They called Viola or pansy . Hm, a nice flower for springtime.
Oh, I'd love pansies...they're such pretty flowers! They do come in lots of different colors, though.
Another reason that I like them is that in English, calling someone a pansy is an insult meaning that they're weak or wimpy. I just find it interesting to compare a person to a flower and think that it would be an interesting (and slightly humorous) addition to the game.
A very pretty, multi colored flower that we used to have in my parent's garden when we were little. It's the one where you pinch it on the sides and it opens up.
Dutchman's Britches is a relative of the Bleeding Heart flower that I think would be nice to have.
Jack-in-the-pulpit.
Okay, I am just listing flowers now.
Dogwood, azaleas, honeysuckle, Iris, violets...I'll be back with more ideas.
Sweet pea(Lathyrus odoratus) Pink is the most common color, but they come in many other colors too.
Morning glory Purple and light blue are the most common colors, but they come in a wide range of colors too. Below is one of my favorites
This is more common
Whoa, Annageckos! I have never seen one like that V before! Those are gorgeous!
I don't know if these have been suggested ot not, but I'd love to see a sunflower or a lotus, or maybe more fruit bearing flowers, like strawberries.
Oh, those are great suggestions, ThatOneGirl! 
Ach ja Sonnenblumen wären toll.
Das dachte ich auch gerade und es gibt so viele Arten und Farben
nicht nur gelbe. Es gibt ja auch rote und weiß- lila oder welche die wie kleine Büsche sind mit mehreren Blüten.
Hab sogar schon welche gesehen wo die Blüte gefüllt war also ohne braune Kerne.
Orchideen wurden schon vorgeschlagen, Rosen auch. Beides würde mir sehr gut gefallen! Stiefmütterchen sehen sicher auch sehr schön aus!
Was würdet Ihr von Seerosen halten? Ich liebe Seerosen!
Orchids and roses are already suggested. I'd like to see them in the game. Even pansies would look beautiful, I tihink.
What do you think about waterlillies? I love them!
Stiefmütterchen gibt es seit kurzem.
Pansies are available as of recently.
I would love to see irises in the game. My favorite flowers.
To be honest, I'm surprised roses are not available in game. After all, when asked to think of a flower, most people think of roses first...
Hmm ja. A rose in only one field where not good. A two fields height takes the place from two flowers. We hope, the team finds a way. Normally it needs two visible layers. 
I would love to see freesia among the Flowergame flowers ;)))
I'm so crazily happy about the liverleaf we got. It reminds me of the place where I grew up.
Could we please have the pink variant as well?
I remember some pink flowers in the endless carpet of purple liverleaf 
So much more difficult to find 
Seerosen finde ich eine sehr gute Idee. Aber vll. erst später? und dann bekommen wir doch bestimmt auch einen Teich und einen Fisch und einen Frosch. Würde bestimmt noch neben den tollen Wintergarten passen. Ich liebe Wasser.

I love irises too! My mother once decorated my birthday cake with her irses because she was all out of food coloring! It was the best birthday cake I've ever had in my life.
I'm surprised as well about the roses. I hope they work out whatever difficulty they have with it so we will be able to enjoy them here.
I also hope rose could work out without size issues. We have christmas trees with the size of crocus and porcini mushroom, and no one is upset about it, right?
I'd love to see some foxglove. Lovely plant and the colors are beautiful.
I'm a big afficianado of cactus, succulents, and other desert flowers. Here's a list:
Tiger Aloe
Yucca (huge stalk, between 5 to 10 feet tall.)
Century Plant (in real life it takes a full 100 years to grow, then it dies)
Old Man Cactus (the one I had used to have way bigger flowers than this)
Thistle
Some non-desert stuff.
Morning Glory (which has been suggested and has great photos)
Spider Plant (which would be great)
Snapdragons
Miniature Rose (lots of colors)
Poison Ivy? It's pretty.
How about some spicery/herbs to make a "kitchen garden"?
Like basil, parsley, thyme, dill, chive ...
I know that are no "flowers" in strict sense, but they are able to be in flower 
and I would love it! 
EDIT: And I like black-eyed Susan vine very much.
I finally figured out the name for this, it's Celosia.
While someone did suggest 'weeds', why not a new weed seed, such as Wild Mustard?
I don't know if you'll use shrub or tree ideas, but I've always liked Bottlebrush.
