Below is a shopping list if you’re wanting to create a bonsai pinetum. You may want to explore alternative species to include, if so the Gymnosperm database is a fantastic resource. ARAUCARIACEAE Monkey puzzle tree (Araucaria araucana) and/or Wollemi pine (Wollemia nobilis and/or Kauri (Agathis australis) CUPRESSACEAE Basic (5 genera): Hinoki cypress (Chamaecyparis obtusa), Dawn […] Read more… >
A pinetum is an arboretum, or collection of trees, dedicated to conifers. There is a fabulous pinetum at RHS Wisley in the UK (my ‘About Me’ pic was taken there), and the UK National Pinetum at Bedgebury Forest has a collection of 12,000 specimen trees. Whilst very few of us have the space to create […] Read more… >
Flat leaves are found across the conifer families including Taxus, Cephalotaxus, and even in Pinus (check out Pinus krempfii) as well as many of the Araucariaceae and Podocarpaceae families. Commonly known trees with this leaf shape include all varieties of yew, swamp cypress, dawn redwood and coast redwood. Here are some examples: Conifer flat leaves […] Read more… >
I’ll be honest, I find conifer needles to be quite weird. As someone raised in the southern hemisphere, true pine trees were something we had at Christmas and that was about it (this is true because the most common Christmas tree found in Australia is Pinus radiata). But actually, needles really are just plain old […] Read more… >
Scale leaves are a curious form of conifer leaves which cover up the stem in interlocking patterns. I believe they are called ‘scale’ because they look a bit like fish scales in the way they overlap but I have not found an authoritative source which confirms this. Scale leaves appear primarily in the Cupressaceae family […] Read more… >
I’ve been planning a post on this subject for a while because conifers have always been a bit scary to me from a bonsai point of view – they don’t seem as forgiving or obvious in terms of their growth behaviour. This was one of those subjects which ended up being a lot more interesting […] Read more… >
Rauh’s model represents the Cupressaceae family (cypress, juniper & redwood), some Araucariaceae, the Pinaceae family including most Pinus species, the Podocarpaceae family as well as angiosperms such as oak, maple and ash. It is a very common model for trees we encounter in bonsai. The architecture according to Rauh’s model includes a monopodial trunk (one […] Read more… >
This architectural model is associated with many conifer families including Abies, Picea, Sequoia, Metasequoia, Cedrus, Taxodium, Taxus, Cephalotaxus, Ginkgo & Ilex aquifolium. The pattern for this architecture is a vertical, dominant trunk with rhythmic growth and which consequently produces regular tiers of branches at levels established by the growth of the trunk meristem. Branches are […] Read more… >
Life on earth is classified into different categories and the process of doing this is the science of taxonomy. There is a lot of interesting history associated with biological taxonomy but my goal with this post is to show where trees fit into the taxonomy of life. Plant taxonomy is governed by the International Code […] Read more… >
Gymnosperms relevant for bonsai include ginkgo and the Pinales order (Araucariaceae, Cephalotaxaceae, Cupressaceae, Pinaceae, Phyllocladaceae, Podocarpaceae, Sciadopityaceae & Taxaceae – this is explained in The kingdom Plantae and where trees fit in). Ginkgo is a special case described separately at the end of this post. So what we’re interested in in bonsai is where lateral […] Read more… >
