"By this time of year, the bearded irises in the Dry Garden are all flowering with rich, velvety purple petals, but I confess that I do not know which variety they are.
They were given to us many years ago by a friend who had also received them as a gift. None of us along the line could identify them. But a name would not make them any more beautiful."
If it is the irises in the Jewel Garden to which you refer, they are Iris sibirica, not bearded types. Unfortunately, I have not been able to establish which cultivars.
Can anyone tell me which varieties of tall bearded Iris are pictured in Monty Don's article Sprung from the Earth, on page 31 of the May 21 edition of Gardeners' World Magazine ?, the blues are so intense they look amazing. Thanks. Graham
