Sister for Lillian? Preferably a flower name?

I’ll maybe add Dahlia? I like all your options for what it’s worth!

How about Flora? Iris, Violet, Ivy, Rose spring to mind as botanical names.

Camila is a favorite of mine! Maybe Rose or Rosemary? I also like Acacia and Jasmine for flower names Also I think Margaret sounds nice with Lillian and I think I read that the French version Marguerite means daisy? Which would incorporate the floral theme while not being too flowery

Possible flower name combos:

Magnolia Pearl

Marigold Camille

Violet Rhiannon

Daisy Sienna

Iris Annabel

I love the name Poppy.

Lavender

Flora

Sage

Cynthia

Zinnia

Marigold

Calendine

Flowers names: Rosina, Roslyn, Rosamund, Primrose, Susannah, Daisy, Marguerite, Violet, Violetta, Ivy, Iris, Jasmine, Heather, Dahlia, Briony, Fern, Willow, Azalea, Florence, Poppy, Ren, Liana, Myrtle, Yolanda

Related to Chloe, Dimitra is also associated with Demeter goddess of agriculture which might fit!

Erica is a genus of several flowering plants

ETA: Didn't realise Penelope was a type of rose! So pretty!

I always liked Hyacinth as a floral name and have only ever met one!

I love Camilla, though I think it’s pretty high up on the US popularity charts. Camelia also comes to mind because it is a similar sound and a flower name. My next favorite on your list is Sienna.

Laurel or Aster would be beautiful!

You already used Rosalie but what about Rosemary?

Are you due in February? Iris is the birth flower for February.

Iris Rhiannon

Violet Rhiannon

Camila Rhiannon would be cute, I assume you'd be pronouncing it cuh-MEE-luh? I know one little Camila, she's a cutie.

Iris, Primrose, Lavender, and Clover.

Camellia Pearl

Cassia Pearl

Cecelia Pearl (after variety of heather flowers)

Magnolia Hazel

Marguerite Hazel (French name for a type of daisy)

Susannah Pearl (floral meaning in Hebrew)

Violet Rhiannon

Would you consider other nature inspired names?

Savannah

Laurel

Heather

Marina

Maizie

Sierra

I think these work well with Lillian/Lily without being obvious themed names. Also, they are common enough to not be mispronounced but don't live on the top 20 list.

Out of your selection, I like Calista Pearl. Love Rhiannon, but doesn't seem to flow exceptionally well with any of the first name picks. How about Flora? Ivy? Iris? Daisy?

Primrose May (like Mayflower).

Nn Rosie or Posie!

Ffion is Welsh for Foxglove and Celyn is Welsh for Holly (but also widely used for males if that’s a consideration you want to make).

Angourie! (An-gow-ree) rhymes with flowery and also the name of the beautiful actress Angourie Rice.

I almost went with Kalina for my little girl. It’s polish and is a type of flower. Definitely not a common name in the US. And I loved the nickname options of Kali or Lina!

I love Sienna for a first name, but some other options might be -

Lillian and

Dahlia, Primrose, Cassia, Flora, Lavender, Jasmine, Wisteria, Violet, Roisin, Evanthe,

May i suggest bird names to coincide with the flower name?

Evelyn for instance.
