Tanacetum densum - 2010

how do you acheve?

Sorry Xcyv, I don't understand your question. How do I achieve what?

how do you take the photo？
ps-ed？

why is your flower bright yellow，while the leaf is gray？

I have a camera with a macro facility - this allows me to get very close to teh subject and keep it in focus.
This plant has a yellow flower and grey leaves so the colours are true

yeah？
i have not seen it。what is it。

Tanacetum？
its foliage is all green，as far as I know。

No, in this one it has grey foliage - tanacetum densum subsp amani

what are densum and subsp amani ？

andrewr？

Plants have a genus name (in this case tanacetum) and a species name (densum). Where a species has slightly different variants in different locations in the wild, they may be given a subspecies as well.
