    The ‘plunger pollination’ described above is one of the traits uniting the Asterales, including all composites as well as other members of the Campanulaceae … or so the experts say 🙂 In any case, it’s a fun thing to look for.

    Thanks, Daniel! The thing that really drew me to the plant and then to the composition was the height of the flowerhead – at my eye level or just a little lower. A magnificent sight.

    Thanks for this!
    I homeschool 2 boys and we were looking at plant classification today. Why was my eldest son’s plant classified in the order Asterales? One reason given was “plunger pollination”. Your photo and description enabled us to understand this reason:-)

    Doesn’t something very similar happen in some of the Proteaceae? I seem to remember being absolutely fascinated whilst in Australia some years back, to read that in, was it Grevillea, Hakea, Banksia or Lomatia (?), the stigma picked up pollen from the hidden anthers as it emerged and became ripe for pollination only later on.
    It’s hard to think of a family less closely related to Lobelia (without being a monocot or palaeodicot) so a nice case of convergent evolution. The flowers are very similar to look at too.
