Last weekend the daffodils were coming up, and this week all the almonds, pears, apples and early stuff really started to pop. I just spent 3 hours driving the German and French Wine Road from Neustadt to Wissembourg and it was beautiful. Also very crowded, as just about anybody who could put the top down was out also. The next two weeks are going to be prime time for spring flowers in the Alsace-Lorraine and the Rheinpfalz.
Check the local calendars as there are a lot of small towns with spring flower / Easter fests.
