Personally, I adore the fresh scent of citrus, lemon in particular! As a child I was bombarded with commercials on the tv, advising any housewife or child listening that lemony fresh was the best. I must have taken it to heart because I love lemons!
I love to decorate my tea table with whole lemons in a bowl, lemon wedges on a plate with a cute bird squeezer or this style of lovely arrangement! (when I have the time- 15 minutes- thinly slice two lemons and place along the inside of glass bowl -I use my lonely trifle bowl. Place flowers into center of lemon lined vase then fill with water.
Take this from me! Don't fill the vase of lemon slices first. Your hard work will just float away! The pro's use another vase, a wee bit smaller and place this in the center of the lemon lined vase to keep things lined up and perfect.
I do purchase ready made bouquets at my grocery store. I chose two that are basically the same and pull out the flowers that are not in my color scheme. Most times that leaves me with a lovely large arrangement of what the florist thought was "filler" flowers and foliage. This goes into my lemon lined vase and the larger remaining flowers go into a pretty pitcher or vase for my coffee table.
Remember that the rule of thumb for flowers on your tea table is to keep the scent to a minimum. Your tea should be the first thing that you and your guests smell!
