When we bought our house, the landscaping included several clumps of "bicolor iris". I think the scientific name might be Dietes Moraea ... bicolor. I love the blooms (pale yellow with maroon markings) but the grass-like foliage is messy looking for most of the year.
I'd like to find out more info on how to take care of these. Should I be cutting back the foliage in the winter? Should I be separating out the clumps? Also do these need lots sun and/or water to bloom? I moved some clumps last year and those aren't blooming -- they have more shade & probably less water than all the clumps that are blooming.
