They clump and grow well together. I normally transplant them in clumps of 3-4 (mostly 4) into 4" pots and then group pots of 3-4 together in the garden.

Singles will grow ok but just don't look right to me - too lonesome and spindly looking alone. I want to see more blooms than green growth. So it is just an appearance issue.

Thank you, Dave. Just the kind of information I was hoping for.
