V. sez:
I think this depends on your zone. I am zone 6. I see
higher % bloom on established clumps than on first year
plants. First year plants generally have about a 66% chance
of blooming the first year here, regardless of where the
rhizomes came from or how short a time they were out of the
ground. Bad weather can reduce this percentage. Bud count
and stalk height generally increases on established clumps
also.
There is a commercial garden in PA that replants every
rhizome each year - this is to maximize increase, in part
by reducing the bloom the following year. Spring bloom in
their commercial beds is pitiful - but if you order from
them, you will get large rhizomes.
