Hey Neppie,
Havron (Shawn) sent me some, which I quickly killed.
BUT, a 1 inch piece survived and now fills up the whole length of a ten gallon aquarium! This is just a single plant...and I'm not sure if it would be possible to divide it...hmm...
You may want to PM havron about it. I have not seen him on the forums lately (but I have yet to check general discussions), however.
But be warned! U. radiata is not easy to grow. It requires a larger container, at least ten gallons but ideally, bigger. It is sensitive to algae and hates humans, particularly me.
Cultivation: thoroughly mix one cup peat per gallon of pure water. Shawn suggests using 1/2 cup instead. Because Shawn's and D'Amato's opinions conflict, I actually use 3/4 cup.
Pour this mix into the container and just leave it there for at least a few days, allowing it to clear and adopt the yellowish complexion safe for U. radiata. After the water clears, carefully add the plant--don't dump it in!
It is a much better idea to NOT put the tank in sunlight--algae will form fairly quickly, killing the plant unless you act fast. Instead, use cool white fluorescent bulbs. I'm using only two in fear of algae, but four bulbs would probably be better.
Keep the tank in a room with an average temp; a cool room (e.g., a bedroom) would be best.
Then there are Co2 generators...I'm not going to advocate the use of one because 1) U. radiata does not appear to need one and 2) the yeast generator is what killed my original plants. The infamous 'siphon' ocurred, which brought yeast into the tank, causing algae to form, killing most of the small plants I had just received.
Ironically, a siphon is also what I used to remove the algae-infused water from the tank.
Do not fertilize! The dreaded algae, remember. However, U. radiata will not grow well unless it is fed, preferably with Daphnia, available
here. Use D. pulex, not sp. magna.
I'm not trying to discourage you, but aquatic utrics are notoriously tough to grow. See
here.
Good luck!
