I have planted mine in patches of 9 plants, one space between each. I have had good luck with hybrids. Lately I have been moving the hybrids to a 9 patch of their own. I have 5 different hybrids so far, and today I have 2 new plants growing in the hybrid patch. Sadly my blue Rose was in my first town that was wiped out by the great storm of 2016. Took everything, and all the people. Had to build it back from the ground up.
