Can anyone tell me what the name of these flowers are?
The first one is Cardinal flower, Lobelia cardinalis. Second looks like Dayflower, Commelina is the genus, there is a native one and a non-native one.
#3 appears to be Sundrops, Oenothera fruticosa, a member of the Evening Primrose Family.
Here is a link that might be useful: Oenothera fruticosa
#1 is cardinal flower for sure I have been looking for a plant to get seeds from. I have a few things I would be willing to trade if your intrested. It is a shade woodland plant that likes its water.
