I. reichenbachii, according to Köhlein, has a
"visible (compared with I. pumila) bloomstalk..2 3/4"-8 1/2"
(22-24cm ) tall...." Thomas Silvers' 2nd photo definitely shows a stemmed
bloomstalk. Brian Mathew says of I. reichenbachii: "This species closely
resembles I. suaveolens but is usually a little taller and has broader leaves
and a shorter perianth tube." Mathew lists it at 10-30 cm, which should
be 4" to just under 12" (but then I may be off on the translation into inches,
as I missed the whole movement to teaching metric in school.....that came
after my schooling). What puzzles me is Mathew's saying it has a
perianth tube, whereas Köhlein says it has a stem. Can an iris have both
a stem and a perianth tube? Since I grow several pumilas, I thought that
a perianth tube was different. Can anyone out there help me on
this? So, Francesca, I would guess that I. reichenbachii can fall into
either MDB or SDB range, as Mathew does state it varies in height depending on
where it grows.
