Mike,
The second one is whiter and bigger. I remember the first day that I saw these two bloom. I was looking out my porch window watching my dog, when I glanced over to the far corner of the seedling area and I wondered what flower that was. In the a.m., that area is in the shade and the "white" color jumped out at me. I quickly put my crocs on and went out to see this bloom. As I approached, I also saw the first seedling. My excitement level increased, as I liked what I saw. I went to my shed, grabbed my marking ribbon and quickly marked each one. Subsequent blooms looked like the ones posted. I have other seedlings that I like, but these two were the height I like and they were large. Will have to see how they perform over the next several years. Now that I have gotten some characteristics I like, it will be interesting to see how I view my other seedlings. I am sure several will make it to the compost heap or I will give them to a local garden club to plant at a local park.
