Feyplants can be both useful and dangerous.

Feyplants (魔木, maboku) are plants that contain significant amounts of mana and behave in an extraordinary way.

Feyplant Species

Name	Location	First Mention	Information
Batensell	Ahrensbach/Alexandria	Part 5 Volume 12	Little is currently known about Batensell other than it being a kind of feytree, whos blossoms are used to create Alexandria's midnight blue coloured duchy base dye
Behankraut	Ehrenfest Central District	Part 4 Volume 4	Behankraut is a common ingredient for lower-grade rejuvenation potions. It is one of the feyplants that grow in the noble forest in the capital's Noble's Quarter.
Blenrus	Haldenzel	Part 4 Volume 4	Blenrus is a feytree native to Haldenzel and growing in spring and early summer, once the last snow has melted. Both the tree and its fruit have a golden glow. The fruits are very sweet and rich in earth mana, making them exceptional material for both desserts and potions. Utilizing the fruit, Ferdinand is able to improve his extremely effective but repugnant rejuvenation potion to the point of tasting good, while still retaining its potency. The leaves can also be used to make tea that is naturally sweet. Unlike most other trees, Blenrus do not grow from the fruits, only grow sprouts near the parent trees by means unknown to men. Such sprouting is exceedingly rare and only a single instance has happened in living memory, when High Bishop Rozemyne and the female nobles of Haldenzel accidentally activated an ancient magic circle during spring prayer and brought forth an early spring. Due to the immense value and scarcity of the fruit, it is forbidden to share them with people from outside of Haldenzel, with very few exceptions. The only known specimen in the province is heavily guarded.
Effon	Illgner	Part 3 Volume 4	Effon (エイフォン, Eifon) is a feyplant found in Illgner. The effon is a "singing tree" found in the mountains of Illgner. If it is alone, the effon will sing quietly to itself. However, if there is more than one effon within hearing distance of each other, they will sing louder and louder to be heard over each other. As they can become very noisy in large groups, the people of Illgner consider them a nuisance and will usually cut them down. The sound is actually produced in the hollow of the tree, and while the way they sing sounds rhythmic, there is no real melody. Rozemyne notes that she is not sure why a tree would want to be heard.
Flammerzung		Part 4 Volume 7	Flammerzung is a feyplant. Currently very little is known about it apart from its fruits being a valuable ingredient for Magic Potions or Magic Tools. The blue fruits are very rich in fire-mana, but do not have a particularly high purity.
Granaruke	Ahrensbach/Alexandria	Part 5 Volume 12	Little is currently known about granaruke, other than it's fruit being an ingredient for Alexandria's midnight blue duchy base dye.
Gumka		Part 5 Volume 3	Gumka is a feytree. When not threatened it looks like a regular tree, but if it is attacked, it can extend many tentacle-like branches that are usually hidden underneath it's thick foliage, which makes it look aking to a jellyfish when it's defending itself. These long and thin branches are covered in thorns, tipped with a paralyzing poison strong enough to make anyone hit by them lose all feelings in their limbs. The branches can only be cut when the tree is flinging them out to attack, but not when it retracts them around it's trunk. While they are retracted, the tree's very top will shine and grow new branches, though unless the leaves are burnt away, this light can not be seen through the thick foliage. Near the top of the three there is a differently coloured spot, which seems to be where the tree stores and generates it's mana. It is this spot that lights up when the tree is regrowing lost branches. When the branches are retracted around the trunk, hitting this spot will disrupt its attempt to grow branches and make it attack again, presumably while building up mana for the next attempt to grow more branches. In a regular hunting party, the branches will be cut down primarily by lay- and medknights, while the archknights build up mana to attack the weakspot in succession once the branches are retracted. Anything short of the strongest attacks on a gumka do not produce a shockwave, likely due to the bark having rubber-like qualities. It is possible to harvest a rubber-like substance from the tree, though it is currently unknown how one would go about that, since at the moment the only fight with such a feyplant ended with its destruction.
Kurhaize		Part 4 Volume 4	Kurhaize is a feyplant that is the evolved form of eise. It is rich in yellow wind-mana and oil extracted from it is used to create magic ink.
Nanseb	Illgner	Part 3 Volume 4	Nanseb (ナンセーブ, Nanseebu) is a feyplant found in Illgner. This is a species of parasitic plant that latches onto the roots of a large tree and injects its seeds into the roots. As the plant grows, it absorbs the nutrients of the tree until it is mature, then it pops out of the tree and walks away to find a new host to infect. They are slow-moving and quite easy to catch, but their roots must be cut off when harvesting, as they can absorb nutrients from nearby plants. They are considered pests by the residents of Illgner, and are used in the paper production by the Rozemyne Workshop. When paper made from Nanseb is cut or ripped into pieces, the individual pieces will slowly move toward each other and gather around the biggest piece.
