Re: REB: current status

I really don't know enough to comment on this, but that hasn't ever
stopped me before, so..

Some rebloomers here seem to go into some kind of stall that requires
cooler temperatures <plus> a lot of water to get them going again.  They
don't necessarily lose their foliage (like the aphyllas usually do
here), but just hunker down and wait till after a few nights with autumn
temperatures.  Then they put on a flush of new, lush growth & start
trying to produce bloom stalks.

If the weather cooperates, & we get a night or two in the 40s in August,
plus enough rain to really soak things (might take 3 or 4 inches after a
month of drought), fall bloom on these is early.

Some of the G.P. Brown & Jensen <everbloomers> <don't> seem to need
those cool nights and will keep growing and blooming here as long as
they get a lot of rain and nutrients.  SUMMER WHITEWINGS, SUMMER
GREENSHADOWS, BELVI QUEEN.

At one time, most of my most reliable once bloomers were losing their
foliage during prolongued summer heat and dry spells.  Best example is
SULTRY MOOD - it keeps its foliage when it gets enough moisture here,
but when it's really hot & dry for a while, it looks like a midwinter I
variegata or pallida.  Nothing but little nubs of terminal shoots
waiting for good times to return.

<I had been under the impression that the genetics that keep this kind
of dormancy from happening was one of the characteristics all rebloomers
shared.   Guess that isn't true--at least not always.  Neil Mogensen  z

Talking away while I wait to hear if the baby whooping cranes made it to
Tennessee today and wondering where the adults are - some started
migration late last week & should be here any day....
