Re: Re:[iris Photo] Ot - Bio

Bill,
The picture that came back to my monitor was a darker cream than the picture I sent. It also was not as green. Mine is more like the one from overseas except for their lack of purple. But the purple on the picture I sent was about a shade darker than it is here and distributed right. I have a purple streak down the center of the falls that does not quite go to the edge of the flowers. I have a film camera and go to my friends to use a scanner and send the pics to myself. The scanner is old and slow and I noticed that they seem fuzzy when I send them to the e-group. I hope to get a digital the pics are so much clearer to post. To test your theory on PH I can move a piece off of the hill and put it where I have lowered the PH for my daylilies. Then wait to see how it blooms next year. Our soil here is very high in potassium naturally. I am not certain why that is.

I've sent a couple of example of Thornbird to your email address. One from a
foreign site and one (maybe mine) I do not know where I acquired. The
inconsistency we observe in the color nuances of this flower from garden to
garden is probably more than we observe in most others. In several of my
friends gardens it often blooms with a decidedly green cast. Some say gray.

This is not even theory more like wild speculation but I would think it
certainly possible that pH is a contributing factor. I would suspect that its
genetic make up is such that the purple/lavender/red tint is deposited in a
very thin layer and probably sparcely so in the falls. Potassium uptake would
be retarded at lower pH levels and increased at higher pH levels (increasing
purple/red tint). Your deeper color saturation on the falls lend support to
my supposition- If you are growing under alkaline conditions.

Certainly we cannot rule out the nuances of film, digital cameras, scanners,
monitors and such but we physically observe differences here, just not as
dramaticly, from garden to garden.

We might could just do away with test meters and test strips if we could
develop a color chart to compare Thornbird to. ( grinin' )
