Quwi - The Survivor Tree

The fruit that nurtured a planet

Quwi saved the world from famine, but you must wait.

  Eating it too early will bring a deadly fate.
- Baduhmian warning poem.
  The Quwi, or Survivor Tree, was one of the few types of flora that not only survived, but thrived through The 30-Year Winter.   Originally a simple variety of apple tree, the Quwi was uniquely suited to the dismal cold. But the apple tree underwent some significant changes caused by the exposure to fallout from The Cataclysm. The trees became much larger, and the fruit and flowering changed significantly.

  The fruit can be extremely nutritious when ripe, and this nutritional value is what helped many Urnatis recover when they emerged from their shelters after the 30-Year Winter. But lessons were learned about the mutation as well.   If the fruit is eaten before it ripens, it can be deadly, as many Urnatis discovered. The unripe fruit has a poisonous trait that attacks the gastrointestinal system of most species, resulting in severe dehydration and stomach cramping, followed by extreme flatulence. If an individual can survive the poisoning, there is a high likelihood they will experience some form of nervous system damage, from memory loss and loss of body control to personality changes and physical tics.   The Quwibiril bird will eat the unripe fruit unharmed, but will not eat ripe fruit. This is the clue that fruit is safe to harvest. The bird's gastrointestinal tract features an enzyme that neutralizes the poison. The birds are partial to the male fruit, which contains the most seeds. This is the main method of propagation for the tree.   During ripening, the poison ferments and loses its toxicity. The intense flavor of the fruit, known as the Quwi Apple, is created by this fermentation. If the fruit is used as a base for a drink, such as a mead, the additional fermentation further intensifies the flavor, and creates a potent alcoholic drink. Animals who eat fruit that has fermented are often found acting strangely or asleep under the tree. More than one squirrel has eaten an overripe Quwi apple, only to fall from the the tree in a stupor.  
"These cursed rodents are always getting knackered on me apples. I hate havin' to step over 'em like furry puddles"
— Baduhmian Apple Farmer
  In the first years after the Cataclysm, Urnatis were unaware of the poisionous nature of the unripened fruit. Now, centuries later, deaths and even illness from eaten unripened fruit are rare, and usually happen with children who have not been properly warned away. Most children are taught fairly early that if the bird will touch the fruit, the child should not. In fact, children are encouraged to make water basins out of clay to attract the Quwibiril, who are an excellent indication of whether the fruit is safe or not.

Basic Information


Originally a fruit tree, the Quwi was genetically modified by the fallout of The Cataclysm. Trees survived the blast, but the genetic modifications caused it to increase from its original size by 5-fold. The original trees were 10-15 feet tall. Now the trees stand 50-80 feet tall. The trees were cold-hardy by nature, prior to the Cataclysm, which served them well during the The 30-Year Winter.   The trees form a thick trunk, with proportionally thick bark. The bark acts as an insulator, modulating extremes of temperature and protecting the tree. From the trunk, thick branches reach out horizontally. From these, thinner branches spread. Most are sun branches, filled with leaves to capture the light from the suns. The remainder are fruiting branches, which tend to be slightly thicker than solar branches to support the weight of growing fruit.   Solar branches do carry some of the male fruit, but as a rule, fruit is primarily found on fruiting branches.   Fruit only grows on lower branches, witht the top 1/3 of the tree devoid of fruit.

Biological Traits

The bark of the Quwi is very hardy, and works to insulate the tree. The bark generates from center of the tree outward, and after the 5th year, the outer layer is shed without harm to the tree. This shed bark is often collected and used for insulation in buildings and items such as mattresses. It is soft, and does not compress easily, retaining the air pockets that make it a great insulator.   The wood of the Quwi is a hardwood with fire resistant properties. It makes for durable furniture and construction, and burns poorly. However, the tree is also considered sacred, as many who survived the Cataclysm ate the fruit when they emerged from their shelters. Trees are not to be felled unless they have been damaged severely, have fallen of their own accord, or have stopped bearing fruit entirely.

Genetics and Reproduction

As part of the genetic modifications the trees underwent, the fruit was also modified. Whereas before the Cataclysm, male flowers carried pollen that would be transferred to female flowers, they have become hermaphroditic, and now the pollen is produced and pollenates within the same flower. The fruit however, does display difference in gender. The "male" fruit is smaller, and carries the seeds of the tree. The female is larger, with sweeter flesh and very few, if any seeds.

