RE: HYB: TB: Extending Cultivar Bloom Period

Funny you should mention this but as I was stripping out the old stalks
today I noticed that EVERY stalk on Almaden had a normal stalk and a very
low "branch" or secondary stalk that joins with the primary just at the
level of the rhizome.  This greatly increased the time that Almaden was in
bloom.

Put your thinking caps on and go back with me to bloom season [in the south,
anyways  :) ]  Many cultivars have a very desirable habit or trait of
producing multiple and/or staggered bloomstalks. This highly desirable
feature produces a longer bloom period with stalks in various stages of
development.


I have seen this accomplished in two ways. A single rhizome can send up a
primary stalk followed by secondary stalks, usually with fewer buds per
stalk. The second is for a clump or a section of row-cropped plants to
produce stalks at staggered intervals. My own Mystery Blush ('99) has been
seen to perform in the first example in more than one season. It seems
likely that this trait has been inherited from the Vanity line. Lacy Day
(Ernst, '00) also sent up secondary stalks from a single rhizome this season
on its maiden bloom in my garden. Examples of the second phenomenon with
stalks in various stages of development are Keppel's Vienna Waltz ('00) and
Schreiner's Harvest Faire ('98).  One stalk starts growing and develops and
then a few or serveral days later another stalk emerges from a second
rhizome and ends up opening 4 or 5 days after the first stalk has begun
bloom.  This culitvar then remains in bloom longer than say Cultivar B which
essentially has all its stalk begin emering within one to two days of each
other.

If breeders, growers, and judges alike could access the information and
observe it, they could use it wisely to breed other cultivars with either
trait, extend the iris season in a garden, and vote awards to these high
performance jewels.

NOW, your turn.  Reply to the list with observations of the cultivars you
have seen exhibiting these traits and extending our enjoyment of irises.
