Man I should spend more time in the Information section
"Xion's name was coined by Tomoco Kanemaki, one of Kingdom Hearts 358/2 Days's scenario writers and the writer of the Kingdom Hearts Novels. Tetsuya Nomura took a liking to it and notes that it has many meanings. Xion's name contains the Japanese words for "tide" (潮shio?), fitting the oceanic naming theme of Kairi and Naminé, and Aster tataricus (紫苑shion?), which, according to Japanese floriography, means "I won't forget you" or "remembrance". It is also revealed within the Secret Reports that her "original name" was "No.i", her ID as an experiment of the Replica Program. The "i" used here may have been in reference to imaginary numbers. It is also possible that this is a word play on the word ion since this is no.i backwards. This would make sense since an ion is an incomplete particle, much like Xion."
