Q.please can you tell me the name of what seems to be a white Iris type flower, tall stem, grows in “clumps” in Charleston S>C> pu
blic flower beds, so can take the heat of a summer. it appears to have a flower of 4 petals, not Siberian iris
I would like to try and grow it here om South UK
I think you may be referring to a Japanese Iris.
They come in blues, purples and whites.
