Nasturtiums are indeed naturally pollinated by humming birds:

``Many flowers typically pollinated by hummingbirds, such as
nasturtiums,
don't need to be fragrant because their pollination partners have
little
sense of smell.''

Now the humming bird has been mentioned, the spur's "function"
now seems clear enough - thanks!

And to confirm it, I spent a few minutes this morning nipping off
the
end of the spur on a few nasturtiums, squeezing out a drop of liquid
and
tasting its sweetness ;-)

Watch it! You'll have the Plant Rights Activists after you. {:-))
