REB: Immortality

So much for my theory about rebloomers (especially cold climate ones)
needing cool soil temperatures to initiate rebloom - one patch of
IMMORTALITY has another stalk up.  Previous one finished blooming last
week.

I can't begin to remember what the temperature was like 6 weeks ago, but
I'm pretty sure nights weren't down to the 50s.

This clump has a heavy mulch of raw horse manure (mostly just 'apples'
picked up out of the field) covered with a thick mulch of fresh shredded
oak bark from the local sawmill.  6 or 8 inches of manure last winter
(now mostly decomposed), 4 inches of bark.  Nearly full sun - some very
late afternoon & early morning shade.  Soil thermometer hasn't been
below 60 for a long time.

Nothing else has tried to rebloom, but no other rebloomers have had
quite as much heavy mulch.
