Remember what I said about sticking to one color when you arrange flowers? Well, scratch that. (Kinda.)
Although choosing monochromatic flowers is a no-fuss way to make a centerpiece, another one of my favorite ways to use flowers is to do the opposite: choose one type of flower in many different colors. I like to place each stem in a clear glass container, then cluster the vases together to create a garden-like effect. Stick to one type of bloom that comes in a rainbow of hues. Roses, ranunculus, daisies, tulips, and calla lillies are a few good options. Fancy vessels aren't necessary. You could use jelly or Mason jars, tall drinking glasses, or other containers like this cool test tube contraption I got as a gift.
Separating the stems into smaller containers makes a bigger impact than a bunch of blooms in a single vase. The display is ideal for a mantle or you could run the vases down the center of your dinner table for a runner-like effect. Just stick to low containers and keep the stems short so people can see each other.
