Centerpieces & Favors...

I am getting married next year. I am having a garden reception but getting married in a Church. I had finally decided on the centerpieces and but wasn`t sure if it would be too much. I wanted Lucky Bamboo, really tall ones in tall thin vases. I wondered if it was too much because I found heart shaped lucky bamboo that I am putting in personalized bud vases and that is what I was giving out to the guest at the wedding. Someone told me that it was too much. I guess I was looking for something that people didn`t have to really take care of like a real flower or plant but also something to stick with my theme. The lucky bamboo needs no sun, dirt and it will be in the vase with river rocks and a little water. I had even thought that it would be nice to stick a poem on it that basically said as long as you follow the instructions this plant will grow, the heart will grow symbolizing that our love will continue to grow as well. But they still think it is too much. Please let me know maybe there is something else that I can do. Thanks.
