Only after vascular tissue and after that roots evolved could trees evolve. After the invasion of land by plants a big adaptive radiation followed, in Devonian times. The first trees (big plants [30 meters] with woody stems) evolved about 360 million years ago and had roots and leafs (begin carboniferous).

Why did palm trees evolve to be so tall?
Answer: Palms compete for light by growing tall and fast. In this case, they overreach the (ordinary) deciduous trees by growing up and through the canopy to reach the pure sunlight above the shade cover of the deciduous trees.
How ancient are palm trees?

[Are Trees Vegetarian?] Most trees lay down rings as they grow every year.
Why do palm trees grow like that?
Palm trees are angiosperms, which means flowering plants. They are monocots which means their seeds produce a single, leaf-like cotyledon when they sprout. This makes palms closely related to grasses and bamboos. Palms can grow very fast.
What did the first tree ever look like?
From a distance, the trees would have looked like palms, with bases up to a metre in diameter. There were no leaves as such, just branched twig-like appendages which presumably had a photosynthetic function in the carbon dioxide rich atmosphere of those times.

One of the first kinds of large trees was Archaeopteris (if you google that name you can find more information easily). In the carboniferous important swamp trees were lycopods. There were also calamites the size of a small tree (horse-tail related).
Which flowering plant evolved over conifers?
A third factor (private communication with Dr C.V Looy) is the more efficient vascular tissue flowering plants evolved over conifers. At the end of the mesozoic era, 66 million years ago, gymnosperma trees have largely take over from the conifers.
What dominated the Jurassic period?
The cycads dominated the jurassic period though, along with ferns and dinosaurs. During the end of the mesozoicum, the cretaseous era, conifers take over as dominant trees from the cycads for a hunfred million years or so. Then about 100 million years ago the flowering plants, angiosperms, appear.
What two groups of plants were found in the Permian period?
The arborescent lycopds of the carboniferous coal swamps disappeared before the end of that period. The Permian saw the spread of conifers and cycads, two groups that would dominate the floras of the world until the Cretaceous period with the rise of the flowering plants.
