The Undead Tribe obviously wouldn't care how the Tower of Nature, which is both elf and mage, faces the challenge of transforming the natural environment to be cleaner and more tasteful. Since they know it won't affect the people they care about, they quickly discard this issue.
Although everyone knows, if it were Hill, he wouldn't even need to consider how to cultivate these plants and could come up with a solution.
Having traversed many worlds and acquired significant knowledge in Toril, Hill's understanding of plants might even surpass that of the Nature Goddesses.
After all, their Little Bear truly bows tenderly to the world, never thinking anything is without value.
Hill may detest evil people, but he never denies their existence.
Therefore, even though he treats others with kindness, far better than those so-called Kind Alignment in Toril, Hill's faction remains Neutral because he never shouts for the destruction of evil as soon as he encounters it.
