  1. Thanks Pier,
    this works well. Thanks for using ThingLink. Interesting how yarrow can have all sorts of different colors in cultivated specimens. Here in Alaska I have seen white and pink morphs in the wild, but not yellow ones. Since this is a member of the Asteraceae there are some special terminology to consider. So the larger flowers on the edge of each invididual inflorescence are ray flowers which are zygomorphic, and have a strap-shaped, 3-lobed ligule at the end, to the inside of those 5 ray flowers you will find a number of actinomorphic disc flowers or florets, which have short united petals with 5 distinct lobes.

    Wow- I had my camera up on the highest magnification AND was wearing glasses and couldn’t see those little florets to even know they were there.
    That’s amazing!
