You have foreknowledge of the exact date of various flower emergence? Why aren't you playing PowerBall?

These are average numbers, based on six years of data. The flowers are remarkably consistent, though. I would say the dates have a 95% confidence interval of +/- 3 days.

The frost dates are just based on data from the national weather service, and have more like a +/- 15 day 95% confidence interval. So I wouldn't put any money on those.

I didn't realize that you could bet on flower emergence dates, via PowerBall. If this is true I shall have to look into it.

The phases of nature are a satisfying way to measure time!
