One of the quin­tes­sen­tial hol­i­day flow­ers is the Poin­set­tia. Orig­i­nal­ly from Mex­i­co, this gor­geous plant works well as a cut flower in arrange­ments, too. If you do choose to use the blooms in a flo­ral design, after cut­ting the stem,  seal the cut end imme­di­ate­ly by either dip­ping in boil­ing water or hold­ing over a flame for fif­teen sec­onds (use an oven mitt to pro­tect your hands). The cut flower will last about a week in a vase of water or wet flo­ral foam. Cal­i­for­nia is the top Poin­set­tia pro­duc­ing state and over $220 mil­lion worth are sold dur­ing a six-week peri­od each hol­i­day sea­son. Learn more about car­ing for Poin­set­tias.
