This is the first time that I am seeing the 2015 seedling shown below blooming outside. 'Knock Out' is a grandparent.
Though not as pretty, the brand new seedling shown below, is a 2016 seedling blooming for the first time inside the greenhouse. It is a first generation 'Knock Out' seedling and has the best blotch that I have seen in direct first generations descendants. As it matures, I expect the blotch to get bigger and more defined.
