They all look great!

What has been putting me off trying a Casuarina is the length of the "needles". I would like to try a Casuarina because they do very well here in Qld. How did you get the "needles" to reduce to that short length?
Cheers, Frank.
Hi Raging Bull
Casuarina don't have needles. Pines have needles. Pines are a Gymnosperm (means naked seed and they don't have flowers, but cones). Casuarina are Angiosperms (means enclosed seeds and they are all the flowering plants). The division between Gymnosperms and Angiosperms is very ancient, and they have many distinguishing characteristics. Although Casuarina can look superficially like pines with needles, and their seed pods look like cones, the leaves are not needles and the seed aren't in a cone, but a hard dry fruit.The "needles" you refer to are actually branches and the little rings around them are where the leaves are. The leaves are minute and the branchlets that are green do the majority of the photosynthesising. I have observed pines and Casuarina's growing together in the median strip of the M1 around the Gosford exit, and I am awed by their similarity in appearance at certain times of the year. One of natures beautiful things, that 2 very distinct plants can form strategies of survival that bring their appearance so close together.
If you twist and pull above the ring where you want the branch to end, you will break the branchlet at that point and end up with a shorter branch. These points are called nodes and represents the distance between leaves as can be seen more easily on trees with larger leaves. (Not that it would be hard to have a leaf larger than a Casuarina's). The space in between is known as the internode. New branches will only form where there is a node, i.e. where a leaf is, or used to be. You can also cut to the shape you want, but you will get brown tips where the branches die back to the nearest node. (The same as any tree)
Hope this helps.
