3 or 4 years ago I bought some beautiful blue petunias. They had a wonderful smell
for up to 10 feet away. Have not seen that kind since. Would you happen to know what kind they were? I bought them from a little stand that was set up temporarily, and is no longer there.
There are a lot of petunias with 'blue' in the name and some are fragrant. I'm not sure which one you had, but Easy Wave Blue is supposed to be fragrant...many blue petunias look purple, so you'll just have to experiment to find the one you remember.
