| | APSnet Feature - Phytoplasma Casts a Magic Spell that Turns the Fair Poinsettia into a Christmas Showpiece (Site not responding. Last check: 2007-10-19) |
 | | Because poinsettias typically bloom during the Christmas holiday season, a group of Franciscan priests who were settled near Taxco in the 17th century began to use the brilliant flowers in the Fiesta of Santa Pesebre, a nativity procession. |
 | | Poinsettias entered a new era when more free-branching cultivars with improved lasting foliage retention characteristics were introduced in the United States as well as in Europe. |
 | | The subtle interactions between the phytoplasma and poinsettia result in dwarfing and moderate branching growth habit, which happens to be a trait that poinsettia growers desire. |
