You get D. trinervia to germinate at least? That's better than most people. I'm actually going to try to start some new pots this year. The seeds I sowed into my existing pot last year before summer didn't germinate until the start of winter. I read somewhere the seedlings do not tolerate flooding so no top watering and keep the water level well below the surface.
From my pot of unknown flower color D. scorpioides plants. To the eye it has a pink tinge to it that doesn't show in the photo.
The gamma on these photos always seems a little dark after uploading them to photobucket. I'm not sure if it is photobucket or the browser. The gamma is calibrated on my monitor to Photoshop's calibration tools and they look fine under all the image viewers and editors I have.
D. helodes time sequence. Not enough frames but it almost works despite the glitches from having to change the battery. I need to DIY an AC adapter for my camera. Otherwise the batteries go dead after a couple of hours. The OEM unit is $100.
