Thaumcraft introduces several new plants, all of which have use in magic.
These huge and distinctive trees are found in ordinary forests and occasionally other biomes, but especially in magical forests.
- They have a 2×2 trunk extending up to a multibranched canopy. Each tree can yield upwards of three stacks of greatwood logs. They can be grown by placing 4 saplings in a square, similar to jungle giants. (Single saplings will not grow.)
- Their logs and planks are used in magical crafting, notably the second-tier wand core. The logs are a cheap source of Praecantio essentia.
- The wood can also be used in ordinary crafting, but if the planks are further crafted into stairs or slabs, the result will be plain oak.
- Some greatwood trees are adorned with cobwebs. These have a cave spider spawner and a treasure chest beneath the trunk.
These trees have distinctive white wood and bluish leaves, with magical lights glittering from the leaves and shimmerleafs groing around them. They are found only in Magical Forest biomes (and if grown elswhere, 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). The log with the node will be marked with a large black spot on its bark. If a Pure node is not already in a Magical Forest, it will change the area around them into Magical Forest, and also defend a small area against Taint. As of 4.11, this only applies to pure nodes which are (still) embedded in silverleaf wood blocks, and jarring the node will destroy the wood block. Thus jarred or naturally "naked" pure nodes will not combat taint.
- They can be grown from saplings, but bonemeal will not work on them. The saplings are comparatively rare, with a low chance of dropping from leaves. However, silverwood saplings can also be purchased from Pech.
- As of version 4.11, silverwoods grown from saplings will not create shimmerleafs, which can only be found near naturally-spawned silverwoods.
- Their wood can supply both Praecantio and Ordo essentia.
Shimmerleafs only appear around silverwood trees. As of version 4.11, they only appear with naturally-spawned trees, not when a silverwood is grown from a sapling. Before 4.11, they would produce quicksilver when broken, and required shears to harvest. As of 4.11, the flowers drop normally, but can still be crafted into quicksilver. A shimmerleaf flower can be crucible-infused into the Taint-purifying Ethereal Bloom.
Cinderpearl appears in desert biomes. They are generated with the landscape and cannot be farmed. Before 4.11, they would drop Blaze Powder when broken, unless shears were used. As of 4.11, 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 appear on trees in Magical Forests. They can be planted on any log, but only in a magical biome; For basic Thaumcraft, this includes Magical Forest, Eerie, or Tainted biomes, but additional mods can add other magical biomes. (Note that they have no special resistance to taint, so they will be short-lived in a tainted area. Also, their wood will be turned to taint.)
When ripe, the pods can be broken to yield one or two beans. Each bean has a random aspect, which can be any of the 50 aspects. It does not matter what the "parent" bean's aspect was, and it is not possible to determine the bean's aspect by examining the pod. Mana beans can be distilled for their aspects (which can provide some rare aspects), or traded to Pech. Before 4.11, they could also be used to create Salis Mundus, used in advanced magical crafting. As of 4.11, ethereal essence is required for Salis Mundus.
As of 4.2, mana beans no longer have purely random aspects. When initially spawned in world generation, mana pods have a single aspect, and produce two mana beans of that aspect when fully ripe. Mana bean pods that are planted next to each other have a chance to cross-pollinate each other into mana bean pods of their combined aspects. Hence, if you plant an ignis mana bean adjacent to an ordo mana bean then they may merge aspects into potentia mana beans. This allows players to breed mana beans together to produce mana bean farms for aspects that are normally tedious to acquire, such as auram.
Mana bean farming may be automated by the use of golems, as they are recognized by the harvest core and are replanted with the ordo golem upgrade.
If eaten, mana beans can yield research points, but they can also give random status effects, including dangerous or lethal ones. (Note that certain mods such as Witchery may enable Harming as a continuing effect, which is rapidly lethal.)