Growth Rate & Stages

The main trunk of a Quwi grows slowly, thickening to 10 inches across before any fruiting branches are set. The tree has an almost mushroom shape to it naturally. The canopy grows thick, which provides plenty of solar branches for growth and protection of the fruiting branches when they come in. It takes approximately 5 years for the tree to begin to grow fruiting branches, and at this stage, growth begins to accelerate. By year 5, the tree is approximately 10-12 feet tall. By year 10, however, the trees average 35 feet tall and are approximately halfway to full height. Trees reach their full height by their 15th year, stretching to as much as 80 feet tall and a canopy that spreads up to 65 feet in diameter.   Fruit set is vigorous, and is a reason for the tree's height limitation. Once a tree gains a certain size, the amount of energy directed to fruit production is sufficient to slow the energy directed to growth.   Quwi have been known to grow for hundreds of years, and a small grove near the Baduhm/Orsholon border has a few specimens that are believed to trace back all the way to the Cataclysm.

Ecology and Habitats

Quwi grow best in climates that feature at least 80 chill days per year. That is, at least 80 days where the temperature dips below 40 F/ 4 C for a period of at least 4 hours (320 chill hours).   Their size tends to occlude light, thus preventing any growth underneath them with the exception of shade-loving plants, such as ferns. They like firm soils that are well drained and do well in rocky and sandy soils. Growing in orchards is very difficult due to their size. However, some have been successful in creating platforms underneath the trees that allow access to higher branches for harvesting.

Biological Cycle

The tree is dormant through the end of the autumn months and winter. In early spring, new growth begins to form and new buds emerge from the branches. The majority of these will be leaf buds, which will grow to provide the energy required for setting fruit later in the year.   Summer is spent thickening and adding foliage, with the tree's energy focused on maximizing leaf and branch growth.   Late summer, the tree begins to set fruit. The male fruit set first, followed by female fruit 7-10 days later. The harvest is typically in late autumn, with all fruit maturing in a 2-week period.

Great article and great plant :D I like the fruit being poisonous unripen and the idea of the birds helping people see when it's ready. They better hope they have a lot of those birds in the region/in their garden so that they don't mistake the reason for their absence!   Here are my reactions while reading:   I'm guessing that the Catalypse is a nuclear disaster/attack? I'm also guessing that you haven't published that article yet and that’s why there is no mouse hover explanation for that. Still I think you could add one sentence about that in the article since it's an important event that had a big impact on your tree and you keep referring to it.   "The bark generates from within" I think you have "heat" or something else missing here. Or is it "is generated"? And in the same paragraph "items" is misspelt as "itmes".   In the second paragraph of the biological section "bearing" is misspelt. And I think you mean "fallen" instead of "allen"?   The Genetics section is missing a "was" before "modified" in the first sentence.   "Whereas before the Cataclysm, male flowers carried pollen that would be transferred to female flowers, they became hermaphroditic, and the pollen is produced and pollenates within the same flower." I was a bit confused by this sentence and I think you could change it to "Whereas before the Cataclysm, male flowers carried pollen that would be transferred to female flowers, they have become hermaphroditic, and now the pollen is produced and pollenates within the same flower."   I like the details that the production of fruits slows the growth of the fruit and limit its size.   For the temperature I'm guessing you mean degree Fahrenheit? I think it's best to precise which type of degrees since we have a very international community. You could also add a tooltip with the conversion into degrees Celsius.   "Their size tends to occlude light from any growth underneath them with the exception of shade-loving plants, such as ferns." That sentence is slightly confusing, you could write instead "Their size tends to occlude light, thus preventing any growth underneath them with the exception of shade-loving plants, such as ferns." And you misspelt "growing later in that paragraph".   I'm wondering how common the tree is. You mention it growing it in orchard, but would anyone have one in their garden for example? Is there any tree growing on the side of the roads? Also, despite the birds, how common are incident with people eating unripen fruits?   You could add a quote with parents' recommendations/teaching their children not to eat unripen fruits and to be nice with the birds so that they come to the house and the trees and can be used as an indication that the fruit is not mature.

This was a really nice article. The small poem was a great way to start. I liked the idea that the birds help the people to see if the fruits can be eaten.   The drunk animals and the quote about it was just great. You had me laugh while reading that one. Nice read!

These are neat, really useful food and interesting way to gauge whether it's safe to eat. Slight note: I spotted two 'the the'.
