Small calla lilies are available in a variety of colors while the large size is always white unless painted with floral paint. Calla lilies provide simple elegance when arranged in a vase and are very popular in weddings and floral centerpieces. However, problems begin when you attempt to arrange the calla lilies in a vase of water and the stems immediately begin to float out of the vase. A simple procedure can prevent stems from floating and help you make beautiful and balanced fresh calla lily centerpieces.
Fill clean vases three-fourths full of fresh clean water. A vase for a calla lily arrangement should be tall enough to accent the long elegant stems of calla lilies and have a narrow enough mouth to support the calla lilies so the calla lilies will stand up and not lean over.
Using one vase as your example arrangement, cut the first calla lily where it is at a height over the top of the vase that is 1 1/2 times the height of the vase. For example, if the vase is 6 inches high, then the first calla lily should be 9 inches higher than the top of the vase or a total of 15 inches long.
Turn the cut calla lily upside down and fill the hollow stem with water, using water from the measuring cup. Soak a small piece of cotton in water and plug the end of the calla lily with the cotton plug. Push the cotton plug far enough into the hollow stem so you cannot see it and it will be secure. Turn the stem right side up and put the stem in the vase of water.
Add the other calla lily stems, cutting to different levels, into the vase filled with water after cutting and filling the stems with water and plugging the ends of the stems with cotton. This will keep the stems from floating out of the water and stabilize the arrangement.
Finish arranging the other calla lily centerpieces as needed so centerpieces will be as similar as desired.
