Hi chiligirl,

My attempts to id the plants:

1. The reddish plant with the large oval leaves is either Ludwigia repens or L. palustris.

2. Hemigraphis colorata or lobelia cardinalis???

3. Crypto retrospiralus or C. balansae

4. Rotala rotundifolia

5. Bolbitis heudelotii

6. Hygrophila corymbosa

7. You are correct.

Tip: go to Image hosting, free photo sharing & video sharing at Photobucket and sign up for free account. Upload pics to that site and then cut and paste the URL provided for each pic in your thread here. I learned this just the other day

Tip: Identify plants, THEN bring home......

Good luck to you.
