Poinsettias are very popular blooming potted plants for about a month prior to Christmas. Then, most quietly disappear prior to spring. A few become foliar houseplants. Fewer go into home gardens to likely succumb to frost or neglect. Very few survive for more than a few years. It is not easy to recover from the procedures that forced them to bloom so well.
Forcing bloom is stressful. It provides unnaturally indulgent doses of stimuli that optimize floral performance. It involves any combination of deceptive environmental and chemical manipulation. Optimal bloom is the primary objective. Sustainability or even survivability after bloom is irrelevant. Forced plants are barely more than cut flowers with potted roots.
For example, poinsettias receive much more than the nutrition they require for exemplary growth and bloom. The greenhouses that they grow in maintain optimal temperature and humidity for them. Shading shortens their daylength to deceive them into believing that it is the season for bloom. Transition from such decadence to natural conditions is difficult.
Almost all fancy blooming potted plants that are available from supermarkets and florists, and several from nurseries, are forced to some degree. These include poinsettia, orchid, chrysanthemum, hydrangea, azalea, a few types of roses and various bulbs. Such bulbs include lily, narcissi, crocus, hyacinth and tulip. Some exhaust their resources by bloom.
Many forced plants are cultivars that are distinct from more common landscape cultivars. For example, many florist hydrangeas bloom with huge and very abundant floral trusses on short stems. They are spectacular in pots, but might not be so practical for landscape situations. Landscape hydrangeas support bloom higher over the ground on taller stems.
Their potential for inferior performance after their potentially difficult recovery from forcing should not necessarily disqualify forced plants from salvage. Short florist hydrangea can be delightful accessories to bigger landscape hydrangea. Moth orchids are impressively adaptable. Premature doubting of possible ultimate results can be more effort than trying.
