Tree ferns

In my last post Animal or vegetable, the “tree” that was featured is in fact not a tree, but a tree fern.

According to Wikipedia:

Some species in the Cyatheales have tree-like growth forms, but others have creeping rhizomes (stems). Some species have scales on the stems and leaves, while others have hairs. However, most plants in the Cyatheales are tree ferns and have trunk-like stems up to 20 meters tall.

Tree ferns are found growing in tropical and subtropical areas as well as temperate rainforests in Australia, New Zealand, and other island groups nearby; a few genera extend further, such as Culcita in southern Europe. Like all ferns, tree ferns reproduce by means of spores developed in sporangia on the undersides of the fronds.

The fronds of tree ferns are usually very large and multiple-pinnate but at least one type has entire (undivided) fronds. The fronds of tree ferns also exhibit circinate vernation, meaning the young fronds emerge in coils that uncurl as they grow.Unlike flowering plants, tree ferns do not form new woody tissue in their trunk as they grow. Rather, the trunk is supported by a fibrous mass of roots that expands as the tree fern grows.

We have several of these tree ferns growing in our garden next to our garden walls. The high walls provide shelter from the sun and the wind, as well as a moister environment.

The tree fern in this photograph (the one from my previous post), had been growing under the roof and once it hit the bottom of the roof overhang, it grew sideways. We've since transplanted it, but it's still growing skew. ©LB/notesfromafrica.wordpress.com

      They have grown a lot since we moved in, haven’t they? The local gardens are doing really well lately – we’ve been getting pretty regular rain this year.

    I love tree ferns. There’s a lovely one here at the Lucky 5 Star.

      I like them too. Pretty unusual to have them as garden plants – they look more like they belong in a forest or jungle. As Jacquelin says below, like a scene from Jurassic Park.

    Those ferns look like they could be right out of Jurassic Park!

      I actually remember seeing tree ferns in Jurassic Park. They date back many thousands of years.
