How many seeds does one plant produce?
I had a particularly tall foxglove (nothing special, just a wild purple one) that had had a flower stem more than 2 ft long. When it died, I counted over120 seed heads and I picked one (admittedly one of the larger ones) and opened it onto a sheet of paper. By counting and estimating, I found there to be more than 1000 seeds, so that's 120,000 per flower stem and there were four flower stems (though not as big) on the same plant. My guess is therefore between a quarter and half of a million seeds,so I'll be more careful about disposing of dead foxgloves in future! Has anyone ever actually counted how many seeds are produced by a single plant for each species? If so, which holds the record?
