NOVELTY POINSETTIA PRODUCTION

G. J. Wilfreti

Most production of poinsettia plants for the Christmas holidays consists

of a single pinched plant grown in a 6 or 6.5 inch container with 5 to 8

inflorescences. Specialty growers also plant three cuttings per 6 or 6.5 inch

pot and grow them unpinched, which makes a larger inflorescence and floral

display. Unfortunately, an abundance of the plants grown in 6 or 6.5 inch pots

has saturated some local markets, forcing growers to seek novel ways to grow

poinsettias to increase their sales. Some of these "novelty items" are hanging

baskets, hanging gardens, 4 to 4.5 inch pots, mini-trees and standard trees.

Growing poinsettias as trees was made possible with the introduction of

Gutbier's 'V-14 Glory' in 1980 and Gross's 'Supjibi' in 1985. These cultivars

were adapted to tree culture because of their strong lateral branches, large

bracts, and earliness to flower. Previous attempts to use the Annette Hegg or

Mikkelson cultivars as trees failed, either because of their weak laterals or

lateness of flowering. Research at the Gulf Coast Research and Education Center

at Bradenton (Univ. of Fla.) has modified the tree production methods of Paul

Ecke Poinsettia (CA) and developed a technique to produce poinsettia trees of

various sizes in Florida. Research has also shown how to produce quality novel

plants in other size containers. Listed below are guidelines for production of

these novelty poinsettia plants.
