When it comes to flower arranging, stick to this formula: height + cluster + hero. Always focus on one bloom that will be the hero of the arrangement – maybe it’s your Valentine’s favorite flower. Next, choose a flower, or a filler, that has height and structure to it. Lastly, when arranging the flowers in your vase, cluster a variety of blooms and fillers together, rather than placing multiple hero blooms together in one area.
You can buy bunches of flowers at any grocery store and some florists sell flowers by the stem, so you can purchase them for your own DIY needs. It’s always good to keep in mind which blooms will be in season for the holiday, but most stores will also provide popular blooms that may be out of their traditional growing season.
