It is really great to see all the activity in the Spring 2021 group! Nice to be able to see the development of spring in all those locations.<br />A wonderful element of spring are the many flower bulbs like daffodils. I started a GrowApp series to follow the development of a field of daffodils close to my home on 29 October 2016 and made 66 photo&#39;s of the spot. Now it is nice to compare the different years. Below you see clearly that last year, 2020, was a very early year. The average of January and February was 6.7 degrees Celsius. This year it is &#39;only&#39; 3.8. Fifty years ago it 1.5 degrees was normal for the Netherlands. I&#39;m looking forward to the moment the really start to flower. You can follow the developments via GrowApp of course ;-) https://growapp.today/#/?activePhoto=86186&amp;activePhotoSet=1125&amp;fullScreen=true <br />​​​​​​​Kind regards, Arnold van Vliet, Biologist Wageningen University, the Netherlands.<br /><br /><img src="https://www.globe.gov/documents/18702582/0/20210313_Daffodils2018-2021.png/543d1590-c248-dfaf-3b1f-8426c70bcef4?t=1615622312034&amp;imagePreview=1" />
