That must be it. What is happening (educated guess) , is that the SDB,
which grow fast in spring anyway, are growing in your climate, before
they get the photoperiod which stimulates the flower stalk growth
(flower bud initiation). Thus the daughter increases will have advanced
too far to have flowering inhibited by mother rhizome.

This could be part of the reason that MDB and SDB don't do well in
regions farther south. Too much plant growth before the lenght of
daylight needed to trigger bloom, hence bloomout.

Probably a couple of weeks of growth before the first
stalks on the SDBs, maybe that is the problem? Usually growth is heavy
followed by almost every fan putting up a stalk on the ones that are
prone to bloomout.

The time between SDB and TB peaks would seem to be the same as what I

get here. About 3 weeks.

Do you get much growing time before bloom starts? Here the SDB

plants start putting up as soon as they get some good growth.
