Thanks to everyone for all I have learned so far! I'm a novice and have been
lurking- hoping to discover why a certain TB won't bloom. It came with the
property (my in-law's vacation cottage) and could be very old stock -- the
former owners were elderly.
Five years ago, I divided the (very large) clump and, planted fans throughout
the property hoping to find a spot where it would flourish. From full sun to
part shade, from very rich soil,improved with composted manure, to rather sandy
beds, the fans are everywhere! I must add that the foliage is lush and
vigorous. No rot problems. A few plants - those in sandy soil and full sun get
brown tips -- I assume its too dry for them. A blue siberian and a yellow and
brown bearded living in the same garden bloom beautifully.
Its a fragrant, blue iris - no ruffles, nothing fancy. I wasn't there this
year to see the single flower stalk open so I don't have any other details.
Each year, out of about 20 clumps, one or two produce a single stalk. Those
that do live in part sun.
Should I try more fertilizer? Or, are there some irises out there that don't
perform? I'm ready to give up and just enjoy the foliage -- especially now
that I've read about the exciting hybrids growing in your gardens!!
