I love your style, you can’t really go wrong with a list like this. I especially like [name_f]Poppy[/name_f], [name_u]Sage[/name_u], [name_f]Olive[/name_f] and [name_f]Lily[/name_f] for [name_f]Rosemary[/name_f]’s sister.
I think I’d avoid [name_u]Sage[/name_u], in case you have a son in the future and still want to use [name_u]Basil[/name_u] – it just might be a bit much to have three herb names.
The ones that match [name_f]Rosemary[/name_f]’s vibe best are [name_f]Iris[/name_f], [name_f]Lily[/name_f], and [name_f]Olive[/name_f], I think. Though I love sound of [name_f]Rosemary[/name_f] & [name_f]Hannah[/name_f] together, I wonder if [name_f]Hannah[/name_f] might feel out of place with [name_f]Rosemary[/name_f] & [name_u]Basil[/name_u] (again, assuming you could have a son someday). [name_f]Luna[/name_f], [name_u]Piper[/name_u], and [name_f]Poppy[/name_f] don’t complement [name_f]Rosemary[/name_f] at all, imho – just too stylistically different and modern-sounding.
Iris gets my vote, overall. Still, I do like [name_u]Lark[/name_u] and [name_u]Wren[/name_u] a lot! They don’t have the same vintage vibes, but the nature tie is still there, so either of those could work well, too!
With [name_f]Rosemary[/name_f] I love [name_u]Lark[/name_u] [name_f]Iris[/name_f] [name_u]Wren[/name_u] and [name_f]Olive[/name_f] the best! [name_f]Lily[/name_f] and [name_f]Luna[/name_f] are so popular right now, [name_u]Sage[/name_u] is a bit much with [name_f]Rosemary[/name_f] and [name_u]Basil[/name_u], [name_u]Piper[/name_u] and [name_f]Poppy[/name_f] are cute but a little too cute next to [name_f]Rosemary[/name_f], and [name_f]Hannah[/name_f] feels boring next to the others.

I love [name_u]Basil[/name_u]! And love that it’s a family name. The spice theme is actually really cute intentional or not.
Here are my thoughts on your girl list-
Lark-This is honestly not my favorite. It’s just a little abrupt & harsh next to the classic feminine [name_f]Rosemary[/name_f]. But if you love it, it’s not awful. It’s unique & has pretty bird imagery.
Luna-This is far from unique. [name_m]Way[/name_m] popular…especially for dogs. [name_m]Way[/name_m] trendy & modern next to [name_f]Rosemary[/name_f].
Iris-I’m not a huge fan, just because it sounds harsh & I prefer softer names. But it is vintage & floral & goes really well w/Rosemary. Not a bad choice at all.
Sage-Another herb! That’s cute, but I find [name_u]Sage[/name_u] a bit bland personally. It’s not awful again…just fine. [name_m]Just[/name_m] not my cup of tea.
Olive-I love love love it. It’s vintage, quirky, smart, feminine, simple but not terribly over done. [name_m]Just[/name_m] perfect w/Rosemary too. And the nn [name_f]Livy[/name_f] is so sweet.
Piper-Meh, this is just not a pleasant sounding name to me. Kind of trendy too.
Poppy-Cute, but I feel like it’s too cute. I like it as a nn for [name_f]Penelope[/name_f].
Wren-See [name_u]Lark[/name_u].
Hannah-Beautiful classic. Kind of over done, but a nice name none the less that I think goes great w/Rosemary.
Iris and [name_f]Olive[/name_f]!
[name_f]Guinevere[/name_f] suits a sister to [name_f]Rosemary[/name_f]. I especially like [name_f]Ginny[/name_f] and [name_f]Rosie[/name_f] if you’re into nicknames
Lark is especially cool as a middle name. I like [name_f]Hannah[/name_f] [name_u]Lark[/name_u]. If you want to stick with the herb theme ([name_f]Rosemary[/name_f], [name_u]Basil[/name_u]), [name_u]Sage[/name_u] is a good choice.
Not sure if it’s been mentioned but how about [name_f]Saffron[/name_f]! [name_f]Saffi or ffion as nicknames[/name_f] and [name_f]Rosemary/Rose[/name_f] would make a lovely sister sibset. Good luck. Let us know what you decide.
I also think
Marigold would be lovely too.
Olive, [name_f]Guinevere[/name_f] and [name_f]Hannah[/name_f] all work really well with [name_f]Rosemary[/name_f].
How about [name_u]Larkspur[/name_u]? It would sound darling with [name_f]Rosemary[/name_f] and would create the cutest nicknames ever! [name_u]Lark[/name_u] and [name_f]Rose[/name_f]
Sage and [name_f]Rosemary[/name_f] is too “herby” for me and seems to follow a theme. [name_u]Wren[/name_u] and [name_f]Rosemary[/name_f] just don’t flow well when said together, and [name_u]Piper[/name_u] and [name_f]Rosemary[/name_f] don’t seem to match.
