Well, speaking of naming plants...
My own personal impression is that I generally do not care to have plants named for
real people,
who I personally do not know, where the plant name includes their last name. I don't care how famous that person is. I know that it is meant as an honor and all that, but I just don't care for it.
This doesn't mean that I don't have exceptions to the rule, but there is generally a good reason for the exception.
Thus, in my garden I have:
...for color contrast, tall stalks, and its wonderful "spicy" carnation-like fragrance.
I'm not much for poetry (unlike DH), but I like Frost's poetry, and he taught for a while at DD's alma mater (there is a statue of him on campus, and there used to be a portrait of him in the library there), so there is some personal meaning there.
Plants that carry names for
fictional people (or animals), on the other hand, I am entirely fine with.
(I used to have this (eaten) and would like to reacquire it, but it's an example.)
The best explanation that I can come up with for this, is that I like the garden to be a "romantic" place, and also (in areas) a charming themed place. So plants named with a first name, or a first-and-middle name combination, or a first name and some attribute, work just fine, I think for "romance".
First and middle name... romantic.
First name and an attribute (in this case, iirc, the named person liked the "eye" on the bloom). (I don't have this plant, I just remember the name and thought it was a nice solution to partly naming a plant for someone.)
Themes can run the gamut. We have an extensive science fiction and fantasy library, so a lot of our plants have some relationship to that theme. DH very much likes poetry, so I have some plants pertaining to that. We are also a family of gamers (the games vary), so that factors into there also. And I like the Sierras, so some plants are chosen for that purpose.
A triffid is a science fiction menance.
The iris was named after the movie, which was in turn based on a science fiction novel (with a different name, which escapes me at the moment).
A beautiful iris, partly bought in fond memory of pinochle games played with DH's parents. (My parents also played pinochle, but they never taught me.
)
Because we are all game players (and that is how I met DH).
I generally do not like brown-ish plants, but this isn't, quite, and I purchased it as a memorial of hiking in the East Sierra.
All of the above leaves me with a potential quandary. I have/had the intention of naming some daylilies (or irises) after certain family members, and dogs, but I haven't yet come up with anything that I consider registration-worthy (apart from maybe one old red daylily seedling), and I am running out of time there. Naming a plant for a dog is not an issue... just combine the dog's name with some attribute of the dog. For people, I'd run smack up against my "no last name" thing. So do I name a plant for my sister, using her full name, her first-and-last name, or (my preference) her first and middle name?
