Some people have a well marked preference for flowers known as “rainbows”. As the title above suggest, there are flowers that have the capacity of transmitting the “rainbow condition”, or to transform others into “rainbows”.
These sometimes don’t have the looks of a “rainbow”, however, they have amazing qualities themselves. Let’s talk for example, about Moorea Sublime A., a red flower with more or less violet edges. But M. Angela’s Rainbow however, descends from Moorea Sublime A. As a matter of fact, a “rainbow producer” is not a “rainbow” due to its color. A hybridizer always keeps account of the past experiences, looking towards the self improvement. By trial and error with many flowers, it is possible to note certain tendencies that may help with his quests, as there are flowers with the capacity of concentrating, dispersing or even mixing in a higher or lesser degree, one or several colors. Of course, all these personal experiences are part of a rather personal field the hybridizer will care not to disclose, to avoid any plagiarism.
Some in the world choose to work with the “rainbow” option, in which they self-assuredly stand out. When a flower is given the “rainbow” name, it does not necessarily mean that it conspicuously is one, nor that is capable of transmitting such characteristic, as the term is often used as a mean to acknowledge its predecessors.
How many colors must a flower have to be called a “rainbow”? Aside from specific cases, I personally think that a true “rainbow” should have five colors, but in many cases, three or four seem enough for the name to be given. Flowers with five to seven colors are rare and sometimes can not transmit the desired genes. Furthermore, their name does not compulsorily carry the “rainbow” denomination, despite the superior color quality.
We could get “rainbows” in different shades: more or less degraded maroon, multi-colors (white, red, pink, orange, etc.), superimposed, etc. However, as I have stated before, this doesn’t mean they are capable of transmitting the “rainbow” condition. What this means is that, in order to obtain “rainbows”, only experiments with them will show the real potential of the “rainbow” type flower.
Summarizing, we can say that a “rainbow” flower can be called like that because of its capability to transmit such condition, hence the name “rainbow producers”. But there are also flowers with the “rainbow” name on them that lack all capacity to transmit it.
