There’s some evidence, but not a definitive conclusion. One study focused on trees that don’t produce anthocyanins. Anthocyanins are pigments that make leaves turn red. The study said that these trees don’t absorb as many nutrients as trees with red leaves.
Another study found that insects are generally not inclined to eat red leaves on trees. There seems to be a trend that suggests that red leaves are important for the trees’ survival in the fall. This trend needs to be validated by conducting more tests.
Yeah, there is far too much proof, perhaps too much. A great many people in the whole scan showed why crimson leaves help the plants. (Because it's a little longer you ought to carry some information aside.) They should remove a few of the information because it's a bit confusingly worded (if you published this blog post).
This is the best answer I can find. After reading it over multiple times I shortened it down to the word Delicate. It makes it sound like she want's this gown.
