I got these seeds from Matt and they first germinated in early December 09. You can check out their early stages in my thread here: http://www.flytrapcare.com/phpBB3/i-can ... t3169.html (be warned, there are silly cat pictures)
As you can see, they've grown quite vigorously in the last few months. This picture is current as of today, March 30th. I've fed them betta fish flakes every few weeks and have kept them under a mix of sunlight and florescent light. The biggest leaves are about 1.5 - 2 inches long. I plan on separating them next week, about 2-3 plants per cup. The cups are 8.5 oz, if you're trying to get a sense of scale.
Drop me a line if you're interested!
