Has anyone even heard of these. Many years ago(15 or so), I "thought" I found these in a catalog and was not into gardening at the time(youth and inexperience, you know)so of course I did not get them. I am pretty sure that a lot of small communities used these in their plantings around the turn of the century/depression era times. I have only been able to find one place that they are even mentioned to purchase seeds and they are in a mix. Am I dreaming? I am pretty sure that I didn't make this up. HELP!! I know you all will know something. I have posted in other forums, so you all are my last chance. I have done research, but maybe you all know things that I don't.
I really question that the four o'clock (Mirabilis) comes in a true blue. The feature you saw may have been about a similar-looking flower that happens to be blue, or it might be a four o'clock that is a lavendar with blue-ish overtones. No flower type in Nature appears in all three of the ~primary~ (pure) colors of red, yellow, blue. Two of them usually but not all three. Mirabilis appears in red, yellow, pink, purple and lavendar. Much time, effort and expense has been put into the effort of achieving a true red bearded iris or a true blue rose. Some cultivars seem to have been nearly there, but close examination under microscope will show a blending of undertones that achieves the effect. Yuska
I don't think they are really a true blue, though, but shades of blue/lavender or blue/purple. My clematis Rossmoor is supposed to be red, but actually is a very dark purple/red -- a long ways from actual red.
I was looking through the Baker Creek Heirloom Seeds catalog, and they listed a Marvel of peru (4 o'clock) Stars and stripes mix of "...bi-colored and splashed flowers in the colors of yellow, white, rose, red, and blue"
