Hydrangea Petals Affected by Aluminum Sulfate

Hydrangea macrophylla "Nikko Blue" petals. H. macrophylla is unique in botany, in that flower color is dramatically affected by the ph of the soil. In a low ph (acidic) soil, aluminum ions are absorbed by the roots and transmitted to the flower buds, producing a blue hue. In high ph (base) soil, the roots cannot absorb aluminum, and the flowers will remain pink or red.

Reason: Beauty of the image, also serving as an illustration of a very unusual capability posessed by H. Macrophylla. Well suited for computer wallpaper.

Oppose A bit fuzzy. It looks like the picture has been artifically coloured blue rather than natural colour. It would be more encyclopaedic if there were pink and blue flowers in the same photo. Witty lama 06:08, 10 April 2007 (UTC)[reply]
~~Support as nominator~~ Please note: There was absolutely NO digital alteration in this photo. The color was painstakingly produced through gardening Shmoopy 12:37, 10 April 2007 (UTC)[reply]

  - I believe you, I do not mean to appear otherwise - it just looks digital. If you could get a pic with the different types of colours then this impression would not occur. Witty lama 17:52, 10 April 2007 (UTC)[reply]
Oppose. Blurry - can you take another photo? Pstuart84 Talk 13:41, 10 April 2007 (UTC)[reply]
Support. Lovely example of a biological property unique to hydrangeas. Illustrates the concept well. RedPumpkin 04:33, 12 April 2007 (UTC)[reply]
- Above vote is the only contribution by RedPumpkin - possibly a WP:Sock? --Janke | Talk 07:36, 13 April 2007 (UTC)[reply]
Support- Great focus, etc --Penubag 08:27, 13 April 2007 (UTC)penubag[reply]
Oppose. No, not "great focus" - there is a clear DOF problem here. --Janke | Talk 13:25, 13 April 2007 (UTC)[reply]
Oppose—As Witty lama said, it would be better to have a picture containing both colors of petals. — The Storm Surfer 01:17, 14 April 2007 (UTC)[reply]
Oppose - although it's clearly not been tweaked for colour, it could have been better lit and you really can't expect even the best of lenses to produce FP-quality macro shots if they are set to f2.8 ... fairly encyclopedic, but not enough (agree with "both colours" comments) to forgive these errors. mikaul^talk 09:38, 14 April 2007 (UTC)[reply]
