This is unreal, February 27, and the flowers are out on my plum tree. I knew it was crazy early, but was curious about the dates I had posted first plum tree flowers in previous years. Well actually I tweeted something about this, and Tony Hirst prompted me to futz around with my photo data
@cogdog do you tag consistently (ie can tags be harvested and bring with them dates)?

I had not tagged them consistently, but using the Flickr organizer, I was able to find the first photos each spring, and tagged them firstplumflower
These dates where:
- apr 3 2006
- mar 27 2007
- apr 4 2010
- apr 2 2011
- apr 4 2013
- feb 27 2014
I was also able to come up with data on the first daffodil flowers, tagged as firstdaffodil
Not content with that, I put them in a spreadsheet, and for comparison, converted the dates of each to the day number of the year:
and charted up nicely….
So what have I shown? Probably not much. Over a long time period there is likely an average first day that the data here is fluctuating about, even with today being more than 4 weeks earlier than previous for the plum blossoms.
I was intrigued that I had this data, though with the caveats:
- I was not living here full time until 2008, so before that year was dependent on the weekends I came up yo Strawberry
- I was not here at all in 2012
- It assumes I took a photo of the first flower, I might have missed it by a few days.
- The dates selected the first open flower, not just the buds
- It’s interesting that the plum flowers came out first in 2014– usually the daffodils are the first flower out of all. What does this mean?
- The plum tree was trimmed only in December of 2011 and 2013
- I could do this for tulips as well… usually out about 2 weeks after the daffodils.
Still, as I think Tony was suggesting, if this was done by more people, in different location, it might be something worth doing less manually then my lame charting.
