Indeed. To me, a lot of stuff like this (the kind and color of a blooming flower) is basically a way for the author to create or maintain an atmosphere/background to the book. Mentioning flowers a lot makes it clear this is not an action packed plot driven thriller. Mentioning military ranks and insider jargon and abbreviations paints a military atmosphere. Basically a lot of words are “set pieces”. Very important for the general atmosphere but not overflowing with meaning and significance per se.
