    Title is a dead giveaway. pH.

    Acidity.


  3. Acidity of the soil

    Soil pH. That’s the mophead flower (Hydrangea)

    Hydrangea Flower .
    flower colour shows the pH of soil
    acidic soils produce blue flowers
    neutral soils produce very pale cream petals
    and alkaline soils results in pink or purple


  6. Kaushik

    Hydrangeas

    In these species the exact colour often mirrors the pH of the soil; acidic soils produce blue flowers, neutral soils produce very pale cream petals, and alkaline soils results in pink or purple. This is the caused by a color change of the flower pigments in the presence of aluminium ions which can be taken up into hyperaccumulating plants

    The level of acidity AND the presence of aluminum.


  8. The ph value :) nice clue, I like !

    Hydrangeas, the color indicates the pH of the soil.

    Hydrangeas. The pH value of the soil causes the color change. More specifically,
    more Aluminum content in the soil = less pH value –> blue color.


  11. rr

    it is the *mod-edit* detctor

    The Hydrangea flower acts as litmus paper and indicates soil pH levels: acidic soils produce blue flowers, neutral soils produce very pale cream petals, and alkaline soils results in pink or purple.

  14. abhijeet

    litmus??

    Simple one.

    Hydrangea, soil pH


  16. Andre

    It is affected by the soil’s pH


  17. sidsen

    ph


  18. Siddarth Pai

    The acidity or alkalinity of the soil
    like litmus paper
    the pH level


  19. Hydrangea macrophylla blossoms are either pink or blue, depending on a pH-dependent mobilization and uptake of soil aluminium into the plants.


  20. PrK

    Hydrangea macrophylla
    Flower color, which is variable depending on soil pH, will be pink in alkaline soil, with acidic conditions turning the flowers blue.

    Color of Hydrangea varies with the pH of the soil.
    Acidic soils produce blue flowers, neutral soils produce very pale cream petals, and alkaline soils results in pink or purple.

    Soil pH.

    The colours are known as Nikko Blue, and Forever pink.
    the flower is hydrangea.


  24. Hydrangeas change color based on acidity of the soil.


  25. GhoSTWhoWALKS

    Hydrangea….


  26. Sridhar C

    The color indicates the pH of the soil

    hydrangeas, litmus paper of the soil


  28. Ps

    Changing a hydrangea from pink to blue entails adding aluminum to the soil. Changing from blue to pink means subtracting aluminum from the soil or taking it out of reach of the hydrangea.

    There is an input problem on the captcha


  30. Ps

    p.s. also the colour is apparently based on the soil PH so that the answer u prolly looking for


  31. alephnull

    Hydrangea. Depends on acidity, iirc.


  32. Chitananda

    pH of the soil – hydrangea flowers


  33. GhoSTWhoWALKS

    Hydrangea…


  34. Siddhartha Mohapatra

    pH value of soil


  35. Sridhar C

    The pH of the soil


  36. piezocake

    Acidic / alkaline.


  37. Mo

    pH, which can be less than 0?

    Blue color indicates aluminium in soil
