Big yes for
Iris; big no for
Ivy.
They are so similar, yet so different. I think for me it comes down to simple botany -
Ivy is such an annoying plant, and irises are so lovely.
That said, I did have a great-aunt
Ivy, whom I never knew. And I've never met an
Iris.
If you Google Dietes, you should find pics of our local wild irises. They come in white or yellow, and are really cheerful.
