My wedding is to take place in the backyard, and we have planned to surround the reception area with citronella candles. Moreover, to make the ambience perfectly romantic, I was planning to use potted flowers as centerpieces, and my boyfriend (who is also my would-be husband!) has advised to use daisy for it. However, I am inclined to get orchids for the centerpiece. I would therefore, like to get some expert’s advice over the right kind of potted flower for the centerpiece. In addition, I would like to know which flowers freshness would last long! Thanks.
