I want to insert a word of caution here. Although opinions differ, most experts agree that Lucky Bamboo flower rarely and usually when grown outside. Most agree that mature very healthy plants have the best chance of flowering. There is strong evidence that even when grown outside, that direct sunlight is not a good idea for LB. Filtered and indirect sunlight is the safest option. Also I would like to point out that if you are thinking about moving your Lucky Bamboo outside to try to get it to flower, it is important to remember that many of us live in areas where temperature and wind conditions are not conducive to growing Lucky Bamboo outside.

Wow. That second one reminds me of a corn field. Are the flowers hermaphrodite or do they need both genders to fruit?
