Re: CULT: TB Questions

I've grown Eleanor Roosevelt, but I'm not familiar with Abe Lincoln. Are you positive it's a TB? 


""Abe Lincoln""

So has my wife; though I'm only 5'10". Wonder how Abe Lincoln might have
been?

Hi BJ,

I've spent a lot of time contemplating the performance, or lack
thereof, of tall beardeds in my beds over the years.
1. What causes increases to happen in Iris (I know how it happens 
with

lilies)


No idea
2. Do TBs bloom too late for the increase to form and then grow 
large

enough to form a bloom next year


I never thought to factor in the lateness of TB bloom relative to the
other beardeds, but I have assumed that there isn't enough time during
our short growing season for TBs to grow increases to blooming size in
a single growing season ... or necessary in two or three growing
seasons.  I also think the sheer size of TB rzs requires a lot more
growing time than our season allows.  Most MDBs, SDBs, IBs, and MTBs
bloom annually for me unless we have a really problematic weather
pattern like last winter-spring-summer and this spring.  The smaller
bearded classes grow to maturity much more quickly than TBs.


3.  Are our summers not hot enough for the rhizome to form in time to
be able to get ready for winter and winter over
I don't think that's a factor in my climate. We typically get a LOT 
of

summer heat.


4.  Something else??


I think #2 is the primary - perhaps even the only - explanation.
That's why I no longer add new TBs to my iris beds unless they are
given to me as gifts.  I just don't want to waste the space on irises
that have such a high mortality rate here, esp. when even those that 
do

manage to survive are such inconsistent bloomers and weak increasers.
Of course there are a few exceptions, and my garden will always have
room for them.

Laurie
