Plants

Thaumcraft introduces several new plants, all of which have use in magic.

Greatwood Trees

These huge and distinctive trees are found in ordinary forests and occasionally other biomes, but especially in magical forests. With their 2×2 trunk and multibranched canopy, each tree can yield up to three stacks or more of greatwood logs. Their logs and planks are much-used in magical crafting, and the logs are a cheap source of Praecantatio essentia. Some greatwood trees are adorned with cobwebs, indicating a cave spider spawner and treasure chest beneath the trunk.

Silverwood Trees

These trees have distinctive white wood and bluish leaves, with magical lights glittering from the leaves and shimmerleaf flowers growing around them. They are found only in Magical Forest biomes (and if grown elsewhere, may create a Magical Forest biome around them, see below.) Their forms have changed somewhat over the versions, in 4.11 they are both tall and broad, with thick trunks and "root" blocks extending into the ground.

They sometimes grow with Pure Nodes embedded in a log (or even two) marked with a large black spot on the bark. This will result in a patch of Magical Forest around the tree, even within another biome. Their wood can supply both Praecantatio and Ordo essentia, and is used for several important magical recipes.

Shimmerleaf

Shimmerleafs only appear around naturally-spawned silverwood trees. They only appear with naturally-spawned trees, not when a silverwood is grown from a sapling. The flowers drop normally but can be crafted into quicksilver. A shimmerleaf flower can be crucible-crafted into the Taint-purifying Ethereal Bloom.

Cinderpearl

Cinderpearl appears in desert biomes. They are generated with the landscape and cannot be farmed. They drop normally as items, but can still be crafted into Blaze Powder. This allows producing a few special items such as Ender Chests before reaching the Nether.

Mana Pods

Mana Pods appear on trees in Magical Forests, on the bottom of a wood block. (Usually, this means they will appear on a greatwood or large oak tree, as only those trees are both present, and have wood blocks with exposed bottoms). Each pod has a magical aspect, and if ripe, they can be broken to drop one or two mana beans of that aspect. While wild beans only have primal aspects, with care and effort, they can be bred to supply essentia of any desired compound aspect. If eaten, mana beans will grant a research point and a random status effect, including dangerous or lethal effects.
