The virtual monopoly on commercial poinsettia production by the Paul Ecke family for almost 80 years is a great example of floral industry economics.

Paul Ecke developed a technique for making poinsettias grow multiple branches from a single stem. The creates a fuller more colorful poinsettia plant we are accustomed to seeing at Christmas.

The Ecke family kept this a secret of poinsettia cultivation until around 1996 when university researchers were able to independently make the same discovery.

The result has been good for consumers, since poinsettias are much more plentiful and therefore less expensive than before.

Poinsettias are a Christmas tradition throughout the Americas. The plant is native to Southern Mexico and Central America.

Poinsettias are named after Joel Roberts Poinsett, the first United States ambassador to Mexico, who introduced the plant in the U.S. in 1825.

Paul Ecke of Encinitas, California was responsible for the technological advance that made poinsettias a successful commercial plant. One key to poinsettia profits is getting the plants to grow so that multiple branches come off one stem, creating a fuller, more colorful plant.

The Eckes' technique, which involved grafting two varieties of poinsettia together, made it possible to get every seedling to branch. Ecke had perfected this poinsettia secret before 1910 and his family had a virtual poinsettia monopoly for about 80 years. Around 1996 a university researcher made the same discovery and made the technique public.

Since then the Eckes Poinsettia Ranch has adapted and now is a great source of technical assistance and research funding for both commercial growers and consumers.

The Paul Ecke Poinsettia Ranch had a virtual monopoly of poinsettias that lasted almost 80 years. About 1996 university researchers finally discovered the process to grow poinsettias with many colorful blooms.

This grower is still a major player in the poinsettia market. The Paul Ecke Poinsettia Ranch website has a great deal of technical information for growing poinsettias on a commercial scale. The Paul Ecke Poinsettia Ranch also has developed a large number of varieties or cultivars of poinsettias.
