Gardeners' Notes:

Out of all the petunias that are called "Blue" petunias, this is the closest to a true blue. They are the blue-est looking when they first open, by the next day they they fade down to a dusty denim blue-purple.

The seeds from this Petunia seem to have the lowest germination rate out of any other petunias I've grown. Most other petunias have about a 70% germination rate, these are only about 20%.

I am currently trying to root cuttings from Blue Morn, once they start growing again I will come back and fill you in on the viability rate of the cuttings.