Parue Tree	Ehrenfest Central District	Part 1 Volume 1	Parue Trees are trees that only grow on clear winter mornings and look like an ice-sculpture of a tree. They quickly sprout and grow parues, their fruit. They suddenly stretch out and wave around once the sunlight directly touches them near noon, flinging the parue fruits far and wide, after which the entire tree melts back into the ground. Commoners harvest parue fruits as their juice and oil are great as food, while their shell can be made into chicken feed. The trees are very hard in the cold and any fire brought near them is instantly extinguished, thus the commoners use their hands to warm the branches until the parue fruits fall to the ground. Where the fruits that are not gathered by people land, they are absorbed into snow, leaving only the seed behind for the next spring. When the noble children taken in by the temple after the purge of the former Veronica faction accompany the other orphants to gather parue, they tend to melt the branches noticably faster than anyone else, which makes it likely that a higher mana capacity speeds up the melting process beyond what just regular body-heat is capable off.
Quellweide		Part 4 Volume 7	Quellweide is a feyplant. Currently, little is known about it other than its leaves being valuable ingredients for Magic Potions or Magic Tools. Its yellow leaves are very rich in wind-mana, but not of particularly high purity.
Rairein Flower	Ehrenfest Central District	Part 3 Volume 3	Rairein is a feyplant similar in appearance to waterlilies that grows in the Goddess' Bath in Ehrenfest's Central District. Its nectar contains very strong and pure water mana, particularly if gathered on the Night of Flutrane in spring. Upon absorbing mana, the plant can grow into size as large as trees, enough to carry a child on its leaf.
Ruelle Tree	Ehrenfest	Part 3 Volume 2	A Ruelle tree is tall with metallic branches. On nights with a full moon, they grow flowers similar to white magnolias. After absorbing enough moonlight, the flowers shed their petals and ruelle fruit begin to grow. When the petals hit the earth underneath the tree, they appear to melt into the ground. The fruits look like little yellow crystals and once exposed directly to the moonlight, they grow to be about 10cm in size. These fruits contain significant amount of wind mana of very high purity. During the Night of Schutzaria, the flowers emit a strong aroma, the ruelle fruits are coloured purple and have much more mana within them. This attracts the attention of a lot of nearby feybeasts to swarm around the tree and go into a feeding frenzy in order to eat the fruit.
Rungorb	Ehrenfest Central District	Part 4 Volume 4	Rungorb is the white fruit of a feytree. It is an ingredient for slightly higher quality potions commonly used by archknights. The fruits grow at a height where they are just out of reach of normal adults, requiring the harvester to climb the tree, get hoisted by another person or use their highbeast to fly up if there is enough space. It is one of the feyplants that grow in the noble forest in the capital's Noble's Quarter.
Schallaub	Ehrenfest Central District	Part 4 Volume 4	Schallaub is a feyplant that is rich in wind mana, commonly used as materials to make Ordonnanz stones. It is one of the feyplants that grow in the noble forest in the capital's Noble's Quarter.
Taue	Ehrenfest Central District	Part 2 Volume 1	Commoners throwing taue at the Starbind Festival Taue trees are seemingly normal trees in the forests, especially near the capital. They grow red fruits filled with water that can grow to about the size of an adult's palm. They are used as waterbombs by commoners in the capital during the Star Festival in summer, where the people start by throwing the fruits at the newlywed couples, before throwing them at anyone who's still dry once all the fresh couples have finished the gauntlet. Myne later finds out that when Taue fruits are exposed to mana sources, they will absorb it. Once sufficient mana has been accumulated in a fruit, it goes through a brief metamorphosis before exploding and shooting seeds in a small radius. These seeds then immediately start to grow into small Trombe when they come into contact with earth. Trombe and Taue are feyplants of the same species, but different genders. The seemingly harmless Taue trees are the females, producing the fruits, while the aggressive and dangerous Trombe are their male counterpart, which fling their spores far and wide while flailing around. Usually, fertilized Taue burrow underground and absorb mana from their surroundings for several years, before sprouting into trombe out of sight, which is why nobody before Myne made the connection.
Teigenehm	Sovereignty	Part 5 Volume 1	This tree grows in the gathering spots of the Royal Academy. The fruit is a valuable ingredient, but with the peculiarity that it can only be charged with one specific element at a time.
Trombe	Ehrenfest Central District		Trombe is a dangerous feyplant that can cause widespread devastation if left to grow and the male variant of the same species of tree as the Taue. See Trombe
Wehrnoor	Ahrensbach	Part 5 Volume 5	Wehrnoor is a flower growing in Ahrensbach during spring. It is an ideal ingredient for making protective charms.
