Yes, this Iris is indeed an "Intermediate Bearded" Iris and not a Tall Bearded Iris. For me, this Iris was an incredible grower from the day I planted it. It has been a stellar increaser, and today (11-11-15) it set a Bud and looks like it will be in bloom very soon! The unseasonably warm weather here has prompted this. I am delighted!

Crimson King is an Early blooming Historic and is a Rebloomer sometimes too which is rare for a historic! purple with a glowing transluscent crimson red tinge too it. It is wonderful, and multiplies like a weed. my son and me dug some of this up from an elderly women who must have had about 300 bulbs of it at the foot of her property and she let me photgraph it, it was a beautiful site to behold! it may be a shorter variety, but its glowing, luminesent color, is like no other iris!

What this antique iris variety lacks in height, it more than makes up for in color and fragrance!
This classic reblooming iris is powerfully fragrant, with sweet spicy notes of vanilla, oakmoss, and sometimes root beer. One flower's fragrance can fill an entire 20x20 foot room.

It is also a rapid multiplier under ideal growing conditions. One of the more drought tolerant fragrant irises, it can survive brief periods of drought, but growth rate and bloom numbers do suffer in such circumstances.
