It might just be mere coincidence, but something greater may be at play. The first open bloom this year happened on the same calendar day as last year, namely April 21. It's the red rose shown below from one of my unnamed German rose seedlings. To see last year's "twin", browse back to my post of April 30, 2015 (Ushering in the new rose year) and look for the rose photo taken on April 21.
