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. After the war Hermann Holtkamp Sr. intensified his breeding efforts and by the early 1950's, the first real success gave the breeder hope for the plant's future.
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.

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 characteristic.
