talks about conifers in the garden and so there is discussion about their form and how it fits into the landscape and design. It covers the main conifer genus’ and has specific information on the different species. The photos are a great addition and show how the conifers look through different seasons. The only downside is that it does not have all the main species we looked at and lacks some of the more specific detail such as water use. I would definitely recommend this book.

A basic conifer ID site. Each species is only given a paragraph of information and it contains none of the detailed information we need. It also only provides one photo for each tree and it is of the form instead of ID features such as needles and cones. The nice feature that it does have is the compare page where you can compare different tree forms but also different genus and cones, leaves, etc.
