Optimara is Earth's largest grower of African Violets
With the widest selection of full-blooming varieties, Optimara continues to advance the industry with new plant varieties and innovative growing techniques, constantly refined over years of research and development. We create new, exciting plants and care products which are trend-setting and truly functional. Our effort is to continue offering customers a unique selection of flowers in a beautiful product line.

Our company was founded in 1904, by Martin Dorrenbach in Isselburg, in the lower Rhein Valley of Germany. By the 1930's, the son-in-law and horticulturist, Hermann Holtkamp, Sr. bred his first Saintpaulias on only one square meter (10.76 square feet) of greenhouse space.
At the time, Mr. Holtkamp said that the African Violet would be the potted plant of the future. Our company grew many different crops, later to be replaced, one by one, by the African Violet.
 
Backing up everything that Optimara grows is a uniquely energetic marketing and distribution program that makes Optimara Violets as easy to sell as they are to grow. In the design of all Optimara packaging and display materials, the focus is on minimizing set-up and maintenance, while maximizing selling power and attention-getting

At Optimara we know that our responsibility for our products does not stop after the sale. Our extensive online resources provide consumers with valuable plant care information.
From the most popular African Violet in the world to a complete line of consumer plant care products, Optimara has what it takes to make your business grow.

Optimara's History of Innovation
One of the most exciting breakthroughs in the research and development of the African Violet was in the early 1960's, with the introduction of the first non-dropping variety called Elfriede. Today all of Optimara Varieties and most all other competitive varieties available on the market have this essential genetic characteristic.

In 1961, the name of the company changed from Dorrenbach-Holtkamp Greenhouses to Hermann Holtkamp, KG.  In 1977, Holtkamp Greenhouses was founded in Nashville, Tennessee, and the Optimara brand name was introduced to the American consumer.

In 1981, we started with Optiflora, a plant care product line which also sells its products under the Optimara brand name. In 1992, the company in the USA began growing miniature Poinsettias. Over the past few years, the company has added Elatior Begonias, Rex Begonias, many varieties of ferns and foliage plants to its product line. In the future, we hope to add even more items which will give the company new and exciting opportunities in delivering a diverse product line to the consumer into the 21^st century.
