Plant Common Name
General Description
Infinity Red poinsettia bears clusters of fiery red flower bracts on compact, sturdy, upright plants. It was discovered in 2000 by Marga Dümmen of Rheinberg, Germany, among seedlings of a cross between two unnamed selections. Like all modern Euphorbia pulcherrima cultivars, it develops from a newly rooted cutting into a bushy, bloom-laden, market-ready plant in a matter of months. Height and width dimensions cited below are for first-year greenhouse-grown plants. Older plants attain much greater size. Wild poinsettias in the uplands of western Mexico are leggy deciduous shrubs that typically bloom on naked stems.
All poinsettias have upright woody stems with large, thin leaves and milky sap. As nights lengthen, showy whorls of large, colorful bracts develop at the stem tips around clusters of inconspicuous yellow flowers. Infinity Red bears dark-green, oval, weakly lobed leaves and bright red bracts on well-branched 14- to 20-inch (35- to 50-cm) plants. The "blossoms" develop in late fall and remain attractive for several weeks.
Poinsettias require full to partial sun and average to fertile well-drained soil. Purchased poinsettias can be moved to a sunny window or a frost-free garden niche after they bloom.
These tender ornamentals can be reluctant to rebloom because flowering is triggered by long nights. The best method is to site plants in natural daylight, where they will experience shortening days. Professional growers shade their plants at night starting around the autumnal equinox to ensure full bract coloration 6 to 8 weeks later.
Poinsettia is sometimes the subject of health concerns. See http://www.ces.ncsu.edu/depts/hort/consumer/poison/Euphopu.htm
